This page will test your email servers IP address against several blacklists.

Please Note

As this tests against quite a few blacklists it can take some time so please be patient, either results or ‘IP Not Listed’ will appear below the testing box!

An email blacklist, also known as a DNS-based Blackhole List is a real-time database that uses set criteria to determine if an email server (identified by it’s IP address) is sending email that could be considered spam. There are many blacklists, including Spamhaus, Barracuda Reputation Block List, and SpamCop to name a few, but they all have their own criteria for accepting inbound mail and all can have a negative affect on your delivery rate and in some cases stop delivery altogether.

Instructions

Either press the submit button to test the IP address detected or enter the IP address of the email server you wish to test if you know it.

If your results show that you are listed, then contact us to discuss your options…
