About
Your emails deserve to arrive
IsMyEmailBlacklisted was built because too many businesses discover they're blacklisted only after their emails stop arriving. We built the monitoring tool we wished existed — fast, thorough, and focused on actually fixing problems, not just reporting them.

Our Mission
Email deliverability is broken. The average business doesn't know their sending IP is on a blacklist until customers complain they never got the invoice, the welcome email, or the password reset. By then, the damage is done.
We set out to build a monitoring platform that catches these problems before they impact your business. Not a tool that runs a check once and moves on — a system that watches your domains 24/7 and tells you the moment something goes wrong, with the exact steps to fix it.
Every blacklist in our system is DNS-verified alive. Every playbook has been tested against the actual delisting process. We focus on accuracy over inflated numbers. If we say you have a problem, you have a problem — and we tell you exactly how to solve it.
What We Believe
Transparency First
No hidden checks, no fake results. Every blacklist query is a real DNS lookup, every score is calculated from actual data. We show you exactly what we find.
Speed Matters
When you're blacklisted, every minute counts. We run 60 concurrent DNS lookups and deliver your full report in under 10 seconds. Alerts fire instantly.
Fix It, Don't Just Find It
Knowing you're blacklisted isn't enough. Every issue includes a step-by-step remediation playbook with the exact actions needed to resolve it.
