Of course, you don't want this to happen, right?

Here is what you need to know about email domain blacklisting.

An email domain blacklist is a state where your email domain is listed as a blacklist due to suspicious usage. This can be detected by the server or by the email recipients. If you want to know more about spam emails, read the article about spam filters here

In general, an email domain can be blacklisted because you use a shared IP. Because your domain is used by many people, we don't know what others who share your IP are doing. They might be sending scam emails or spam emails, which can certainly affect email deliverability performance. This can also impact email delivery.

We recommend that to maintain the reputation of your email domain, you use a dedicated IP. This is because a dedicated IP uses a private address that only you have. Thus, you can more easily monitor domain activity. Unlike shared IPs, you cannot monitor how domain activity has been.

Another factor is that your email domain is reported as spam by your subscribers. This could be because the emails are deemed irrelevant, or you may have added the recipient's email without their consent or prior notification.

To find out if a domain is blacklisted, you can check it through sites like https://mxtoolbox.com/ and enter the domain you want to check the records for. After entering the domain, several email servers will check whether your domain has a good record or is detected as a blacklist.

A list of results from several email servers will appear. If a ✔ sign appears, the domain is categorized as safe; if a ✘ sign appears, your domain is detected as a blacklist. After scanning and knowing which email servers categorize your domain as a blacklist, the next step is to request that your domain be removed from the blacklist on that email server.

Generally, on those email servers, you can request blacklist removal so that email deliverability on the domain can recover. After you request blacklist removal and your request is approved, the next step is to restore your domain's reputation. Email deliverability will not immediately recover when the blacklist is lifted from your domain. It will recover gradually. You can try warming up the domain.
