About the SPAM Blacklist Checker Tool

The SPAM Blacklist tool will check your specified domain or IP address against multiple internet blacklists that record SPAM sources or hazardous content. This is a useful tool for anyone who would like to know their server's reputation and to help troubleshoot connection issues e.g. if e-mail is consistently bounced back or marked as SPAM for no discernable reason.

If your server IP address is blacklisted, then enquire with your webmaster or host for them to diagnose the cause. To help find the culprit, check your domain or IP address against our Reverse IP Address Lookup tool to find other websites and domains using the same IP address.
