Fast, accurate verification for business email — valid, invalid, catch-all, or unknown — through one simple API. Protect your sender reputation and stop wasting sends on dead addresses.
We check mailboxes at the source, not just syntax — so a "valid" really means deliverable.
Accept-all domains and security gateways (Proofpoint, Mimecast, M365) are reported honestly as risky, never faked as valid.
One POST request, a clear JSON verdict with provider and sub-status detail. Drop-in compatible with a NeverBounce-shaped route.
No subscriptions. Buy credits that never expire, at around 30% below the usual services.
Every result tells you the mail provider — Google Workspace, Microsoft 365, self-hosted, or a gateway.
Addresses are hashed in our caches and scrubbed from logs. Your list stays yours.
