Built to help you make a safer send decision

InboxValid is a verification and deliverability tool. It improves your list and shows you what needs attention; it does not promise that every message will land.

No email is sent

We check the receiving mail server. We do not send a message to the address you verify.

Every result has context

See status, risk score and the reason together. Unknown stays unknown instead of becoming a guess.

You decide what stays

Keep valid addresses, review catch-all and risky results, and separate invalid contacts before sending.

Your list has a clear purpose

Your contacts are processed to return verification results, not to create marketing lists for other customers.

Inside every verificationDeep checks behind every result

We look beyond the format of an address. Domain records, MX routing, provider behavior and receiving-server responses all contribute context to the status and risk signals you see.
