Check if your domain is on an email blacklist.
This checks your sending domain — and any sending addresses your own SPF record declares — against the Spamhaus domain blocklist. We deliberately never judge your reputation by your website’s IP address, a different, unrelated signal. Paste up to 15 domains below to see live blacklist status alongside 4 more checks.
Questions
Email Blacklist Checker FAQ
Is this the same as checking my website’s IP reputation?+
No. Your website’s IP is usually a shared CDN address with no relationship to your mail sending reputation. This check looks at your domain and the addresses your SPF record actually declares for sending.
What does it mean if the blacklist query is refused?+
A refused query means the blocklist didn’t answer at all — usually a resolver-level block — so we genuinely can’t say listed or not.
What should I do if my domain is listed?+
Fix the underlying sending practice first, then request delisting from the blocklist operator directly. WarmHawk’s paid dashboard also monitors listings continuously.
