RATS Spam Blacklist: What Is It and How To Remove Yourself From It

What Is The 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.  

How Do I Find Out If I Am On The RATS Spam Blacklist?

RATS-Spam Blacklists allows users to check their IP Address on their site for free as many times as they’d like to.  It’s a very simple process and does not require a username or password.  There are a lot of reasons your IP Address may have triggered RATS-Spam’s automatic ‘RAT’ detection traps:

  • Sending unsolicited spam

  • Sending viruses in the forms of links or attachments on emails 

  • Sending large amounts of bulk mail

The easiest way for you to determine if you are on a blacklist is to simply sync an inbox under the domain in question to our platform. Every inbox synced to Warmup Inbox gets run by the 24 most common IPv4 blacklists to determine if your inbox and associated domain has been listed on one.

How Can I Remove Myself From The RATS Spam Blacklist?

The email administrator must be the one who requests removal from the RATS-Spam Blacklist.  RATS-Spam offers an option to check your IP Address for free on their website.  If you think your IP Address was added to the RATS-Spam Blacklist by mistake, the process is simple… You just need to enter your IP Address, find it on the long list, and request removal.  RATS-Spam asks its users to please not abuse this privilege.   

How Do I Reduce My Risk Of Getting Onto The RATS Spam Blacklist?

  • Verify all email addresses before attempting outreach
