But there’s a harsh reality - Published: 2025-04-14 - Modified: 2025-04-14 - URL: https://blog.warmy.io/blog/how-to-avoid-email-blocks-lessons-from-ms365s-deliverability-research/ - Categories: Blog - Tags: Industry insights Email deliverability—crucial yet often elusive goal for businesses aiming to connect with their audience. But there’s a harsh reality: As good as your content is and as personalized as your outreach is, if your emails don’t reach that inbox, they just don’t work. In a time when inboxes are bombarded with spam and unwanted emails, it’s essential to ensure your emails are received in the first place. Yet, maintaining high deliverability rates is complicated. Plus, it is influenced by numerous factors like sender reputation, email content, and sending patterns. These challenges are even more pronounced for businesses that use Microsoft 365 (MS365) as their email service provider (ESP). MS365 is a prevalent email provider used by many organizations, but its relatively strict filtering mechanisms means that even legitimate outreach can often be mistakenly flagged as spamThis research dives into the intricacies of email deliverability for MS365 sender accounts. Specifically, it examines how controlled warmup strategies—gradually increasing email volume and varying content formats—affect the performance of MS365 as a sender when targeting major email providers like Gmail and GSuite.  The findings from this study provide valuable insights into the best practices for improving email outreach, preventing blocks, and optimizing sender reputation for higher inbox placement rates. Research methodology: How we tested MS365's deliverabilityTo gain deeper insights into the intricacies of MS365’s email deliverability, we conducted a series of controlled experiments. These tests were designed to evaluate the impact of different sending volumes, content formats, and provider-specific factors on inbox placement.  A close look at warmup schedules... --- ### The Email Deliverability Playbook: 5 Key Trends That Will Define Inbox Success in 2025 > Welcome to the new email landscape where email deliverability has never been more important. With inbox providers tightening their rules - Published: 2025-04-07 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/the-email-deliverability-playbook-5-key-trends-that-will-define-inbox-success-in-2025/ - Categories: Blog - Tags: Industry insights Welcome to the new email landscape where email deliverability has never been more important—or more complex. With inbox providers tightening their rules, AI-driven filters evolving fast, and new privacy laws rolling out across the globe, what worked last year simply won’t cut it in 2025. The Warmy. io Research Team created this guide: to give Warmy users a clear, actionable overview of the most important deliverability trends for the year ahead. Whether you’re a solo founder or managing campaigns at scale, these insights will help you stay compliant, land in the inbox, and get the results you need. Key trend #1: Authentication or oblivion—why SPF, DKIM & DMARC are now non-negotiableEmail authentication is no longer a nice-to-have—it’s the baseline requirement for anyone who wants to land in the inbox in 2025. Q: What are SPF, DKIM, and DMARC and why are they relevant for deliverability? A: This “email trinity” is a set of email authentication protocols that verify whether an email is legitimately sent from your domain. They help protect against spoofing and phishing, and are essential for building trust with inbox providers. Without them, your emails are more likely to land in spam or be rejected entirely. 🔖 Related Reading: SPF, DKIM, and DMARC: Boosting Email Security and DeliverabilityWhat's changed in 2025? In early 2024, Google and Yahoo began enforcing strict authentication requirements for high-volume senders (those sending more than 5,000 emails/day). Now, Microsoft has followed suit, announcing similar rules for all bulk senders starting May 5, 2025. What does this mean for you? Emails that fail... --- ### SMTP Error 451 4.4.2 – Bad Connection to Remote Mail Server: Causes & Fixes > In this guide, we’ll walk you through what causes SMTP Error 451 4.4.2, how to troubleshoot and fix it - Published: 2025-04-02 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-451-4-4-2-bad-connection-to-remote-mail-server-causes-fixes/ - Categories: Blog - Tags: Email Deliverability You’ve just sent a high-stakes email to a potential client, pressed send, and anxiously waited for the response that could yield a big contract. But instead of that response showing up in your inbox, you receive an ominous message: SMTP Error 451 4. 4. 2 – Bad Connection to Remote Mail Server.  This error delays important communications and raises red flags about your email infrastructure, connectivity, and reputation. Luckily, this isn’t a dead-end situation. In this guide, we’ll walk you through what causes SMTP Error 451 4. 4. 2, how to troubleshoot and fix it, and most importantly, how you can take steps to prevent this disruption from happening in the future. What is SMTP Error 451 4. 4. 2? SMTP Error 451 4. 4. 2 is a transient error when a mail server has problems connecting to a remote mail server. This error message generally indicates that the server could not send the email because it couldn't connect properly to the mail server at the receiving end. What happens then is the email is not delivered right away and it remains pending in server’s queue. Most of the time, SMTP Error 451 4. 4. 2 doesn't signal a permanent issue but a temporary one. But if you ignore it and it stays unresolved, it can create delays, even worse—bounce-backs or rejections.  So if you see this error, remember it’s not necessarily cause for panic. It’s simply a warning that your message had trouble getting through at the moment.  Primary causes of SMTP Error 451 4. 4. 2This issue can arise due to multiple underlying reasons from network interruptions to server misconfigurations. Pinpointing... --- ### SMTP Error 421 4.3.0 – Temporary Mail Server Error Causes & Fixes > In this guide, we’re going to explain exactly what SMTP Error 421 4.3.0 means, why it happens, and how you can resolve it quickly. - Published: 2025-04-01 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-3-0-temporary-mail-server-error-causes-fixes/ - Categories: Blog - Tags: Email Deliverability You’re blasting out emails—perhaps a newsletter, an onboarding sequence, a sales drip—and you hit a wall. Your computer displays “SMTP Error 421 4. 3. 0. ”It’s a frustrating message that means your email didn’t go through. Even worse, it’s a bit vague. What does it really mean? Is something broken? Are your emails being blocked? The good news: it’s a temporary error. The bad news? Failing to address the underlying issue could lead to a cycle, and this repeated behavior can very well have a negative effect on your email deliverability in the long run. In this guide, we’re going to explain exactly what SMTP Error 421 4. 3. 0 means, why it happens, and how you can resolve it quickly. We guide you through solutions and ways to prevent it from happening on your server in the future, whether you're using your own mail server or an SMTP relay service. What is SMTP Error 421 4. 3. 0? SMTP Error 421 4. 3. 0 is a temporary issue that occurs when a mail server can’t process your email request at that moment. It doesn’t mean your message’s been outright rejected, but that the server’s too busy or lacking in resources to take it on at this moment in time. SMTP response codes fall into two main categories:Temporary errors (4. x. x): These are issues that are not permanent and can often be resolved after a short delay. Permanent errors (5. x. x): These indicate a failure that cannot be resolved by simply retrying. The “421 4. 3. 0” error specifically refers to a temporary failure due to system resource issues. The "4" indicates a temporary... --- ### SMTP Error 502 5.5.1 – Command Not Implemented: How to Fix It > If you’ve ever had to deal with the dreaded SMTP Error 502 5.5.1 – Command Not Implemented that occurs while attempting to send an email - Published: 2025-04-01 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-502-5-5-1-command-not-implemented-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability If you’ve ever had to deal with the dreaded SMTP Error 502 5. 5. 1 – Command Not Implemented that occurs while attempting to send an email, know that this is actually much more common than you might expect. Especially when you want to send out emails immediately, this error proves confusing (and frustrating) because it breaks your workflow and delays communication. So what does it actually mean? In simple terms, SMTP Error 502 5. 5. 1 basically means that the SMTP server you’re in communication with does not recognize or support a command your email client is attempting to send. This might be due to outdated software, misconfigured server settings, or unsupported authentication methods. The good news? It’s fixable. In this complete guide, we’ll explain exactly what the error means, its causes, how to troubleshoot it, and the fixes to get you emailing again. What is SMTP Error 502 5. 5. 1? SMTP Error 502 5. 5. 1 is an error message returned from the mail server of the mail client, informing the mail client that the mail server does not recognize or support an SMTP command. Now, let’s dissect the error code:502: Standard SMTP status code. You can explore other SMTP Errors with 502 code here. 5. 5. 1; Enhanced status code indicating a syntax or command issueThis typically happens during the initial handshake between the email client and the SMTP server.

But even the most well-written email is worthless if it never makes it to the inbox. That’s where email warm-up and authentication come into play—and why understanding their intersection is no longer optional. However, the email landscape continues to become even more complex. Security standards are tightening, legacy protocols are fading, and mailbox providers are smarter—and stricter—than ever. This means the rules around how emails are sent, authenticated, and received are shifting fast. This research report was born out of that complexity. It blends Warmy’s internal findings with official documentation and real-world email infrastructure trends to give you a clear, up-to-date view of what’s happening behind the scenes—and what you need to do to stay ahead. The premise: Understanding inbox warmup and email deliverability Inbox warmup is the practice of gradually building trust with mailbox providers. Think of it like building credit. When you open a new bank account or get a new phone number, you don’t immediately start making large transactions or calling hundreds of people. You build a track record first. Warmup works the same way for email. By starting with low sending volumes and slowly increasing activity, your email address begins to appear more legitimate in the eyes of spam filters. A proper warmup process includes opening emails, replying to them, marking them as important, and even removing them from spam folders. These behaviors signal positive engagement, helping email... --- ### SMTP Error 421 4.7.27 – Connection Rate Limited: Causes & Solutions > If SMTP Error 421 4.7.27 lands in your lap, it’s a warning sign—a gentle reminder from the email gods to stop - Published: 2025-03-27 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-7-27-connection-rate-limited-causes-solutions/ - Categories: Blog - Tags: Email Deliverability A lot of email senders simply click 'send' without much thought. That’s because email has become routine—a feature of everyday life. But for email senders who rely on the channel for marketing or outreach use cases, a lot is happening behind the scenes. You write an irresistible subject line, you nail the content, and you’re ready to hit “Send. ” But instead of hitting your recipients’ inboxes, your emails bounce back with a cryptic message— SMTP Error 421 4. 7. 27 – Connection Rate Limited. What just happened? Why is your email server suddenly playing gatekeeper?  If SMTP Error 421 4. 7. 27 lands in your lap, it’s a warning sign—a gentle reminder from the email gods to stop, slow down and play by the rules. In this guide, we’ll explain why this error occurs, how to resolve it, and best practice  to help your emails be delivered without errors. What is SMTP Error 421 4. 7. 27? SMTP Error 421 4. 7. 27 – Connection Rate Limited is a response from an email server indicating that the sender has exceeded the permitted number of connections within a specific timeframe.  This error isn’t a permanent rejection but a temporary speed bump in your email-sending highway. That means either your email server (or the recipient’s server) is hitting the brakes on your connection attempts. You’ve hit a rate limit, and your emails are being throttled before they can even land in an inbox.  You’ve triggered a rate limit, and your emails are being throttled before they even have a chance to land in an inbox. Think of it like trying to board a packed train... --- ### SMTP Error 555 5.5.2 – Syntax Error: Causes & Fixes > It can feel like hitting a wall when you run into SMTP Error 555 5.5.2—and everything seems to be configured correctly. - Published: 2025-03-27 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-555-5-5-2-syntax-error-causes-fixes/ - Categories: Blog - Tags: Email Deliverability It can feel like hitting a wall when you run into SMTP Error 555 5. 5. 2—and everything seems to be configured correctly. So whether or not you happen to be a developer sending emails programmatically or an IT admin managing a mail server, this error can be a clear indicator that something is amiss at the protocol level. In this guide, we’ll decode the 555 5. 5. 2 error, show where it most commonly appears (like in logs or SMTP responses), and explain how mail servers interpret it. More importantly, you’ll receive actionable, practical fixes to get your emails flowing smoothly again—all without having to become a mail server wizard. What is SMTP Error 555 5. 5. 2? SMTP Error 555 5. 5. 2 is a syntax error that occurs during the email delivery process when a command, typically MAIL FROM or RCPT TO, is not properly formatted. It's a subset of SMTP Error 555. This error informs the sending server that the receiving mail server is unable to parse the command due to syntax error—often a malformed email address or some required formatting elements like angle brackets missing. “555” indicates a permanent failure, and “5. 5. 2” specifically means a syntax error in the SMTP conversation. From the viewpoint of a mail server, this error is a defensive tactic. It keeps malformed messages from entering the system, thereby assisting in guarding against spam, spoofing, and abuse. The receiving server expects specific SMTP command formats and will immediately reject anything that deviates from the standard. So when it throws a 555 5. 5. 2 error, it’s essentially saying: “I don’t understand... --- ### Understanding ESP Blocks: Causes, Types, and Prevention > This report is more than just an overview. It is carefully tailored to support Warmy users in maximizing their email deliverability - Published: 2025-03-25 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/understanding-esp-blocks-causes-types-and-prevention/ - Categories: Blog - Tags: Industry insights Predictions show that by 2027, there will be 408. 2 billion emails sent per day. What does this mean? It shows how big a role email has in everyday life. For businesses and individuals depending on email as primary means of communication, the ability to land in the inbox is everything.  That being said, email deliverability is the unsung hero behind every successful campaign.  However, amidst the hustle to craft the perfect email, most are blindsided by a common yet misunderstood hurdle—email blocks. These blocks can impede your efforts, sending your email to a temporary deferral status or a permanent spam folder placement—ultimately damaging your sender reputation. Warmy’s research team decided to take a deep dive into the inner workings of email blocks—causes, types, and prevention strategies. But this report is more than just an overview. It is carefully tailored to support Warmy users in maximizing their email deliverability. So whether you’re new to the concept or have experienced the frustration of blocked emails, this report will empower you with the knowledge to keep your outreach smooth, effective, and, most importantly—in the inbox. What are ESP blocks? Email Service Providers (ESPs) such as Gmail, Outlook, and G Suite (now Google Workspace) are at the core of controlling the emails that get to their users. They rely on sophisticated algorithms and filters to decide which emails get delivered to the inbox and which are marked as spam or, even worse, blocked altogether. This decision is based on sender reputation, email content, engagement rates, and much more. So if an email looks... --- ### SMTP Error 550 5.2.1 – Mailbox Unavailable: Causes & Fixes > The number of emails sent and received worldwide per day is predicted to reach 408.2 billion by 2027 - Published: 2025-03-21 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-550-5-2-1-mailbox-unavailable-causes-fixes/ - Categories: Blog - Tags: Email Deliverability The number of emails sent and received worldwide per day is predicted to reach 408. 2 billion by 2027. This only shows how important people and businesses perceive email as a communication channel. One of the most common email deliverability problems that email senders and administrators come across is the SMTP Error 550 5. 2. 1. The reason for this error message being sent is when an email cannot be delivered as the recipient mailbox is unavailable. This can be a big issue for those whose businesses or sales are dependent on email to reach others, like marketing efforts. It may be okay for you to tolerate this mistake once, but this will harm your business in the long run the error continues to occur. In this guide, we will help you understand what SMTP Error 550 5. 2. 1 is, how to check mailbox availability, and actionable suggestions to resolve this error. What is SMTP Error 550 5. 2. 1? SMTP stands for Simple Mail Transfer Protocol, which is an industry default standard used to send emails over the internet. When an email message is undelivered, an error message is sent to the sender. This SMTP Error 550 5. 2. 1 points to an issue related to the mailbox of the target receiver. The full error message usually reads something along the lines of “550 5. 2. 1 Mailbox unavailable. ”This is one of the SMTP 550 error codes and commonly indicates that the email sent cannot be delivered and is a permanent failure. To be more specific, Error 550 5. 2. 1 refers to issues with the recipient’s mailbox that prevent the email... --- ### SMTP Error 554 5.4.6 – Too Many Hops: How to Fix It > SMTP Error 554 5.4.6 "Too Many hops" is one of the most common errors faced by email administrators. - Published: 2025-03-21 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-554-5-4-6-too-many-hops-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability SMTP Error 554 5. 4. 6 "Too Many hops" is one of the most common errors faced by email administrators. It happens when an email message gets more “hops” than allowed while being passed along between mail servers.  To be more specific, this error happens because an email has already "hopped" through several servers. It can then be flagged as problematic and get rejected by the next recipient's email provider. This issue not only disrupts the delivery process, it also delays communications. Ultimately, this results in lower sender reputation that can impact the business in the long run.  That is why you should know the steps to take when you see the SMTP Error 554 5. 4. 6 error message, and this guide will assist you in doing so. What is SMTP Error 554 5. 4. 6? SMTP error 554 5. 4. 6 indicates an email has taken too many hops and traveled off course with a distance greater than needed. SMTP means Simple Mail Transfer Protocol, and it is a messaging protocol responsible for sending emails. The “Too Many Hops” error comes from the protocol, which limits how many hops or relays an email can take. So, when an email crosses this threshold, it sets off a “Too Many Hops” error, meaning the message has been routed through too many servers and probably isn’t going to make it to its destination. Q: What are "hops" in email routing? A: In email delivery, a "hop" refers to the journey from mail server to mail server. Each event and each server the email goes through is one hop. This... --- ### SMTP Error 421 4.7.30 – Temporary Ban Due to Abuse Detection How to Fix It > You’ve crafted the perfect email campaign, targeted your audience, and hit “send.” But then, an unsettling notification appears in your inbox - Published: 2025-03-21 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-7-30-temporary-ban-due-to-abuse-detection-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability You’ve crafted the perfect email campaign, targeted your audience, and hit “send. ” But then, an unsettling notification appears in your inbox—SMTP Error 421 4. 7. 30. Your emails are temporarily blocked. What now? If you’ve ever experienced bounced emails and delivery failures, you know email deliverability is really important. The dreaded 421 error is the bane of every bulk emailer—the roadblock in front of anyone trying to send bulk emails in the name of marketing, customer outreach or sales follow-ups. If this is only the first time you encounter the error, it might just seem like a minor hiccup. However, it can affect your reputation in the long run if not handled appropriately. In this article, we’ll explain what SMTP Error 421 4. 7. 30 actually is, why you get it, and most importantly how to resolve it.  What is SMTP Error 421 4. 7. 30? SMTP Error 421 4. 7. 30 is a temporary error that occurs when an email provider detects potential abuse or spam-like behavior coming from an email sender.  The error message appears as: “421 4. 7. 30 – Temporary Ban Due to Abuse Detection”, and this response is given when the sender's account, domain or IP address has been caught in the act of violating policies for sending emails. What this means is that the email provider has put a temporary block for the sender to send an email due to suspected malicious activity or other harmful patterns. Often, this suspension is temporary, and lasts for hours or even days. While under this restriction, the sender is unable to deliver emails to recipients within... --- ### SMTP Error 552 5.2.2 – Mailbox Full: How to Fix & Prevent It > SMTP Error 552 5.2.2 is an error that indicates that the recipient’s mailbox has reached its storage limit. - Published: 2025-03-19 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-552-5-2-2-mailbox-full-how-to-fix-prevent-it/ - Categories: Blog - Tags: Email Deliverability It is a fact: Email communication is one of the most important aspects of daily business and personal interactions. On the other hand, there are times when emails do not reach the recipient, resulting in annoying delivery errors.   For example, SMTP Error 552 5. 2. 2 is an error that indicates that the recipient’s mailbox has reached its storage limit. In this guide, we’ll explain why this error happens and how email users and system administrators can fix and even prevent it. These solutions can help you keep an organized inbox to guarantee smooth business email communication. What is SMTP Error 552 5. 2. 2? SMTP Error 552 5. 2. 2 occurs when an email cannot be delivered because the recipient’s mailbox has exceeded its storage limit. When a mailbox fills up, all new incoming emails get rejected with bounced messages with a Mailbox Full error. This problem can have devastating effects to individuals, businesses, and IT administrators—resulting in communication disintegration and delay. This error is frequently seen in email systems with strict quota limits from the email providers such as free accounts or business accounts that have a limited storage. Why does SMTP Error 552 5. 2. 2 happen? In basic terms, SMTP Error 552 5. 2. 2 occurs when an email server rejects an incoming message because of a full mailbox. That being said, there are actually several factors that contribute to this issue—ranging from storage limits imposed by providers to inefficient email management practices. Below are the most common reasons why this error occurs. ISPs or email providers set storage limitsMost email providers, including Gmail, Outlook, and business-hosted email... --- ### SMTP Error 421 4.7.28 – IP Temporarily Blocked: Causes & How to Fix It > If your emails are suddenly bouncing back with SMTP Error 421 4.7.28, your IP address has been temporarily blocked - Published: 2025-03-18 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-7-28-ip-temporarily-blocked-causes-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability If your emails are suddenly bouncing back with SMTP Error 421 4. 7. 28, your IP address has been temporarily blocked by the recipient's email service provider (ESP). No email sender wants this, and all email senders want to solve this. This error typically occurs due to:Spam-like sending behavior (high volume, poor engagement, or suspicious patterns). Failed authentication checks (issues with SPF, DKIM, or DMARC). Reputation issues (your IP has been flagged due to past sending history). If ignored, a temporary block becomes a permanent blacklist, which translates into long-term damage to your sender reputation.  In this guide, we’ll explain why this happens and how to find out if your IP is flagged, along with step-by-step solutions to fix it. What is SMTP Error 421 4. 7. 28? SMTP Error 421 4. 7. 28 is a temporary block imposed by an email service provider (ESP) when your sending IP exhibits suspicious or non-compliant behavior. A 4. 7. 28 subcode indicates that the recipient’s email provider has temporarily blocked your IP address, potentially due to security concerns. While your email is not permanently rejected, this error should not be taken lightly. The receiving server has decided to pause acceptance due to potential spam risks or security concerns—and you were most likely identified as one even if you are legitimate. If this error is not addressed and it keeps happening, temporary blocks can escalate to permanent blacklisting. This can significantly impact your ability to send emails in the long run.  Common causes of SMTP Error 421 4. 7. 28Now, the SMTP Error 421 4. 7. 28 is very common, but the things that lead to it vary... . --- ### SMTP Error 550 5.5.3 – Too Many Recipients: How to Fix & Avoid It > SMTP Error 550 5.5.3 means your email provider rejected your email because there were too many recipients. - Published: 2025-03-18 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-550-5-5-3-too-many-recipients-how-to-fix-avoid-it/ - Categories: Blog - Tags: Email Deliverability Have you hit a roadblock with SMTP Error 550 5. 5. 3? You’re not alone. This error is like an invisible barrier between you and the audience, preventing your emails from arriving where they are meant to. And it’s because you’ve exceeded the limit of recipients as defined by the provider of your email service. While bulk emailing is a powerful means of outreach, encountering these restrictions can put a real dent in your workflow (and your campaign’s success). So how do you work within these boundaries without sacrificing your email game? In this guide, we’re going to explain why this error occurs and the best ways to navigate them.  However, if you are running outbound sales, marketing campaigns, or an IT infrastructure you will need to be on your toes and adopt these strategies to get emails to your target inboxes. What is SMTP Error 550 5. 5. 3 – Too Many Recipients? SMTP (Simple Mail Transfer Protocol) Error 550 5. 5. 3 means your email provider rejected your email because there were too many recipients. Think of it as an automatic safety mechanism (email service providers put these restrictions in place to reduce spam, prevent server overload and keep email security practices in check). These limits, while maddening, are designed to protect the email system from abuse, both for the sender and for the recipient. These limitations are key to understanding how to properly execute bulk emails and outreach. Let’s explore why this error happens and how different providers enforce sending limits.

Learn how to avoid spam filters, boost inbox placement, and maximize engagement. - Published: 2025-03-18 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/outlook-seed-lists-ms365-deliverability-the-battle-between-new-and-established-lists/ - Categories: Blog - Tags: Industry insights Today, ensuring your messages land in the inbox (not the spam folder) is considered a crucial business aspect. Email marketers, sales teams, and businesses rely on high email deliverability to maximize engagement, build trust, and drive conversions. However, reaching the inbox consistently is no easy feat, especially when dealing with complex email filtering systems like Microsoft 365 (MS365). Why seed lists matter in email deliverabilityUsing seed lists is a widely used strategy to gauge and improve email deliverability. These are basically lists consisting of email addresses distributed across different mailbox providers (e. g. , Outlook, Gmail, Yahoo) to help with warming up domains and improving sender reputation before launching large-scale email campaigns.  But the question remains—do all seed lists perform equally well? And more importantly, does the type of seed list used impact MS365 deliverability? The role of seed lists in email deliverabilitySeed lists serve a crucial role in improving email performance. See, even if these addresses are not real customers, they can be used to warm up the sender’s domain before engaging in a full on campaign. That way, senders’ domains are already deemed as trustworthy by various ISPs and email providers. When they execute their large-scale outreach campaigns, their emails have a larger chance of landing in the inbox. However, not all seed lists are created equal. But understanding their impact can mean the difference between a successful email campaign and one that fails due to poor inbox placement. The importance of MS365 inbox placement for sendersMicrosoft 365 (MS365) has one of the most sophisticated... --- ### SMTP Error 554 5.6.0 – Message Content Rejected: How to Fix It > SMTP Error 554 5.6.0 is one that the email sender never wants to encounter. That means an email was rejected because of content issues. - Published: 2025-03-18 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-554-5-6-0-message-content-rejected-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability Individuals and businesses rely on email for communication for countless reasons. And so it can be incredibly frustrating when your emails don’t make it to their intended target. For instance, SMTP Error 554 5. 6. 0 is one that the email sender never wants to encounter. That means an email was rejected because of content issues. The recipient’s email server has rejected the message as it violates filtering policies—such as suspected spam-like content, incorrect formatting, or unsupported attachments. For email marketers, this mistake could result in losing email outreach opportunities, decreasing engagement rates, and unnecessary time being spent developing campaigns. IT and email security teams might have trouble figuring out how come their legitimate emails are being rejected, while SaaS email providers need to ensure that their email generated on their platforms always lands in inboxes. What is SMTP Error 554 5. 6. 0? SMTP Error 554 5. 6. 0 is a permanent failure response. It indicates an email has been rejected because of content-related issues. That usually means the recipient’s email server has, upon reviewing the message, determined that it did not meet its filtering criteria and so was blocked prior to delivery. Unlike temporary errors (such as 4. x. x codes), indicates that the message was rejected outright and that it won’t even be retried. This error can be a roadblock because it prevents emails from reaching inboxes, affecting marketing campaigns, customer communication, and business functioning. Common causes of SMTP Error 554 5. 6. 0When an email is rejected due to SMTP Error 554 5. 6. 0, it’s typically because the content of the message violates the recipient’s filtering rules. Below... --- ### SMTP Error 451 4.5.0 – Mailbox Unavailable: How to Fix It > For email senders, one of the most frustrating things that can happen is messages not getting to the intended recipients. - Published: 2025-03-13 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-451-4-5-0-mailbox-unavailable-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability For email senders, one of the most frustrating things that can happen is messages not getting to the intended recipients. SMTP Error 451 4. 5. 0 – Mailbox Unavailable is one of the common SMTP errors faced by email administration and IT teams. This is a temporary failure so the recipient's mail server rejected delivery but might allow it on another attempt. But if this error is not corrected, emails may continue to bounce or messages would get stuck in the queue. What is SMTP Error 451 4. 5. 0? SMTP (Simple Mail Transfer Protocol) Error 451 4. 5. 0 means that an email server is temporarily rejecting a message because the mailbox is not available. This rejection can happen for a number of reasons, including:The recipient’s mailbox is full, or is temporarily unavailable. The email provider of the recipient is being maintained. DNS misconfigurations or authentication failures. Email rate limits or spam filtering policies blocking the message. Because this is a temporary error, if your email server supports this, it will probably attempt a retry automatically after a while. But when the problem continues, action must be taken to fix email deliverability. Why does this error matter for email deliverability? SMTP errors such as 451 4. 5. 0 can hinder workflow and tarnish sender reputation for businesses and professionals who depend on email for communication. However, when many of your emails receive this error, it may lead to lower email interaction metrics, late communication, higher bounce rates, and blacklisting risks—which are long-term issues. Common causes of SMTP Error 451 4. 5. 0Understanding the root cause is critical when attempting to resolve SMTP Error 451 4. 5. 0 –... --- ### SMTP Error 421 4.7.29 – Suspicious Activity Detected: Fixing Email Sending Issues > Picture this: You’re about to send out an important email campaign, targeting thousands of potential customers or partners. - Published: 2025-03-13 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-7-29-suspicious-activity-detected-fixing-email-sending-issues/ - Categories: Blog - Tags: Email Deliverability Picture this: You’re about to send out an important email campaign, targeting thousands of potential customers or partners. You hit “send” with absolute confidence—and are then greeted with a cryptic bounce-back message: “SMTP Error 421 4. 7. 29—Suspicious Activity Detected. ”Panic sets in. What went wrong? Why is your email suddenly being flagged? Even more importantly, how do you resolve it before your email deliverability takes a hit? The error is a red flag to email providers (such as Gmail, Outlook, Yahoo, etc. ) that things are amiss. That could be due to an unanticipated spike in emails, issues with the authentication (SPF, DKIM or DMARC failures or mismatches), or comments of spammy behavior that got credited to your domain. What can start as this temporary measure could go on to cause something worse: long term damage to your domain reputation and ability to enter inboxes in the future. But don’t fret. We’re here for you. In this guide, we’ll explain what SMTP Error 421 4. 7. 29 is, its causes, how to fix it, along with best practices to help prevent it from happening again. What is SMTP Error 421 4. 7. 29? SMTP Error 421 4. 7. 29 is a temporary email rejection due to suspicious actions from your sending domain/IP address. It serves as a protective measure taken by email providers to block spam and prevent phishing and abuse from reaching their users. This error means your emails will not be delivered. Instead, it will defer the emails temporarily. This is not a hard bounce—meaning that it is not a permanent rejection (as is the case... --- ### SMTP Error 451 4.7.23 – Email Blocked Due to SPF Failure: How to Fix It > Authentication failures resulting in blocked or bounced emails are some of the most frustrating problems that senders have to deal with - Published: 2025-03-13 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-451-4-7-23-email-blocked-due-to-spf-failure-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability Authentication failures resulting in blocked or bounced emails are some of the most frustrating problems that senders have to deal with. And yet, these events are all too common. SMTP Error 451 4. 7. 23 is one of these common mistakes that emerges when an email gets blocked due to not passing the Sender Policy Framework (SPF) check. What is SMTP Error 451 4. 7. 23? SMTP (Simple Mail Transfer Protocol) errors refer to errors encountered in the process of sending mails. SMTP Error 451 4. 7. 23 is an indication that the receiving mail server has temporarily refused the email because it could not verify that the sending server is authorized to send email from the domain. This occurs when the SPF record—one of two important DNS authentication methods—isn’t set up correctly or does not include the mail server sending out the email. SPF failures can even cause real emails to be treated as spam or phishing attempts and thus affect business communications, sales outreach, or customer engagement. Repeated SPF failures, if left unaddressed, can result in an impaired email reputation, lowering the likelihood that your emails will land in inboxes down the line. Why SPF authentication matters for email security and deliverabilitySPF is an email authentication protocol used to prevent and combat email spoofing, a technique that attackers and spammers regularly use to pretend to be mail servers belonging to trusted organizations. When an email is sent, the mail server of the recipient queries whether the sending IP sits behind the sender domain’s SPF record If the check fails, the email may be:Rejected (SMTP... --- ### SMTP vs. ESMTP: Key Differences and Why They Matter for Email Delivery > Email is a top communication tool, but behind the scenes, strict rules guide its journey to ensure safe delivery across the internet. - Published: 2025-03-13 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-vs-esmtp-key-differences-and-why-they-matter-for-email-delivery/ - Categories: Blog - Tags: Email Deliverability Email is currently one of the most widely-used forms of communication. These emails need rules to adhere to when they are sent and received to ensure safe passage across the internet. So when you send an email, it actually goes through a rigorous communication process before it can be delivered. Sure, we don’t really see this happening in front of our eyes—but it’s what happens behind the scenes. SMTP (Simple Mail Transfer Protocol) and ESMTP (Extended SMTP) are the two most popular email protocols that determine the way these messages are sent, received, and processed, SMTP has been the standard protocol since the early days of the internet, and ESMTP is essentially an extension or an upgrade that provides added capabilities such as authentication, encryption and improved error handling. For certain businesses, depending on how vital email is to their communications, marketing or transactional needs, understanding how SMTP and ESMTP are different from each other may have lasting effects on the business. This article explains how these protocols work, the reasons why ESMTP is an enhancement over the earlier SMTP, and the advantages of ESMTP implementation to improve the email experience. What is SMTP? It is the standard communication protocol used for sending emails over the Internet. It is in charge of managing the exchange of emails between both mail servers and email clients. SMTP works in a command and response way, wherein the sending server sends a command to the receiving server and waits for the response before issuing the next... --- ### Email Warmup Alternatives: When Traditional Warmup Isn’t Enough > Cold email outreach is a powerful weapon for businesses, but it only works if you can ensure email deliverability - Published: 2025-03-10 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/email-warmup-alternatives-when-traditional-warmup-isnt-enough/ - Categories: Blog - Tags: Email Deliverability Cold email outreach is a powerful weapon for businesses, but it only works if you can ensure email deliverability—that is, the ability to hit the inbox rather than go to spam. Email warmup is one of the most critical steps in achieving high deliverability. It's the practice of gradually increasing the volume of emails sent from your mail server so that email providers build a positive impression of you as a sender. If your business is on a new domain, changing to a new email service provider, or running cold outreach campaigns, then you need to warm up to avoid being flagged as spam.   Sending thousands of emails at once from the domains can raise a red flag from ESPs and such emails may get blocked. Hence, traditional warmup methods were introduced—automated interactions where emails are sent and opened create a semblance of organic engagement. While this approach helps, it often falls short due to other factors like spam filters, low engagement rates, inconsistent inbox placements, and domain reputation issues. In a sense, you can say that traditional warmup methods are surface-level only. In this article, we’ll explore Warmy’s email seed list as an alternative, how it compares to traditional warmup, and how to use a seed list as an email warmup alternative. What is traditional email warmup? Traditional email warmup is the process of gradually increasing the volume of emails sent from a new or inactive email account to establish a positive sender reputation with email service providers (ESPs) like Gmail, Outlook, and Yahoo. This... --- ### Email Engagement How Seed List Helps Improve Open & Click Rates > It is easy for Internet Service Providers (ISPs) — such as Gmail, Yahoo, and Outlook to categorize your messages as spam - Published: 2025-03-10 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/email-engagement-how-seed-list-helps-improve-open-click-rates/ - Categories: Blog - Tags: Email Deliverability It is easy for Internet Service Providers (ISPs) — such as Gmail, Yahoo, and Outlook to categorize your messages as spam or a simple promotional clutter, especially if you have a new or inactive email account. For email marketers, this can be a nightmare. The reason for this ISPs does not have any foundational information about your account, hence, if they noticed that you sent a bulk email with a newly created account, they may consider your account and your email messages spammable. But how can you resolve this? Email engagement holds great significance in establishing sender reputation and securing email deliverability, which is why email warmups in cold outreach are considered as a necessary marketing advantage.  Low engagement can negatively impact inbox placement, ultimately reducing conversions and campaign effectiveness, and are one of the reasons why your emails are being routed to spam. One effective way to enhance email engagement and increase open and click-through rates is by leveraging a seed list.  In this article, we explain the traditional essence of what an email seed list is and explain how Warmy developed a more innovative approach of taking email seed lists to higher levels for warming up emails, and improving its reputation from different email providers. What is a Seed List? A seed list consists of test email addresses distributed from different email service providers and ISPs. It supplies a controlled testing environment, for an effective analysis of inbox placement, understanding of sender reputation and measurement of engagement performance, before the actual launch of an email campaign... --- ### Google Postmaster Issues Fixing Bad IP & Domain Reputation > A decline in the sender’s IP or domain reputation is most likely the reason why their emails are going to junk or spam - Published: 2025-03-07 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/google-postmaster-issues-fixing-bad-ip-domain-reputation/ - Categories: Blog - Tags: Email Deliverability A decline in the sender’s IP or domain reputation is most likely the reason why their emails are going to junk or spam, which can result in an equal decline in open rates.  There are, of course, a number of practical strategies to improve your open rates.  The use of Google Postmaster tools offers valuable insights into your sender's reputation. This advantage is required by many email users to ensure high email deliverability. However, many email marketers struggle to interpret and act on this data effectively. Leveraging seed list testing is a powerful strategy for diagnosing and fixing deliverability issues. It uses a controlled test environment, allowing businesses to pinpoint any deliverability problems before they escalate into something they cannot resolve.  In this article, we will explore how to diagnose and resolve bad IP and domain reputation issues using Google Postmaster Tools, with a specific focus on how seed list testing can help businesses monitor and improve email deliverability. Understanding Google Postmaster ToolsGoogle Postmaster Tools is a free platform that provides email senders with valuable analytics related to their email performance on Gmail.

If you do it correctly, it will return miracles to your business. However, if done incorrectly, can have a very bad effect on your business.  As an email sender, there are various issues that you can come across and one of the common errors is SMTP Error 421 4. 7. 0 – Temporary Email Rejection. It's a policy-based, temporary rejection of an email server. Although this rejection is not permanent, multiple rejections can adversely affect sender reputation and ultimately—long-term deliverability of emails. So if your emails are getting temporarily rejected, it’s a sign that something is wrong and you need to address this issue early. What is SMTP Error 421 4. 7. 0? SMTP Error 421 4. 7. 0 is a temporary email rejecting error. Unlike a hard bounce, when an email cannot be delivered permanently (for instance, because the address being sent to is invalid), this error means that the recipient’s mail server has temporarily blocked the delivery of the message, but may allow safe passage to go through later. How SMTP Error 421 4. 7. 0 affects email deliverabilitySMTP Error 421 4. 7. 0 is a temporary rejection that can have a long-term impact on your email deliverability and sender reputation. Let’s explore how this error affects your email performance — and what it means for your overall deliverability strategy.

It doesn’t matter if you are sending cold emails, marketing campaigns, or transactional messages—they all rely on a few elements to ensure that they actually land in the inbox and not the spam folder. This is where DNS email authentication protocols come into play—SPF, DKIM, and DMARC—these three have a crucial role in proving the legitimacy of your messages. But how much do DNS configurations really impact deliverability? And does even the type of email template you use (plain text vs. HTML) affect your inbox placement? Warmy’s research team set out to answer these questions by conducting a rigorous and data-driven experiment. We analyzed email deliverability data by testing real-world scenarios with different DNS setups and email content formats. Understanding the core DNS records: SPF, DKIM, and DMARC DNS (Domain Name System) records act as the internet’s address book. It is responsible for converting domain names to IP addresses and controlling different domain-related issues and settings. For example: When it comes to email deliverability, the DNS records allow mail servers to verify if an email originated from a trusted sender. A well-configured set of DNS records (SPF, DKIM, and DMARC) minimizes the risk of spoofing, phishing attacks, and spam classification, which means your emails are more likely to land in the inbox. With that said, if you do not specify the right DNS records, even legitimate emails can be delivered in the spam folder. That’s also why... --- ### SPF Alignment Issues: Causes, Fixes & Best Practices for Better Email Authentication > Crazy to think what happens when you hit "Send"—your email races through networks, security checks & spam filters in seconds! - Published: 2025-03-05 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/spf-alignment-issues-causes-fixes-best-practices-for-better-email-authentication/ - Categories: Blog - Tags: Email Deliverability It’s mind-blowing sometimes to think about everything that goes on behind the scenes when you click on “Send” after writing an email. In seconds, your message goes on a complex journey—getting relayed over networks, through authentication checkpoints, and under multiple security layers before it arrives in your recipient’s inbox (or, if luck’s not in your favor, their spam folder). SPF (Sender Policy Framework) is an important authentication protocol used to make sure that your email arrives safely. Designed to prevent spoofing and phishing, SPF enables mail servers to check whether an email originated from an authorized source. But SPF alone is not immutable and it must be properly aligned with the sender’s domain in order to truly work. SPF record configuration issues, alignment mismatch issues, third-party sending services, and other issues can cause rejection, spam filtering, and deliverability nightmares. This is why SPF alignment issues should matter to IT administrators, email security experts, and marketers who use email in their business growth and communication. What is SPF alignment? SPF alignment means that the domain used in the Return-Path (also called the "envelope-from" or "MailFrom" domain) matches the domain in the From address that the recipient sees in their inbox. If these domains are the same or share the same root domain (depending on the alignment mode), SPF alignment passes. If they are different, SPF alignment fails, which can affect DMARC authentication and potentially result in emails being rejected or marked as spam. How SPF alignment worksWhen an email is sent, the recipient’s mail server checks the SPF record... --- ### SMTP Error 451 4.7.26 – Email Blocked Due to Poor Domain Reputation > Email deliverability is essential to any effective email marketing or transactional email plan.

This, in turn, leads to temporary blocks and poor deliverability.  In this guide, we’ll take a look at what causes this SMTP error, how domain reputation affects your email deliverability, and the actions you should take to troubleshoot and recover from it. What is SMTP Email Error 451 4. 7. 26? SMTP Error 451 4. 7. 26 is an email server temporary rejection due to bad domain reputation. This usually means that the recipient’s mail server has flagged your domain as suspicious, untrustworthy, or likely to send spam. There are several reasons for it, and knowing those can help you identify the problem and resolve it. It’s similar to your email being your passport and the receiving email provider being the Immigration Control. They consider you shady or questionable—and stop you from crossing. To resolve the issue, you need to establish trust to make your domain reputable. This is a common problem with all large mail service providers, such as Gmail, Yahoo, and Outlook, which have advanced filters that decide whether an email gets delivered to inboxes, sent to spam, or rejected entirely.  If you’re composing an email and you receive an error message similar to the one pictured below, your domain reputation may have been compromised:451 4. 7. 26 Mail not accepted due to poor domain reputation.

No warning, no real explanation—just an obscure bounce message: “SMTP Error 451 4. 7. 24 – DMARC Policy Failure. ”If this is starting to sound familiar, you’re not alone. A lot of businesses and email marketers struggle with this annoying error without being able to fully comprehend why their emails are not accepted. In this article, we’ll explain what SMTP 451 4. 7. 24 means, why DMARC failures cause email rejection, as well as how to resolve them so your emails find their way into inboxes instead of spam folders. What is SMTP Error 451? SMTP (Simple Mail Transfer Protocol) is a set of rules that servers follow to send and receive messages. But when things go wrong—especially with security authentication—your email server may respond with an SMTP 451 error indicating a temporary rejection. The 4. 7. 24 error code is a special case that indicates a DMARC (Domain-based Message Authentication, Reporting, and Conformance) policy failure, which means your email failed an authentication check. What is DMARC and why is it important? Now more than ever, email security is vital. Cybercriminals leverage email vulnerabilities to impersonate businesses, send phishing emails and commit fraud daily. This is where DMARC steps in. It isn’t just another email security protocol. It’s a policy layer that ensures only legitimate emails sent from your domain reach inboxes. attackers can send... --- ### SMTP STARTTLS Errors Causes, Fixes & How to Ensure Secure Email Communication > eing exposed to email security risks is something we all want to avoid; security risks such as man-in-the-middle (MITM) attacks - Published: 2025-03-05 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-starttls-errors-causes-fixes-how-to-ensure-secure-email-communication/ - Categories: Blog - Tags: Email Deliverability Being exposed to email security risks is something we all want to avoid; security risks such as man-in-the-middle (MITM) attacks, where attackers intercept and manipulate email traffic, are the bane of all email marketer’s existence.  There are the basics of ensuring a configured DNS and SMTP setting, but some errors go deeper than that.  Some email users receive errors such as:Authentication failure An error that stemmed from when an email client or server fails to establish a secure TLS connection — a security protocol that preserves privacy and data security.  Conducting an email deliverability test is a contributing factor allowing email users to perform proper evaluation and avoid some common and complex errors that are affecting their email deliverability.  However, we at Warmy. io understand that it would take a lot more to avoid such errors, which is why we’ve developed a variety of tools to improve the overall email process. But first, let us understand what STARTTL is, and what are its repercussions that affect your overall email experience? What is STARTTLS? STARTTLS is used to upgrade a plain-text email connection to a secure, encrypted connection using TLS (Transport Layer Security). It is a protocol common that helps boost email security by preventing unauthorized access to transmitted messages. STARTTLS works by:Connecting an email client to an SMTP server via an unencrypted connection.  The client issues the STARTTLS command, requesting encryption. If the server supports TLS, it upgrades the connection to a secure one. Emails are transmitted securely, preventing data interception. STARTTLS ensures confidentiality and... --- ### SMTP Error 421 4.7.26 – Email Rate Limit Exceeded: Causes & Fixes > Sending limits and anti-spam measures are being imposed by Internet Service Providers (ISPs) and Email Service Providers - Published: 2025-03-05 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-7-26-email-rate-limit-exceeded-causes-fixes/ - Categories: Blog - Tags: Email Deliverability Ensuring that your emails land in recipients’ inboxes is getting more and more complex. Sending limits and anti-spam measures are being imposed by Internet Service Providers (ISPs) and Email Service Providers (ESPs) to prevent unwanted emails from reaching users. As a result, errors sometimes occur for even legitimate senders—affecting their email campaigns. The SMTP Error 421 4. 7. 26, for instance, is a widely supported code from many email servers when a rate limit has been reached and messages are temporarily rejected. This happens most commonly when the sender sends many emails to many recipients in a short period of time, which in turn activates throttling mechanisms designed to prevent spam. Nevertheless, if not managed properly, it can have a massive impact on email deliverability, campaign performance, and sender reputation. What is SMTP Error 421 4. 7. 26 and what does it mean? SMTP Error 421 4. 7. 26. indicates that the recipient’s email server has temporarily refused messages because the sender has hit sending rate limits. So actually SMTP 421 is a temporary error code, which indicates the server has rejected the message but the sender can try later. Whereas permanent errors (5xx errors) indicate that the email cannot be delivered, 421 errors do not—they just mean that the server cannot take a message at this moment or that it is applying restrictions. A typical 421 error message may look like this:CopyEdit421 4. 7. 26 – Email rate limit exceeded, try again later.

In the realms of email marketing the technical aspects are just as crucial as the marketing ploy; our research team devoted their time to understanding the best and most helpful technical factors that can help every email user and marketer with the ability to achieve the best email deliverability and reputation. For this research, our team examined how different warm-up strategies affect the deliverability of emails from newly created domains. We’ve tested various flows, each focusing on different approaches that includes: Gradual and moderate volume increases Passive engagement Content diversification Mailbox redirect assessment Delayed sending Platform-specific warm-ups, Platform diversity testing Our objective is to determine the best practice for optimizing domain reputation and ensure high deliverability rates. A Deeper Look Into Our Research’s Objectives  One of the many reasons why your emails are probably going to spam or junk is because you have a new email or domain. Many Internet Service Providers (ISPs) may have an issue with new or inactive email addresses when it comes to sending bulk, or large quantities of emails. ISPs do not have any established data for new domains and inactive mailboxes, so when these new or inactive emails send a large number of messages there is a large chance that it may direct their message to spam. Email warmup is, therefore, crucial in establishing a trustworthy sender reputation before large-scale outreach. What We Did and... --- ### How SMTP AUTH Mechanisms Affect Email Deliverability and Security > Having Warmy as your overall email deliverability system can provide you with the capability to configure your SMTP setting - Published: 2025-02-28 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/how-smtp-auth-mechanisms-affect-email-deliverability-and-security/ - Categories: Blog - Tags: Email Deliverability SMTP Authentication (SMTP AUTH)  is not only a fundamental mechanism that protects your emails against spoofing and phishing attacks. It also has a direct contribution to your email deliverability and brand recognition.  Depending on how well you set up your SMTP AUTH you are less likely to experience SMTP errors related to authentication failures —potentially SMTP Email Error 500 5. 7. 1—, email bounces, and poor inbox placements.  However, proper SMTP configuration is easier said than done. Having Warmy as your overall email deliverability system can provide you with the capability to configure your SMTP setting, besides on its well-known features, such as its free email deliverability test. For this blog, we will take a deep examination of SMTP AUTH and what exactly is its contribution to email deliverability and the improvement of email security? Explaining the Essence of SMTP AUTHBefore sending messages, email clients need to undergo an authentication process with the mail server, to ensure that only the authorized users can send emails from specific domains.  This extended protocol is known as SMTP AUTH and its process involves the following steps:The email client initiates an SMTP session with the mail server. The client provides authentication credentials or a token. The server verifies the credentials and grants access. The email is sent securely if authentication is successful, preventing unauthorized senders from using the mail server. It prevents unauthorized access, that prevents email spoofing, secure your email account against unauthorized access, and ensure that your reputation is protected. It also provides the following benefits such as:Prevention of Email Spoofing: Minimize impersonation... --- ### SMTP Error 421 4.3.2 – Service Shutting Down Causes & How to Fix It > One of these temporary errors is the SMTP error 421 4.3.2 (Service Shutting Down), an incident where a mail server unexpectedly closes down. - Published: 2025-02-28 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-3-2-service-shutting-down-causes-how-to-fix-it/ - Categories: Blog - Tags: Email Deliverability There are tons of SMTP related errors that an average email user can encounter. Some of them can be due to IP reputation concerns, while others are rooted and are likely the result of a temporary errors failure — retryable errors.  One of these temporary errors is the SMTP error 421 4. 3. 2 (Service Shutting Down), an incident where a mail server unexpectedly closes down. Encountering this, of course, will result in email delivery interruptions, but it is highly unlikely that the issue is caused on your end.  This issue can stem from server overload or scheduled maintenance. However, there are some instances in which this error occurs due to a misconfigured setting that prevents emails from being processed. Understanding the cause of this error is the first step. Although you are receiving this error from a server overload, you cannot neglect other factors that may affect your email deliverability.  In this guide, we’ll explain what SMTP error code 4. 3. 2 is, its impact on email servers, how to fix it, and what are some of the best practices to prevent future occurrences. What Causes This Issue? SMTP error 421 4. 3. 2 – Service Shutting Down typically indicates a temporary failure on the mail server. This means that the error is a result of uncontrollable factors such as mail server overloads, or scheduled maintenance.  However, you can still receive this error message if there are some sending limitations implemented in your account, or your email is blacklisted. Here are the detailed explanations of this issue.  Mail Server OverloadThe mail server is... --- ### SMTP Connection Encryption: The Key to Secure & Reliable Email Delivery > One of the top channels of communication for businesses is email, which unfortunately makes it one of the prime targets of cyberthreats like phishing - Published: 2025-02-28 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-connection-encryption-the-key-to-secure-reliable-email-delivery/ - Categories: Blog - Tags: Email Deliverability One of the top channels of communication for businesses is email, which unfortunately makes it one of the prime targets of cyberthreats like phishing, data interception, and spoofing. Encryption is the answer. Without it, emails are transmitted as plaintext over the Internet where people can steal sensitive information.  SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails, but it is not secure by default. To protect email communications, SMTP encryption is essential. In this blog, you will learn how SMTP encryption works, the difference between TLS and SSL, and best practices to help you achieve email security. What is SMTP and why it needs encryptionSMTP is the protocol that does the heavy lifting when it comes to routing an email from the sender’s email server to the intended recipient’s inbox. But SMTP only makes sure that emails get delivered, it does not offer security by default. SMTP is based on the client-server model, where the sending mail server is the client, and the receiving mail server is the server.  It uses commands and responses, like HELO, MAIL FROM, and RCPT TO. There is no default encryption built into Simple Mail Transfer Protocol (SMTP), meaning that attackers are able to intercept, alter and spoof SMTP messages.  To secure this process, encryption mechanisms are being used such as TLS (Transport Layer Security) and SSL (Secure Sockets Layer). SMTP sends emails in plaintext by default, which is its biggest disadvantage, as it is prone to many security threats, such as: Man-in-the-Middle (MITM) Attacks: Cybercriminals can intercept your emails while in transit, modifying or... --- ### SMTP Error 421 4.4.1 – No Answer from Host: What It Means & How to Fix It > The SMTP Error 421 4.4.1 – No Answer from Host error indicates that your email server is unable to connect with the recipient’s server. - Published: 2025-02-26 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-error-421-4-4-1-no-answer-from-host-what-it-means-how-to-fix-it/ - Categories: Blog - Tags: Marketing The SMTP Error 421 4. 4. 1 – No Answer from Host error indicates that your email server is unable to connect with the recipient’s server.  This is just one of the many problems that can deeply affect email deliverability resulting in delays or even undelivered messages. So what should an email sender do when this message shows up?  In this guide, we’ll explain why this error happens, what you can do to fix it, and the best practices to avoid it in the future. What causes SMTP Email Error 421 4. 4. 1? It is a specific form of the SMTP Email Error 421. It happens when the server that sent the email tries to connect with the email server of the receiver but does not get a response. The reasons can be any of the following:Network connectivity issuesEmails need stable networks and temporary problems of weak networks may lead to SMTP Email Error 421 4. 4. 1. The connection could be blocked for security policies, wrong firewall settings, etc. Moreover, when the sender's server suffers from DNS resolution failures (when a DNS server fails to resolve a domain name to the associated IP address), it will also fail to connect. Recipient mail server issuesIf the receiving mail server is down, then the sending mail server fails to create a connection. The recipient’s email server could be down for maintenance or an outage. If it has a high number of concurrent requests, the receiving mail server may not be able to respond as well. Sender-side problemsIf the sender’s IP is on spam blacklists, the recipient’s server... --- ### SMTP Retries and Deferrals: Understanding Email Delays & How to Fix Them > The main protocol for sending email is the Simple Mail Transfer Protocol (SMTP), which manages both the sending - Published: 2025-02-26 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-retries-and-deferrals-understanding-email-delays-how-to-fix-them/ - Categories: Blog - Tags: Email Deliverability The main protocol for sending email is the Simple Mail Transfer Protocol (SMTP), which manages both the sending and routing of messages between networked devices. But the journey from sender to recipient can sometimes be rocky. This may also result in SMTP retries/deferred by the senders. Though these mechanisms are supposed to be able to deal with transient delivery problems, they can cause noticeable (and frustrating) delays from time to time. SMTP retries come into play if an email encounters a temporary failure—like server congestion or network problems. These cause the system to retry to deliver the message at a later interval. Likewise, deferrals place an email on hold in a queue, until the right conditions have been met and it’s pushed through. In this guide, we’ll break down how these SMTP processes operate, what commonly causes them and their effect on deliverability. So whether you work as an IT administrator, email deliverability expert, network engineer, or as part of a marketing team that manages bulk emails, knowing these dynamics will help to make sure that your communications reach where you plan to send. What are SMTP retries and SMTP deferrals? SMTP retries and deferrals are built-in mechanisms implemented to smoothen out temporary problems in email delivery. Retries and deferrals are both critical for maintaining email reliability and ensuring that messages are not lost forever when conditions are less than ideal. SMTP retries: If an email does not reach its destination on the first attempt, the sending server does not classify it as a permanent failure. Rather, it starts a round... --- ### Fixing Reverse DNS Lookup Failures Best Practices for Email Server Configuration > Email is an instrumental communication tool that finds its advantages in areas such as marketing, customer support. - Published: 2025-02-26 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/fixing-reverse-dns-lookup-failures-best-practices-for-email-server-configuration/ - Categories: Blog - Tags: Marketing Email is an instrumental communication tool that finds its advantages in areas such as marketing, customer support, and other internal communication processes.  Email marketing is considered as the “king of all marketing channels”, while email communication for both customer support and internal communication offers a non-time sensitive system allowing everyone without rushing too much of the information. Here at Warmy. io, we understand the immense value of emails for almost everyone in the professional landscape; giving us the opportunity to implement an All-In-One tool for email deliverability. With our boundless offerings of free tools such as our free email deliverability test. However, we also understand that there are a variety of factors that may affect your email deliverability. When an email user consistently gets their emails marked as spam, gets rejected by mail servers, or when you understand that your email reputation is suddenly depleting then it is most likely the cause of a Reverse DNS (rDNS) lookup failure.  Reverse DNS helps email servers verify that the sending server’s IP address resolves to a legitimate domain. When this verification fails, mail servers may reject emails, flag them as spam, or lower your sender reputation, impacting your ability to reach inboxes. Explaining Reverse DNS Lookup and its ImportancerDNS lookup is a procedure that involves mapping an IP address back to its associated domain name. It is a verification process utilized by mail servers to guarantee that the genesis of the email is legitimate and from a trusted source. Simply put, it helps you identify the domain name... --- ### SMTP AUTH Mechanisms Explained Choosing the Right Authentication for Secure Email Sending > SMTP AUTH mechanisms explained: Learn how to choose the right authentication method for secure and reliable email sending. - Published: 2025-02-26 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-auth-mechanisms-explained-choosing-the-right-authentication-for-secure-email-sending/ - Categories: Blog - Tags: Marketing Phishing attacks, and spam emails remain a continuous problem for many email users. One of the most notorious forms of email security issue is the unauthorized access or usage of a bad actor or a spammer towards an email.  If this ever happened to you then that means that you probably have an issue with your SMTP authentication (SMTP AUTH). SMTP Authentication is an important mechanism guaranteeing that the only authorized users can send emails through the mail servers, prevents unauthorized use and maximizes email deliverability.  Improving your overall email deliverability is the lifeblood of our workforce here at Warmy, our services is not limited to our free email deliverability test, our users can also take advantage of our free SPF Record Generator that can help specify which mail servers have the authority to send emails for a specific domain.

Understanding SMTP Authentication: How It Works and Its ImportanceSMTP (Simple Mail Transfer Protocol) is used for email transmission, therefore making it a standard communication protocol. Here is how it goes. Upon sending an email, the SMTP client communicates with the SMTP server then forwards the message to the recipient’s mail server. Without any form of authentication, malicious actors could exploit SMTP servers to send spam emails. Thus, making SMTP authentication a requirement for email users. It verifies credentials before... --- ### Reverse DNS Lookup Failures How They Impact Email Deliverability and Sender Trust > Email drives the highest ROI, making inbox placement & deliverability a top priority for businesses & marketers. - Published: 2025-02-25 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/reverse-dns-lookup-failures-how-they-impact-email-deliverability-and-sender-trust/ - Categories: Blog - Tags: Email Deliverability Email is a valuable communication channel, especially for many businesses and email marketers. It is known to develop the highest ROI, which should make inbox placement and email deliverability a priority.   The capability to ensure that your emails are delivered to the intended recipient is a simple idea, yet there are still some email users in fact a study showed that out of 1000 email users 39% of them rarely or never conduct email list hygiene. One of the basic, yet crucial aspects in the improvement of the email deliverability process are implementing email authentication protocols, such as the Reverse DNS (rDNS) lookup.  rDNS lookup is an instrumental authentication system that helps establish trust between mail servers. Its main function involves verifying the legitimacy of email senders, it is a process that involves the confirmation if an IP address sends an email correctly maps back to a domain name.  However, when reverse DNS lookup fails, there are associated consequences that may get involved in your capabilities in using your emails. Consequences that will result into your emails getting:RejectedBeing flagged as spam Suffering from poor email deliverabilityHaving these can damage your reputation making it more challenging for email marketers and other businesses to interact and reach their audiences effectively. Explaining Reverse DNS (rDNS) LookupReverse DNS (rDNS) lookup is the process of resolving an IP address to a domain name. This is the opposite of the standard DNS lookup, which maps a domain name to an IP address. How Reverse DNS WorksIt all starts when an email is sent. The... --- ### Why SSL & TLS Certificate Errors Are Hurting Your Email Deliverability > Email marketers know a proper email & domain setup is key, but SSL/TLS errors can still impact deliverability & sender reputation. - Published: 2025-02-25 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/why-ssl-tls-certificate-errors-are-hurting-your-email-deliverability/ - Categories: Blog - Tags: Marketing If you are an email marketer, you probably understand that having the best email and domain setup are one of the fundamentals to ensure that you have a functioning email. However, one factor that can still affect your email deliverability and overall reputation are errors caused by SSL (Secure Sockets Layer) and TLS (Transport Layer Security) certificates. SSL and TLS are digital signatures used for allowing systems to verify and establish an encrypted network connection, any form of misconfigurations, expirations or error in its validation can cause email messages to be blocked, flagged as spam, or rejected.  As an All-in-One tool for email deliverability, we at Warmy. io understand that securing email communications is an instrumental part of maintaining a reputable email domain, and these two protocols are critical for securing email transmissions.  Let’s take a look at the following best practices for maintaining a secure email communication, and what are the additional factors you should consider to prevent authentication failures and compromise your email performance. Protecting Emails With SSL & TLS CertificatesSSL and TLS certificates are cryptographic protocols used for encrypting email communications and securing every transmitted data between mail services and recipients.  They are used to authenticate the sender’s identity and contribute to the security of network connection preventing unauthorized access, interception, or manipulation of emails.  Contribution of SSL/TLS in Email CommunicationSSL/TLS are crucial components that ensure security of your email communications. It warrants the following contributions:Encryption: Avoid email data from being intercepted by malicious parties and actorsAuthentication: Confirms if the email senders are legitimate,... --- ### Maximizing Email Deliverability: Grouped vs. Randomized Sending > Many emails land in spam due to poor sending practices. Warmy’s research helps ensure your emails reach inboxes, not junk folders. - Published: 2025-02-24 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/maximizing-email-deliverability-grouped-vs-randomized-sending/ - Categories: Blog - Tags: Industry insights Many organizations suffer the pain of emails ending up in spam folders or being throttled—often because sending practices are widely inconsistent with Outlook 365’s spam filters. At Warmy, our research team continues to do more by figuring out how to get more of your emails delivered, straight to your intended inbox. Our ongoing testing and analysis will enable you to avoid typical email-sending mistakes that make outreach wasteful for businesses. It’s a fact: Every email counts, and even minor missteps in sending strategy can have a significant impact. That's why we recently conducted an in-depth experiment comparing two distinct methods: grouped sending versus randomized sending. What does sending strategy have to do with email deliverability? It is not only the quality of the content that decides email deliverability. It’s also very much connected to the way you send your emails. How you distribute your messages can have a major impact on whether or not your email hits the inbox or the spam folder. Of course, it’s not the only factor, but it does have an impact. Different sending strategies send different signals to email service providers: For instance, sending a bunch of emails at once, or all at the same time, could initiate “bulk spam activity” and trigger spam filters. Conversely, a more randomized sending approach could well resemble natural user behavior, possibly reducing the chances of being considered spam. So, which approach is more effective? And how much does email-sending strategy really influence deliverability? In our experiment, we put these two methods to... --- ### SSL and TLS Certificate Errors in Email Servers: How They Impact Deliverability > SSL/TLS encrypts email traffic & verifies servers, but misconfigured certificates can break security. - Published: 2025-02-24 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/ssl-and-tls-certificate-errors-in-email-servers-how-they-impact-deliverability/ - Categories: Blog - Tags: Marketing What if you were to send an important email—a client proposal, let’s say, or a security update, or internal memo—and it was rejected, marked as spam, or even intercepted? That’s where SSL/TLS encryption comes in. These protocols secure email traffic through data encryption and confirmation of the authenticity of mail servers. But SSL/TLS encryption doesn’t work if the certificates are misconfigured. Expired certificates, mismatches, or weak encryption protocols can cause mail delivery failures, reduce sender trust, and even expose emails to attackers. Understanding SSL & TLS in email security Emails, without encryption, are subject to eavesdropping, modification, or even phishing. SSL SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols that protect the transfer of emails while passing through the internet. What is SSL/TLS? SSL and TLS are protocols that secure the message communication between email clients (Outlook, Thunderbird etc) and mail servers. This means sensitive information—like login credentials, financial information and private messages—is safeguarded from being viewed by anyone else without your consent. TLS is the successor of SSL TLS 1. 2 TLS 1. 3 are the current security standards Older versions (SSL 3. 0, TLS 1. 0 and TLS 1. 1) are now deprecated Because secure email delivery plays a key role in the services provided by email providers and ISPs may require TLS encryption during email exchange. How does SSL/TLS encryption secure email communication? Confidentiality: Ensures that no unauthorized third parties can intercept and read your emails. Authentication: Ensures that the correct mail server is communicating with the correct sender and receiver Data integrity: Prevents the... --- ### The Challenges of SMTP over IPv6: What You Need to Know Before Transitioning > IPv4 exhaustion is driving businesses to SMTP over IPv6 for infinite addresses, better routing & scalability without network limits. - Published: 2025-02-24 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/the-challenges-of-smtp-over-ipv6-what-you-need-to-know-before-transitioning/ - Categories: Blog - Tags: Marketing SMTP (Simple Mail Transfer Protocol) has been the staple of email communication for the last couple of decades—forwarding messages over networks via the Internet Protocol, which has, until recently, been IPv4.  But exhaustion of IPv4 addresses is gradually pushing businesses and email service providers to think about moving to SMTP over IPv6. It provides a nearly infinite address space, more efficient routing, and enhanced support for modern infrastructure. Such a transition is critical for long-term scalability, as it guarantees that email systems can expand over time without facing address exhaustion or network constraints. While there are advantages in making the switch to SMTP over IPv6, there are also major hurdles that organisations have to scale. In this post, we’ll dive into those challenges and offer actionable steps you can take to facilitate a smooth transition with good email deliverability rates. Understanding SMTP over IPv6IPv4 (Internet Protocol version 4) is the original building block of the internet and provides roughly 4. 3 billion unique IP addresses. This was sufficient back in the internet’s early days, but the proliferation of the internet of things, services, and cloud computing quickly drained the available addressable IPv4 space. Because of this, IPv6 was created, allowing networks and services in all their forms (including email servers) to continue growing as needed, indefinitely. IPv6 for networking and scalability: key benefitsPractically unlimited addresses since IPv6 supports 340 undecillion addresses, and there is no shortage. Better routing efficiency because it optimizes usage of NAT (Network Address Translation) and eases the network configuration. The built-in IPSec (Internet Protocol Security) adds better encryption and authentication. Natively supports modern... --- ### SMTP over IPv6: The Future of Email Servers and What It Means for Deliverability > IPv4, the internet’s original addressing method, only has a limited number of unique addresses about 4.3 billion. - Published: 2025-02-21 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/smtp-over-ipv6-the-future-of-email-servers-and-what-it-means-for-deliverability/ - Categories: Blog - Tags: Email Deliverability The Simple Mail Transfer Protocol (SMTP)’s primary role is to make sure messages take the right path from senders to recipients. But with the world reeling with the internet boom, the traditional IPv4 system reached a point where it could no longer keep up. IPv4, the internet’s original addressing method, only has a limited number of unique addresses (about 4. 3 billion). The reality is, this felt like a deep pool once—decades ago. But nowadays, IPv4 addresses are quite depleted. Enter IPv6—which provides an almost limitless number of IP addresses, better security, and more efficient routing. However, the adoption of SMTP over IPv6 presents both opportunities and challenges and understanding this shift is crucial for staying ahead in the evolving email landscape. What is IPv6 and how does it differ from IPv4?  IPv4 was the king of protocols since the dawn of the internet.

Emails may go unnoticed among the others in the inboxes. Then there are phishing and spoofing attempts. And yes, the infamous spam folder and a thousand other challenges that businesses tackle every day.  BIMI (Brand Indicators for Message Identification) overviewEnter BIMI (Brand Indicators for Message Identification). It is an email authentication standard that lets businesses show their official logo next to email messages in recipients’ inboxes. It also works with standard protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). If an email meets all BIMI requirements, it will show the brand’s logo instead of the default avatar or initial. Here’s a breakdown of its other important advantages: Enhanced brand visibility: Your company’s logo shows up in inboxes, making sure that you maintain brand image and that your branding is uniform.  Increased email trust: Recipients are more likely to have trust in emails that show the brand from which they come.  Enhanced email deliverability: Since BIMI helps create a trusted brand presence in an inbox, it is less likely that a serious email from a company will land in the spam folder. 4 ways implementing BIMI boosts brand recognitionThe average office worker receives 121 emails per day. So it’s really difficult for businesses to stand out. Implementing BIMI is a game-changer in this regard since it gives brands a solution to be recognizable in a full inbox.

Can you believe it? And this 2025, it is estimated to be 376. 4 billion. The point is, you cannot make sure your email is seen, much less read. Assuming your email gets to the inbox at all, and there’s no guarantees of that either. That is where BIMI (Brand Indicators for Message Identification) can help.  In this article we will cover how BIMI works, why you should implement BIMI for your brand and how implementation works. What is BIMI? BIMI allows you to display your brand’s logo next to your email messages. This enhances the legitimacy of emails and their parent brands and strengthens security protocols. The evolution of email authenticationAs email became ingrained in human communication, its usage grew along with threats to security. Back then, anyone could basically send an email pretending to be someone else.  Phishing and spoofing attacks surged—leading to monetary losses across the world. Business email compromise (BEC) alone was faced by 64% of businesses averaging a loss of $150,000 per incident. Experts developed authentication protocols including SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). These protocols worked magic behind the scenes but did little when it came to allowing recipients to visually attest whether an email was legit and coming from a reputable source.

Take a minute to think back to the moment leading up to the actual purchase. What did you do first? Chances are, you talked to people who made similar purchases. But knowing that someone bought the same thing (and is happy with their decision) is almost guaranteed to drastically increase your likelihood of doing so too. So how do you use this information? You can’t sit around and hope all prospects will consult your past and current clients in order to buy from you. Instead, what you can do is leverage social proof in your cold outreach to build trust with potential clients. What is social proof? Social proof is a term that comes from Consumer Psychology. Put simply, it means that you provide proof that your clients are satisfied. These are reviews, case studies, client testimonials, etc. In this article, we’ll cover all the different methods you can leverage social proof within your cold outreach strategy for driving your sales.

For rare and unusual circumstances these can take up to 72 hours. - Published: 2025-02-12 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/what-is-dns-propagation-and-how-to-minimize-its-impact-on-email-deliverability/ - Categories: Blog - Tags: Email Deliverability DNS records undergo modifications — such as SPF, DKIM, DMARC, MX, A records, or PTR records. These updates or modifications should propagate across global DNS servers, caching information a certain period before it refreshes.  These modifications should not take longer than a few minutes to 48 hours. For rare and unusual circumstances these can take up to 72 hours.  The amount of time it takes to update DNS records is known as DNS propagation. A Deeper Explanation of What Is DNS Propagation? DNS propagation is a fundamental part of the DNS.  DNS is considered as the address book of the internet. When you send and receive emails, email service providers will query the DNS system, and will locate where the message should be routed.  Updating this is crucial to make sure that DNS records are not cached. An outdated DNS record will still be cached on some servers that may lead to your emails not reaching their intended destination or recipient. Updating the DNS may take some time to propagate, hence the term “DNS propagation. ” If the conditions are correct, it shouldn’t take extremely long.  Why Does DNS Propagation Happen? Until all servers refresh their cached data, some users might see the old records, while others see the new ones. This delay can cause inconsistencies in email routing and authentication. In some cases, DNS servers may update more quickly in certain regions, while others take longer due to caching policies and ISP infrastructure. Larger ISPs may have internal caching mechanisms that refresh at different intervals, further extending the propagation time... . --- ### How Email Warm Ups Transform Cold Outreaching > Content marketing and cold outreach may not be exciting, but ignoring them will only create bigger challenges down the road. - Published: 2025-02-11 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/how-email-warm-ups-transform-cold-outreaching/ - Categories: Blog - Tags: Marketing Content marketing and cold outreaching is a little like filing your taxes or going to the dentist. It may not be in the list of activities you wake up beaming with excitement for but if you ignore it, things will get worse. As appropriate as that comparison is, there are some notable differences. Taxes and dentist appointments have very few variables and an almost immediate feedback loop, unlike cold outreach and content marketing. Sending sales emails, on the other hand, also feels a lot like shouting into the void. Your prospects don’t know you yet, and a well-crafted email alone isn’t always enough to earn their trust. This is where email warmups come in. Here at Warmy, we understand that before we uncover and strike at the heart of email contents — which is engagement — we must first understand the ironclad armor which is a reputable email domain. Having an email warmup system can use valuable content to nurture leads hand-in-hand, but in reality a valuable content would not be effective if it will be sent in spam. Email warmup and authentication are one of the secrets in unlocking an effective cold outreach. Email deliverability, is therefore, the most critical strategy, especially for every outreaching pursuit or initiative. It is a skeleton key that unlocks the right combination of content and email marketing that can help move leads from "never heard of you" to "let’s book a call.

It makes your business, or professional profile presentable.  Besides its aesthetic potential, multiple email identities can also be an effective system to effectively communicate with different audiences. However, acquiring various main email accounts can be time consuming and may result in mismanagement of email communication.  This is why various businesses employ the use of email aliases.  Utilizing email aliases in platforms like Google Workspace and Outlook are instrumental in streamlining email marketing, improving organizational workflow, and centralization of email communication.  But it doesn’t mean that email aliases are without challenges. Improper configuration or excessive use of aliases has the potential to negatively impact your email deliverability and sender reputation.  In this guide, we’ll explain what an email alias is, how it works, how to properly configure it in Google Workspace, Gmail, and Outlook, and how to optimize your email aliases for better deliverability. What is an Email Alias? Email aliases is an alternative email address used for forwarding incoming emails to primary domain.  In conjunction with a separate email account, an alias does not have an independent mailbox.

Even a minor issue can harm your reputation and impact email success. - Published: 2025-02-11 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/how-to-use-spf-flattening-tools-to-optimize-your-email-deliverability/ - Categories: Blog - Tags: Email Deliverability Email authentication is a vital procedure for maintaining high email deliverability. Having the slightest chance of your email authentication derailing can and will affect your reputation. One of the most important email authentication methods there is, the Sender Policy Framework (SPF), an authentication method confirming every email sent using your domain has full authorization by mail servers. However, SPF records have a limitation: they can only perform 10 DNS lookups before exceeding the permitted limit, leading to potential failures in email authentication. This is where SPF flattening comes in. SPF flattening tools optimize SPF records by reducing the number of DNS lookups, ensuring better performance and compliance with SPF policies. This blog will explore how SPF flattening works, various tools available—including free SPF flattening tools—and best practices for implementation. https://youtu. be/5VP9wbtZ1c0 What is SPF Flattening? Understanding SPF and DNS Lookup Limits SPF records work by specifying a list of authorized mail servers that can send emails on behalf of your domain. These records contain mechanisms such as include, a, mx, ptr, ip4, and ip6, which require DNS lookups to retrieve the necessary data. The issue arises because SPF lookups are limited to 10 DNS queries, and exceeding this limit causes SPF validation to fail. How SPF Flattening Works SPF flattening is a technique that reduces the number of DNS lookups in your SPF record by replacing multiple “include” mechanisms with direct IP addresses. Instead of querying multiple external domains for authorization, SPF flattening consolidates the necessary IPs into a single, optimized... --- ### What Is SPF Flattening and How It Can Simplify Your SPF Records Without Losing Functionality > Lack of proper email authentication is one of the reasons why your emails are being sent to spam - Published: 2025-02-07 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/what-is-spf-flattening-and-how-it-can-simplify-your-spf-records-without-losing-functionality/ - Categories: Blog - Tags: Marketing Lack of proper email authentication is one of the reasons why your emails are being sent to spam. One of the most crucial authentication mechanisms for email is the Sender Policy Framework (SPF), a DNS record that prevents email spoofing — which is when scammers send messages that may appear as a legitimate email. It specifies which mail servers are allowed to send emails on behalf of a domain.  However, a long SPF record with excessive DNS lookups can lead to email delivery issues and even SPF PermErrors due to DNS lookup limits. To remedy this, the SPF authentication process must be implemented by email users. SPF flattening helps with the simplification of an SPF record by reducing the number of required DNS lookups while maintaining its functionality. Let us understand this further and uncover its importance to email deliverability and overall email performance. The Challenges of SPF: Understanding Common Issues SPF operates by defining a list of authorized mail servers in domain’s DNS records by using the TXT Record Format.  Usually, when a recipient receives an email, the email server checks the sender’s SPF record. This helps to confirm if the sender’s domain is authenticated and authorized.  SPF records, however, have a limitation. It is restricted to a limit of 10 DNS lookups. But what will happen if the limit is exceeded? If the server confirmed that a domain is using multiple email providers, the SPF record may exceed this limit. This phenomenon results in an SPF PermError.  If an email user experienced an SPF... --- ### Examples of Positive and Negative Feedback Loops in Email Deliverability > For email marketing strategists, understanding the recipient’s engagement level and their reactions to the email contents. - Published: 2025-02-07 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/examples-of-positive-and-negative-feedback-loops-in-email-deliverability/ - Categories: Blog - Tags: Email Deliverability For email marketing strategists, understanding the recipient’s engagement level and their reactions to the email contents can help them determine if the campaign is working, or needs further developments. This is an opportunity that would be difficult to determine without the presence of Feedback loops.  Feedback loops are widely regarded by email marketers to gauge if the recipients are interacting with the content, or sending them to spam. It is determined under two classifications: Positive Feedback Loops and Negative Feedback Loops.  For this blog, we will take a deeper understanding of positive and negative feedback loops, and some examples of how it can improve or impact email deliverability and sender reputation. Including some actionable strategy to leverage positive feedback loops, and avoid negative ones. Contribution of Feedback Loops in Email Deliverability Feedback Loop (FBLs) are systems used to collect user engagement data, and utilize it to influence email filtering decisions. Each mailbox provider — such as Gmail, Yahoo and Outlook — have a developed feedback loop that can cater to their users.  It is intended for mailbox providers to improve their spam filtering algorithms, and improve better user experience for email recipients.  Feedback loops are determined under two classifications:Positive feedback loops improve a sender’s reputation by reinforcing good email practices, such as high open rates and user engagement. Negative feedback loops degrade a sender’s reputation when recipients mark emails as spam or fail to engage with the content. Understanding and managing these feedback loops are one of the best practices to maintain high email deliverability and inbox... --- ### How to Use PTR Records to Improve Email Warmup and Deliverability > Implementing an effective email outreach program or initiating customer communications are vital for email deliverability. - Published: 2025-02-07 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/how-to-use-ptr-records-to-improve-email-warmup-and-deliverability/ - Categories: Blog - Tags: Marketing Implementing an effective email outreach program, sending marketing campaigns, or initiating customer communications are vital for email deliverability. Employing email warmup services, such as Warmy. io is a critical component to help establish a positive sender reputation and credible email account.  However, one of the overlooked aspects of ensuring a credible and reputable email is a properly configured PTR record (Pointer Record). Proper configuration of the PTR record, by an ISP or hosting provider that owns the IP address ensures that email servers recognize your IP address as a legitimate email. PTR records are therefore necessary to minimize the likelihood of emails being flagged as spam.  But what are the specifics that make PTR records essential in the pursuit of email deliverability? Would it be sufficient to have a fully configured PTR record? Let’s find out. Understanding the Acronym: What is a PTR Record? A PTR record is a type of DNS (Domain Name System) record that maps an IP address to a domain name. Without this, your emails may probably end up in spam or junk. It is considered as an anti-spam police and has significant contribution with the verification and legitimacy of an email server — alongside other email authentication processes, such as SPF, DMARC and DKIM. This process is known as reverse DNS lookup. Email providers and spam filters use PTR records or ,reverse DNS lookup, to verify that the IP address sending emails corresponds to its assigned and expected domain.  Some email providers (especially corporate mail servers and certain ISPs) may reject emails... --- ### How DNS Propagation Delays Affect Email Deliverability and What You Can Do About It > DNS is the backbone of all your internet activities.

Understanding why Yahoo emails bounce back - and knowing how to fix it - can make all the difference. Often, the issue isn’t about your content or even your recipients.

These addresses lead to “hard bounces” that immediately reject your email. ✅ Recipient's Mailbox Full.  Yahoo users with full inboxes can’t receive new messages. When an inbox is full, Yahoo returns your email, marking it as undeliverable. This situation usually leads to a “soft bounce,” which means it might be accepted later when space clears. ✅ Spam Filters.  Yahoo has very strict spam filters.

When emails fail to reach the inbox, potential opportunities are missed and the sender's reputation may take a hit. One of the primary factors that may affect deliverability is having bounces, which happens when an email fails to find its way into a recipient's inbox. Email bounces are an essential part of the email process in order to have a clean working list and make campaigns most effective. Generally, a bounce comes in two types: soft bounces and hard bounces.  Hard bounces, in particular, are a more serious issue for deliverability because they typically occur when an email address is invalid or permanently unreachable. Having too many hard-bounce emails on your list can damage your sender's reputation and cause your emails to land in spam folders. At Warmy, we provide the most required solution for this problem - Email verification. This tool is specifically designed to prevent these issues by verifying email addresses before they’re added to your list. By reducing the number of hard and soft bounces, Warmy's tool helps you maintain a high level of deliverability and ensures that your emails get where they’re supposed to go. https://www. youtube. com/watch? v=qMrAqLuN0eE What is an Email Bounce?

But the success of email marketing depends much on deliverability - that is, the proportion of emails that find their intended receivers. Recent research indicates that, usually owing to technological problems, as much as 20% of marketing emails are never sent. One such technological difficulty relates to MIME types. Essential parts of email communication are MIME (Multipurpose Internet Mail Extensions) kinds. They specify the structure of the content in an email, therefore guiding the receiving email client on appropriate interpretation and display of such material. For example, "image/jpeg" denotes the presence of an image; a MIME type of "text/HTML" indicates that the email include HTML content. MIME types improve user experience by guaranteeing emails show as intended when set up properly. On the other hand, poorly set MIME types might result in major deliverability problems, flag emails as spam or, worse, reject them completely. This paper will explore the common indicators of MIME type mistakes, how they could impair email deliverability, and doable solutions for these problems. https://www. youtube. com/watch? v=JEghLpYTuDw Understanding MIME Types Standard MIME, or Multipurpose Internet Mail Extensions, expands email message format to include attachments of audio, video, photos, and application programs as well as text in character sets other than ASCII.

Learning from Mistakes.  As you send more emails, you'll get feedback. Maybe some emails bounce back, or some people mark them as spam. By warming up your IP, you can learn from these issues and fix them. 4. If you send too many emails too fast, you might end up on a blacklist, which is like a naughty list for IP addresses.

What is email deliverability? Email deliverability is the ability to successfully send out emails from one client to another. It entails ensuring that a sender’s emails are successfully delivered to their intended recipient, and that it does not get flagged as spam or blocked by the email provider.  Factors like sender reputation, content quality, authentication protocols, and proper address formatting all have an effect on email deliverability. Sender reputation is probably the most important factor in determining if emails will be delivered or not. This is decided based on how often the sender’s domain has sent out valid emails in the past, and whether they triggered anti-spam regulations repeatedly.  Since ISPs want to protect their users from unwanted emails and spam, they mainly look at how trusted a sender’s domain is when evaluating deliverability success. Content quality also plays a key role in delivering successful emails.  Authentication protocols are necessary in order to prove legitimacy of senders, and these include SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based... --- ### Conquering the Inbox: Leveraging ESPs and ISPs for Maximum Reach > Discover how to effectively utilize ESPs and ISPs to enhance your email campaigns.

These computers have been exploited by unauthorized third-party entities, leading to activities such as the operation of open proxies, the propagation of worms and viruses equipped with spam distribution mechanisms, and the execution of various Trojan-horse exploits. https://www. youtube. com/watch? v=KLFpddhnxsM Reasons for inclusion in the Spamhaus XBL blacklist 1. Infected Systems One of the primary reasons for a system to be blacklisted is the presence of infections. Computers that have been compromised due to malware, viruses, or other malicious software can become tools for cybercriminals. These infected systems can be remotely controlled to send out vast amounts of spam emails. The unauthorized dissemination of spam not only disrupts the recipients but also tarnishes the reputation of the IP address from which the spam originates. As a result, these compromised systems are flagged and added to the Spamhaus XBL Blacklist to prevent further spamming activities. 2. Open Proxies Open proxies are another significant concern for email service providers. An open proxy refers to a system that has been configured, either intentionally or accidentally, to serve as an intermediary for the transmission of emails. These systems allow unauthorized entities to send emails, masking their original IP addresses. By doing so, spammers can hide behind these open proxies to send unsolicited emails without being directly traced. Due to the potential misuse of open proxies in spamming activities, they are often detected and blacklisted to curb... --- ### 14 Tips For Writing An Excellent Email Subject Line + Examples > Writing a great email subject line is key to getting your email opened.

CTOR is an email marketing metric that comes from click-to-open rate and measures the number of clicks on a link or links in your email compared to those unique opens. Or, in other words: percentage of people who clicked on a link from an email after opening it. CTOR is a better measure than CTR because it measures how engaged the recipient was with email content, not just that someone clicked. How to calculate CTOR? CTOR = (number of users who followed the links/number of open letters) * 100%To answer how to calculate CTOR, start by dividing the number of unique clicks by the number of unique opens for your email. Then, multiply that result by 100 to express it as a percentage.

Backlinks, also known as inbound links or incoming links, link from one website to another. In the context of search engine optimization (SEO), backlinks are considered an important factor in determining the ranking of a website in search engine results pages (SERPs). When a website links to another website, it is essentially vouching for the content on that site. Search engines like Google use this information to evaluate the quality and relevance of a website's content, and use it as a factor in determining its ranking in search results. What are the types of backlinks? There are several types of backlinks that can impact a website's search engine optimization (SEO) and online visibility.

To help ensure your company succeeds in the long run, here are the top ten customer acquisition mistakes that need to be avoided in 2024. https://www. youtube. com/watch? v=89cVd88MRmw The most common mistakes made in the lead generation process 1. One of the biggest mistakes is misunderstanding the target audience. Any business needs to start with the formation of a clear portrait of your potential client, studying his needs and tasks. The rule does not work here, the more the better, quantity rarely turns into quality. Calling 1,000 companies from a purchased base and getting 990 rejections is definitely worse than making 100 calls to targeted, selected prospects. 2. One offer for all. Such an offer is suitable only for very highly specialized companies that promote one single product. For those companies that have several types of products or lines of business, the proposals need to be tailored to each type of client. To create such offers, you need to understand the specifics of customers and their pain points. 3. Uncoordinated work of marketing and sales. The marketing department generates leads well, but they don't turn into leads. Why is this happening? There can be many reasons - marketers bring inappropriate leads, sales managers are not motivated to work with incoming contacts, there are no clear processes for working with a sales... --- ### Backlinks: Understanding the Importance of Link Building for SEO > Learn why link building is important for SEO, what types of links exist, and how you can build effective backlinks that will help your website rank higher. - Published: 2023-12-26 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/what-are-backlinks-and-why-are-they-needed/ - Categories: Blog - Tags: Other A successful SEO strategy starts with understanding the importance of link building.

Link building is a fundamental part of any SEO campaign, but many websites overlook it altogether or don’t understand how to successfully implement it into their overall strategy. But before you can begin your backlink-building efforts, it’s important to first understand what backlinks are and why they matter for SEO. In this post, we will go over everything from what backlinks are to best practices for link building in 2020 so that you can ensure your website succeeds in its search engine optimization efforts. https://www. youtube. com/watch? v=PYCV4yveV0E What are backlinks and why are they needed? Backlinks, also known as inbound links, are links from other websites that point to your website. They are an important factor in search engine optimization (SEO) because search engines like Google use them to determine the quality and relevance of a website. Backlinks are needed because they help to improve a website's visibility and authority.

Said another way, it's the software that uses a client-server architecture to move electronic mail messages from one computer to another. Controlling the intricate routing and delivery procedures that support our everyday email exchanges, an MTA acts as a kind of digital post office. The MTA responds to all kinds of messages - personal or business - with amazing accuracy, whether they are sincere or urgent.

However, the widespread use of email has also made it a prime target for cyber threats, such as phishing, spoofing, and unauthorized access. To counter these challenges and ensure the authenticity of email communication, three essential email authentication protocols come into play: SPF, DKIM, and DMARC. https://www. youtube. com/watch? v=eSVqOBA3z_4 1. Understanding SPF (Sender Policy Framework) SPF, short for Sender Policy Framework, is an email validation system designed to prevent email spoofing. Email spoofing occurs when a malicious actor impersonates a legitimate sender's email address to deceive recipients. SPF works by allowing domain owners to publish a list of authorized email servers, thereby enabling email receivers to verify the authenticity of incoming messages. To implement SPF, domain owners need to create a DNS (Domain Name System) record containing a list of IP addresses authorized to send emails on behalf of their domain. When an email is received, the recipient's email server can check the SPF record to ensure that the sender's IP address matches the list of approved servers. If the validation fails, the email may be marked as spam or rejected altogether. Take the first step towards securing your email delivery with Warmy's Free SPF Record Generator. Our user-friendly tool simplifies the creation of SPF records to protect your domain against spoofing and ensure your emails reach their intended destination. Don't let your messages get sidelined by spam filters.

Domain Warm-up refers to the process of gradually establishing a positive reputation for a new or inactive email domain before sending a large volume of emails. It involves gradually increasing the volume and frequency of email sends over a period of time to build trust with email service providers (ESPs) and ensure good deliverability. Why is domain warm-up necessary? Domain Warm-up is necessary for several reasons. First, it helps prevent emails from being marked as spam or ending up in the recipients' junk folders. When a new domain starts sending a high volume of emails without a warm-up, it may trigger spam filters, leading to poor deliverability.

What exactly is the difference between the two protocols, and which one should you use when setting up your company’s network?  In this blog post, we’ll explore the technical differences between IPv4 and IPv6 as well diving into their respective advantages. Whether you’re an IT specialist or simply want to know more about these topics, there will definitely be something here of interest. https://www. youtube. com/watch? v=u2eWuj5bc0o Technical differences between IPv4 and IPv6 ✅ Addressing Scheme The most significant difference between IPv4 and IPv6 is the addressing scheme. IPv4 uses a 32-bit addressing scheme that allows for a total of 4. 3 billion unique addresses. While this may seem like a lot, the rapid expansion of the internet has resulted in a shortage of IPv4 addresses, which has led to the use of Network Address Translation (NAT) and other techniques to conserve IPv4 addresses. IPv6, on the other hand, uses a 128-bit addressing scheme that allows for a virtually unlimited number of unique addresses, making it scalable enough to support the future growth of the internet. ✅ Header Format The IP header is the portion of the IP packet that contains information about the source and destination addresses, packet size, and other important information. The header format in IPv4 is fixed and uses a 20-byte header, while the header format in IPv6 is more flexible and uses a 40-byte header. The larger header... --- ### Unlocking the Secrets of Effective Cold Outreach: Tips and Techniques > Learn how to maximize your impact when it comes to cold outreach with this comprehensive guide full of tips and techniques. - Published: 2023-12-20 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/unlocking-the-secrets-of-effective-cold-outreach-tips-and-techniques/ - Categories: Blog - Tags: Marketing It can often feel intimidating to reach out to cold leads, but mastering the art of effective cold outreach can be a game-changer for individuals and businesses alike.  When done strategically, cold outreach is an incredibly powerful tool that offers limitless opportunities and potential for growth.

Establishing and upholding a positive domain reputation has become increasingly imperative for individuals and businesses alike. Such a reputation holds considerable sway over various facets of your online activities, encompassing email deliverability, search engine rankings, customer trust, and the overall credibility of your brand. The notion of email domain reputation pertains to the perceived reliability and trustworthiness assigned to a specific domain name or website by internet service providers (ISPs), search engines, and users. Multiple factors contribute to shaping this reputation, including the historical track record of the domain, its sending practices, the quality of its content, the level of engagement it generates, and its adherence to industry standards and regulations. The importance of email domain reputation is underscored by its impact on crucial aspects of your online operations. A favorable email domain reputation bolsters email deliverability by ensuring that your messages make their way into recipients' inboxes instead of languishing in the dark abyss of spam folders.  Furthermore, it influences the visibility of your website in search engine results pages (SERPs), as search algorithms take domain reputation into account when determining rankings.

Reverse DNS, or Reverse Domain Name System, is a process used to resolve IP addresses back to domain names. While the standard DNS translates domain names to IP addresses, allowing us to access websites using human-readable names, Reverse DNS does the opposite. It's particularly useful for network troubleshooting, security verification, and ensuring that a given IP address is genuinely associated with a specific domain, especially in email communication. The Role of SMTP in Email Communication Simple Mail Transfer Protocol (SMTP) is the backbone of email communication. It's a set of rules that govern the sending of emails from one server to another. When you send an email, it's the SMTP server that pushes that email to the recipient's mail server. Think of SMTP as the postman of the digital world, ensuring that your messages get to the right mailbox in a standardized manner. Introduction to SMTP Banners SMTP banners are the initial greeting messages that an SMTP server sends when another server or client connects to it.

An email thread works in much the same way. At its core, an email thread is a series of related emails, grouped together based on a common subject line. It’s like a storyline, where each email acts as a chapter or continuation from the last, providing an ongoing narrative of a conversation. Creating an email thread is pretty straightforward. It begins when someone sends an initial email. As recipients reply to that email, or as the original sender continues the conversation with follow-up messages, those subsequent emails get linked together, primarily due to the consistent subject line. In some email platforms, you might notice a 'Re:' prefix added to the subject, indicating it's a response. The beauty of email threads, especially when viewed in a threaded or 'conversation' view in email clients, is that they provide a clean, organized way to keep tabs on a discussion. Instead of sifting through a chaotic inbox searching for related messages scattered here and there, everything's neatly tucked together. It's like having a neatly-folded stack of letters rather than a jumbled mix. This not only helps in easily tracing the history and context of a conversation but also keeps your inbox tidier and more manageable. https://www. youtube. com/watch? v=1czDC9JjXto Advantages of email threading - Reduce Inbox Clutter.

A generic email address is a catch-all address. It represents a team or department rather than a specific person. Examples are "info@company. com" or "support@service. com. " This type of email is often used to receive general inquiries or customer service requests. Role-based email addresses are assigned to specific roles within a company, like "manager@company. com" or "hr@firm. com. " They focus on a particular job or function rather than a single person. Knowing the difference between these types helps businesses manage email communication better. https://www. youtube. com/watch? v=wRgLlqz_cGE What are Generic Email Addresses? A generic email address typically represents a broad category or function rather than an individual within an organization. It serves as a general point of contact, ensuring that messages reach the company without being directed to a specific person. Generic email addresses, such as "info@company. com" or "support@brand. com," offer a centralized point of contact, ensuring that inquiries or feedback are received and can be appropriately routed within the organization. Such addresses present a unified front, often giving the impression of a well-organized business structure. Reasons Businesses Opt for Generic Email Addresses ✅ Efficiency. By directing general inquiries to a single address, businesses can streamline their communication processes, ensuring that no message goes unnoticed. ✅ Flexibility. As these addresses aren't tied to individual employees, there's no need to update external contacts if there's a change in personnel. Common Examples of Generic Email Addresses:  contact@company. com  helpdesk@serviceprovider. com  sales@retailer. com  feedback@organization. org  info@company. com  hello@startup. net  inquiries@business. com  support@serviceprovider. com  help@platform. org  questions@organization. net  assistance@tool. com  general@enterprise. org Advantages and Disadvantages of... --- ### Email warm-up | All You Need to Know > Email warm up tool - is a fast, simple, and affordable way to improve email deliverability and increase your open rates. - Published: 2023-12-15 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/email-warm-up-all-you-need-to-know/ - Categories: Blog - Tags: Email Deliverability We've seen salespeople lament that their emails go to spam within weeks of launching a new email domain or adding a new email address to an existing domain. They claim to have only recently begun sending emails to their prospects and yet, their emails end up in their prospects' spam folders within weeks. But why do email clients label a new email address as spam just a few days after it is created?  When a recipient notices that a freshly generated email domain or email id is sending emails, it begins to examine the volume it generates. Because many email clients employ email volume to detect spam, if the number of emails sent is more significant, the email client is more likely to consider it with suspicion.  Suppose a salesperson or email marketer sends a large number of emails from their email address after creating a new email domain or id. In that case, the recipient will label the email address and the email domain as spam. To prevent this, send minimal emails from your domain or email address at first to establish a reputation for your email account.  When advertisers utilize automated email distribution tools to send emails, it's good to use email warm up tool to establish credibility for the email first so that subsequent communications don't end up in spam.  https://www. youtube. com/watch? v=BNzeJ-K_lhw What is email warm-up Email warm up is the process of gradually increasing the sending volume and reputation of a new email account or IP address to avoid being flagged as spam.

Improve your email deliverability - Published: 2023-12-13 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/how-to-warm-up-an-ip/ - Categories: Blog - Tags: Email Deliverability IP Warming, in the context of email marketing, is a gradual process of building a reputation for a new Internet Protocol (IP) address, or an IP that has not been used for some time. This process involves gradually increasing the volume of emails sent from the new IP address over a period of time. The purpose is to establish a positive sending reputation with Internet Service Providers (ISPs) and spam filters. https://www. youtube. com/watch? v=TPr6qOM3_YU Importance and purpose of IP warming The importance of IP Warming cannot be understated in email marketing. The primary reason is that ISPs monitor the volume of emails coming from an IP address to prevent spam. When a new IP address suddenly starts sending large volumes of email, ISPs can flag these emails as spam or even block the IP address altogether.  IP Warming helps in preventing this scenario. By gradually increasing the volume of emails, the sender is more likely to establish a good relationship with ISPs and email clients, ensuring that the emails reach the recipients' inboxes rather than their spam folders. This practice can significantly improve the deliverability and effectiveness of email marketing campaigns. Understanding the concept of "Cold" and "Warm" IP A "cold" IP is an IP address that hasn't been used to send emails for a significant period of time or a completely new IP address with no sending history. ISPs don't recognize these IPs and thus are more likely to be suspicious of large volumes of emails coming from them. On the other hand, a... --- ### The Difference Between Deliverability and Email Delivery Rate > Understand the distinction between deliverability and email delivery rate – two critical metrics that determine how effective your email outreach is. - Published: 2023-12-13 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/what-is-email-delivery-rate/ - Categories: Blog - Tags: Email Deliverability If you’re responsible for maintaining the performance of your organization’s email marketing program, it’s essential to know the difference between deliverability and email delivery rate.  Many people confuse them as one in the same; however, they have different meanings and effects on an advertising program.  Deliverability is a measure of how successfully emails are sent through networking or ISP servers to reach an inbox while delivery rate is an indicator showing how many emails actually reach the recipient's inboxes after being sent.  In this blog post, we'll explore both terms in detail and explain why understanding their difference can help you optimize your email campaigns! https://www. youtube. com/watch? v=unCymphLKfE What is email delivery rate? Email delivery rate refers to the percentage of emails that are successfully delivered to recipients' inboxes, out of the total number of emails sent. It is a key performance indicator (KPI) used in email marketing to measure the effectiveness of an email campaign and the ability of an email service provider (ESP) to deliver emails to the intended recipients. Email delivery rate is calculated by dividing the number of emails delivered to recipients' inboxes by the total number of emails sent, and then multiplying by 100 to express it as a percentage. It is typically monitored and analyzed along with other email marketing metrics such as open rate, click-through rate (CTR), and conversion rate to assess the overall performance of an email campaign. A high email delivery rate indicates that a significant portion of emails are reaching the intended recipients, which is important for successful... --- ### From Good to Great: Factors That Affect Domain Reputation > Explore the factors that can make or break your domain reputation.

The truth is, if you want to make sure that your messages are seen by those who need to see them, it's essential that you understand why this might be happening - and just what steps should take to stop it from occurring again!  In this blog post, we'll explore ten reasons why Gmail may be blocking your emails and how best to address each issue. Let's get started! https://www. youtube. com/watch? v=SzIxHbAa_C8&t=1s Reason #1. Spam content Gmail uses advanced algorithms to detect spam emails and prevent them from reaching the recipient's inbox. If your email contains spammy content, such as excessive use of capital letters, multiple exclamation marks, or suspicious links, Gmail may block it. To avoid this, ensure that your emails are well-written, have relevant content, and do not contain any suspicious links or attachments. Example: If you're a business owner sending out promotional emails, avoid using words like "Free," "Urgent," or "Limited Time Offer" in your subject line, as these can trigger Gmail's spam filters. Reason #2. High bounce rate A high bounce rate occurs when a large percentage of your emails are returned to the sender as undeliverable. This can happen if the recipient's email address is invalid or if your email... --- ### The benefits of SendGrid SPF Record and SendGrid DKIM Record > Learn about the importance of SendGrid's SPF record and DKIM record, and how they can help improve your email deliverability. - Published: 2023-12-12 - Modified: 2025-04-09 - URL: https://blog.warmy.io/blog/the-benefits-of-sendgrid-spf-record-and-sendgrid-dkim-record/ - Categories: Blog - Tags: Email Deliverability Welcome to the world of SPF and DKIM authentication!

In this blog post, we’re going to discuss what it means when we talk about a “SendGrid SPF or DKIM record,” its advantages and how to set them up on your domain correctly.  So put on your security cap and let's get started! https://www. youtube. com/watch? v=8w11KM8q6cw Why do I need to configure Sendgrid SPF, DKIM, DMARC? Configuring SPF, DKIM, and DMARC for SendGrid is important for a few reasons: 1. Email authentication These protocols help to authenticate your email messages, proving that they are genuinely sent from your domain, and not from a spammer pretending to be you.

Deliverability By configuring SPF, DKIM, and DMARC for SendGrid, you help to ensure that your messages are delivered to the intended recipients' inboxes.

An email alias is an alternate email address that forwards messages to another account.  It can be used as a substitute for a primary email address in order to keep personal and business accounts separate, or for more privacy when engaging in online activities such as shopping or social media.  An email alias also allows users to create multiple addresses for use with various websites, eliminating the need to give out their primary email address.  With an email alias, the user can keep track of which websites they gave their contact information to by noting which alias was used.  Additionally, if one of the services you've signed up for experiences a data breach, you can easily delete that single email alias without having to update all your other accounts with a new address.
