What is a RATS-Spam Blacklist?

The RATS-Spam Blacklist is a blacklist that focuses on IP Addresses that have a history of abuse.

An example of abuse is spam resulting from an open-relay, virus traffic, or unsolicited bulk email.

When an unknown email first makes contact with a mail server, determining the authenticity and validity of the sender is difficult to assess due to the amount of unknown information a mail server has available to them with 1 piece of mail.

Blacklists exist for the benefit of the internet in general, as they act as a “No Entry” list based upon what negative behavior other mail servers have reported.

The primary activities that would land a domain onto a blacklist are high bounce rates, a large amount of emails being marked as spam, and low engagement with your emails
