Spam-trap detection
Avoid the addresses that get you blocklisted.
What it does
Why it matters
Hitting spam traps is one of the fastest ways to land on a blocklist. We flag the riskiest addresses so you can remove them before they damage your sender reputation.
Spam traps are invisible to you but very visible to blocklist operators, and a single hit can filter all your mail. We flag the high-risk patterns and long-dormant addresses most likely to be traps so you can drop them before they cost you.

Frequently asked
Can you guarantee no spam traps?
No tool can see every trap directly, but flagging the riskiest and long-inactive addresses dramatically lowers the odds of hitting one.
What raises trap risk?
Purchased lists, scraped data and addresses that have been inactive for a long time are the usual sources of recycled and pristine traps.
What should I do with flagged addresses?
Suppress them — the downside of removing a few real contacts is far smaller than a blocklist entry.
