About Blacklist Lookup

Blacklist Lookup checks a domain or IP address against the main DNS blacklists used by email providers to reject spam.

How to use the Blacklist Lookup

1. Enter your domain or mail server IP.
2. Click Submit.
3. If you are listed, fix the cause and follow the blacklist's removal process.

Why it matters

Being blacklisted sends your emails to spam or stops them arriving at all, which hurts every business that relies on email.
