Check an IP address for Blacklisting

Are you on an Email Blacklist?

Enter your website's IP address in the box below and click on "lookup" to use our email blacklist tool to check. If your address is found on a blacklist, see our article "How to get off an Email Blacklist" for more information.

(NOTE: this must be the address that your email is sent from. If you are unsure of what address to enter, contact your server administrator.)
