The honest email verifier.
Paste up to 20 addresses and get a verdict on each. Unlike most free checkers, this one has three answers instead of two — because roughly 13.5% of addresses genuinely cannot be verified by anyone, and pretending otherwise is how you delete real customers. No signup. Nothing stored.
| Address | Verdict | Why |
|---|
Valid the mailbox accepted our probe · Unverifiable a catch-all or non-committal server — nobody can be certain, use engagement history · Dead proven not to exist — safe to remove
