Is your address on an email blocklist?

Enter your mail server's IP address, your domain name, or the IP address your broadband provider gave you, and we will check it against the main blocklists that receiving servers use. Free, no sign-up, and we do not ask for your email address.

Not sure of your IP address? Click "Use my current address" and we will check the address you are visiting from.

Checking 13 lists...

This checker is for people checking their own addresses. It is limited to 10 checks an hour per visitor. Please do not build tools around it.
