    Step-by-step guide to performing an audit

    Ready to roll up your sleeves and dive into your email deliverability audit? Great! With Warmy’s free email deliverability test, it’s like having a GPS for your email journey. Let’s break it down into manageable steps, so you can steer clear of the spam folder and cruise straight into the inbox.

    1. Run free email deliverability test

    Launching a free email deliverability test using Warmy is a straightforward process that can provide valuable insights into where your emails are landing – inbox, spam, or otherwise. Here’s how you can get started:

    1. Copy Email Addresses

    Launching a free email deliverability test using Warmy is a straightforward process that can provide valuable insights into where your emails are landing – inbox, spam, or otherwise. Here’s how you can get started:

    2. Compose and Send Your Email

    Next, paste these email addresses into the ‘To:’ section of your email client. Type in any message you’d like to test – this could be a typical outreach email or newsletter. Once you’re ready, hit the ‘Send’ button.

    We send to:

    • Gmail
    • G Suite
    • Outlook
    • MS 365
    • Yahoo
    • iCloud
    • Zoho
    • Zoho PRO
    • SMTP

    Here you will be able to see your results of the last completed deliverability test:

    With a click of a button, we send on your behalf a personalized message to 43 different mailboxes that are not part of the warm-up network.

    In the test results, you will see the percentage of emails that ended up in the inbox and the percentage that ended up in spam, as well as those that were unreceived. Additionally, the results will include rates for all the most important email providers.

    2. Check email delivery score

    It’s like checking your email’s credit score. This score tells you how likely your emails are to land in the inbox. The higher the score, the more of your emails will be delivered to inbox.

    3. Use an email deliverability test to check for blacklisting, including both IP and domain blacklists.

    Check if your IP or domain is on any blacklists. Being blacklisted is like having a “Do Not Enter” sign for inboxes.

    You can find out if the IP from which you send emails is on blacklists.

    IP blacklist

    blacklist IP

    If you use shared servers, such as Gmail or Outlook, do not be frightened if you see yourself on any blacklists. These servers may be used by hundreds of other users and some of them may have ruined the reputation of this server. In this case, you should not do anything, usually, it does not affect the deliverability much.

    Domain Blacklists

    Also, you can observe whether your domain is on any of the blacklists.

    blacklist IP

    Do not panic if you see any of the marked blacklists, maybe you just use a shared server (Gmail or Outlook for example), or your domain is very young. In this case, you may be Listed for a while.

    In Warmy’s blog, you will find information on how to remove your IP from almost all known blacklists.

    4. Set up SPF

    Setting up Sender Policy Framework (SPF) is a crucial step in enhancing your email deliverability. SPF is an email authentication method that specifies which mail servers are permitted to send emails on behalf of your domain. Essentially, it’s like giving a list of approved senders to email providers, helping them to identify which emails are legitimately coming from you.

    Using the Warmy test, you will immediately see if there are any problems with the SPF settings.


    Introducing Warmy SPF Generator

    Now, you can also use our new SPF Generator tool at Warmy SPF Generator for a hassle-free generation of SPF record in four simple steps:

    • Enter your domain.
    • Choose your Email Service Provider (ESP).
    • Provide your email address.
    • Generate your SPF record.

    5. Set up DKIM

    DomainKeys Identified Mail (DKIM) is a technology used for email validation, allowing your domain to apply digital signatures to outgoing messages. This signature acts as a unique marker, enabling email providers to confirm that the message originated from a source authorized by your domain. DKIM plays a crucial role in preventing phishing and spoofing by verifying the legitimacy of your emails. This not only protects your brand’s reputation but also ensures the security of your recipients against harmful activities.

    A DKIM signature is a TXT record that is added to the site’s DNS zone settings. The entry itself looks like this:

    us._domainkey TXT v=DKIM1; k=rsa; p=XXXXXXXXXXXXXXXXXXXXX,

    where v — DKIM version, always takes the value v=DKIM1;

    k — key type, always k=rsa;

    p — unique code that can be generated in the mailing service.

    The Warmy test will indicate whether your DKIM entry is correctly set up and functioning as intended.


    6. Set up DMARC

    DMARC (domain-based message authentication reporting and conformance) is an email authentication protocol that helps protect users from spam and phishing emails. It works by telling email servers what to do with emails that fail authentication checks.

    7. Warm-up your email

    Just like you wouldn’t run a marathon without warming up, don’t blast a bunch of emails without warming up your account first.

    Email warm-up is a technique used to gradually increase the volume of emails sent from a new or underused email account. This practice helps build a positive sending reputation with email service providers, ensuring your emails are more likely to be delivered to your recipients’ inboxes rather than being marked as spam.

    Warming up emails automatically with Warmy.io is an efficient and effective way to prepare your email account for successful campaigns.

    8. Evaluating the excellence of your email templates

    Your email templates wield significant influence in your email marketing strategy. They can either charm your subscribers or doom your emails to obscurity.

    These templates are the face of your brand in your subscribers’ inboxes, and they can either leave a positive impression or consign your emails to the spam folder.

    It starts with the crucial first impression – a well-designed template exudes professionalism and captures attention, while a cluttered one can lead to instant deletion. Furthermore, your templates impact deliverability; poorly designed emails with spammy content can trigger spam filters, ensuring your message remains unseen.

    Legal compliance is not to be overlooked. Failing to include necessary elements like unsubscribe links or physical mailing addresses can lead to legal trouble.

    To ensure your emails are a “visual delight” rather than a “cluttered mess,” adhere to best practices. Invest in clean, responsive templates, use visuals judiciously to enhance your message, craft concise and relevant content, segment your email list for targeted communication, leverage A/B testing for optimization, and regularly update your templates to stay fresh and aligned with your evolving brand identity.

    9. Leveraging a separate domain for cold email outreach

    Expanding your business often means more outreach efforts, including cold emailing. However, this expansion comes with a risk: damaging your primary domain’s reputation. This raises a crucial question:

    Why is it important?

    Managing a clean outreach process can be challenging, especially when multiple people are involved. With numerous emails to send and your main domain handling transactional emails, it’s easy to see why you might want to consider a second domain.

    Just make sure it doesn’t look scammy

    While using a different domain is a smart move, it’s essential to maintain credibility. Ensure that your secondary domain doesn’t raise suspicions or appear untrustworthy. It’s a bit like having a second phone line for business – practical, as long as it doesn’t sound shady.

    Using a separate domain for cold emailing can help protect your primary domain’s reputation.

    10. Monitoring your email reputation

    Having addressed technical aspects, maintained a stellar reputation, and ensured the successful delivery of your emails through Warmy.io, what’s the next step? Embrace email reputation management and continue monitoring the health of your email campaigns with Warmy.io.

    One essential step is performing regular email deliverability tests. This will help you stay on top of your email deliverability situation and identify problems in a timely manner.
