Question 1

What is an email blacklist?

Accepted Answer

An email blacklist (DNSBL) is a database of IP addresses or domains known for sending spam. If your IP or domain is listed, emails you send may be rejected or filtered to spam.

Question 2

How do I get removed from a blacklist?

Accepted Answer

Each blacklist has its own removal process. Some auto-expire (like SpamCop), others require a manual request (like Barracuda). Check the specific blacklist's removal page for instructions.

Question 3

Why was my IP blacklisted?

Accepted Answer

Common reasons include sending spam, having an open mail relay, compromised server, sending to purchased lists, or high bounce rates. Fix the root cause before requesting delisting.

Question 4

How often should I check blacklists?

Accepted Answer

Check weekly if you send regular email campaigns. Monitor after any unusual sending activity, list purchases, or server changes.
