No need to flee, it’s totally free


    Cold mailing is one of the best ways to reach potential customers in today’s digital world, and having an optimized domain for it can make a huge difference. If you’ve ever sent out an email to a prospect or client without proper branding, you know the negative effects this could have on the overall impression of your business. 

    With a trusted domain name, not only will you be able to ensure that emails are delivered reliably and efficiently – but also create trust with recipients so they’re more likely to respond positively. 

    In this blog post, we’ll discuss how establishing a unique domain for cold mailing is crucial to success in marketing campaigns and show why it should never be overlooked when building a long-term strategy.

    What is cold outreach?

    Cold outreach refers to the practice of reaching out to potential customers or clients who have had no previous interaction with a business or individual. The outreach is typically unsolicited and may involve email, phone calls, direct mail, social media, or other means of communication.

    The purpose of cold outreach is to establish contact with potential customers, introduce them to a product or service, and ultimately, generate new business. It can be an effective way for startups or small businesses to grow their customer base, but it can also be challenging to get a response from people who are not expecting to hear from you.

    Cold outreach requires careful planning and execution to be successful. The message should be tailored to the recipient and personalized as much as possible to increase the chances of a response. The outreach should also be timely and respectful of the recipient’s time and preferences.

    Importance of a domain for cold outreach

    When creating your cold email campaign, you should pay maximum attention to your email domain. 

    As a first step, we strongly recommend that you create a new domain and not start your mailing list from the main domain. This will help you avoid sudden blocking of your primary domain and associated emails. 

    And in this article, we will provide some tips for creating and preparing your emails for cold mailing. 

    You can’t just create a new IP address and start sending thousands of emails from a mailbox without a corporate domain. More precisely, you can, of course, but you will be banned very quickly. 

    If you want a high deliverability rate, you need the email service that receives the email to consider you trustworthy. If so, they will pass your letter on. Otherwise, your email will end up in the Spam folder. Gaining the trust of an email provider usually takes time, but you can speed up the process. 

    Microsoft Outlook vs Google

    Whenever possible, it’s best to choose Outlook/Microsoft as your email provider, as data shows that they have the best overall deliverability. Although it’s worth noting that if you open a brand new account with them, they will initially place you on a lower quality IP address, which in turn will result in lower deliverability rates. Google is a great second choice, and they also have the added benefit of better support than Microsoft Outlook. So it’s worth keeping in mind if you’re not a techie and you might need help every step of the way. 


    Choose .com, .org or .io (in that order), not .co, which is usually quickly labeled as spam. There are other domain options as well, so a good tip is that the more expensive the domain, the less likely it is to be saturated with spam accounts. 


    This is perhaps the most important item when setting up an email account. These are two types of email authentication that basically verify that an email was sent by an authorized mail server to prevent spam and fraud.

    Warm up email

    Using the email warm-up service is a great idea if you don’t want to get labeled spam quickly. Email Warm-up services allow you to automatically interact with hundreds of mailboxes in a very natural way, so by the time you’re ready to send emails to your potential customers, you’ll have earned the trust of a range of email providers. 

    Warm up email usually takes at least a month. During this period, you may encounter the fact that the letters will not be delivered and will be given the appropriate status. This means that now the provider is checking your IP and, perhaps, the problem will be solved tomorrow. ISP blocking is a more serious problem. This means that your emails are not opening well, or you have overdone the amount sent per day. Luckily, you were going to write to other people anyway, and you can afford to take your time next time. And don’t forget to regularly check if your IP is blacklisted. 

    P.S. You need to start small, Gmail, for example, recommends sending no more than 10 letters for the first time. If you warm up email for marketing mailing, then start with the most active users and those who have recently registered, gradually pulling up and inactive ones. 

    Are paid email accounts better than free ones for cold mailing?

    Paid email accounts are generally better than free ones for cold mailing. Here are a few reasons why:


    Paid email accounts typically have better deliverability rates than free accounts. This is because they often have better spam filters and are less likely to be flagged as spam by email providers.


    Paid email accounts often offer more customization options, such as the ability to add your own domain or use your own branding in the email. This can make your cold emails look more professional and increase the chances of a response.

    Customer Support

    Paid email accounts typically offer better customer support than free accounts. This can be particularly important if you run into any issues with your email campaigns and need assistance.


    Paid email accounts often offer better security features, such as two-factor authentication or encryption. This can help protect your data and ensure that your email campaigns are secure.

    Overall, while free email accounts may be tempting, they often come with limitations and drawbacks that can hinder the success of your cold email campaigns. Paid email accounts are a worthwhile investment if you’re serious about cold emailing and want to maximize your chances of success.
