What are domain and IP blacklists?

Domain and IP blacklists are databases used by email providers to identify senders that may be sending spam or harmful emails.

When you send an email, the receiving server checks these lists. If your domain or IP is listed, your email may be blocked, rejected, or sent to spam.

These lists are maintained by organisations like Spamhaus and UCEPROTECT.

Why your domain or IP may be listed

A listing does not always mean you did something wrong. It can happen if:

• The IP was previously used by another sender

• The domain had past reputation issues

• You are using shared infrastructure

• There was a security issue

Why this matters

Blacklist listings can:

• Block your emails

• Send emails to spam

• Reduce your sender reputation

Check blacklist status in TrulyInbox

• Go to your dashboard

• Click on the blacklist count. (If you don’t see the blacklisting column, enable the “Domain Blacklisted” and “IP Blacklisted” columns to view it)

  

• View all listings
