Problematic contacts we found
From the team behind SpamKill (opens in a new tab) — spotting spam since 2018 · 100M+ contacts analyzed · Works with your platform:
The warning email isn't the problem. Your list is.
Dead & fake addresses
Lists decay roughly 25% a year. Every dead address is a bounce waiting to happen.
Bots using real people's emails
Bots fill your forms with other people's real addresses. They pass verification — then the real owner hits "report spam."
You pay for it twice
Bad contacts drag your sender reputation down and inflate your ESP bill every single month.
List rot happens to every list. Let's fix it — calmly.
A warning from your email platform is scary; email is your revenue channel. The good news: this is fixable, usually before your next send.
Since 2018, we've blocked bad signups at the door with SpamKill. Spam Clean is the other half of the job — removing the bad contacts already inside your list. Same team, shared detection methods.

"We got a bounce warning the week before our biggest send of the year. The free analysis showed us how much of our list was bad and gave us a sample we could check ourselves — that was enough to trust it. We paid for the deep clean, and the campaign shipped on schedule. No panic, no guesswork."

Why "verified" lists still get spam complaints.
Standard verifiers pass this contact because the address works. But Sarah never signed up — and when your email lands, she hits "report spam." Spam Clean catches these with name-to-email matching.
