One address, a whole list or your sending domain. Choose the workflow that fits your next step.
Check an address before you add it to a campaign. See its status, risk score and the reason behind the result.
Turn a name and company domain into likely address patterns, then deep-check candidates before returning a match.
Review SPF, DKIM, DMARC and the other sending-domain checks that affect your readiness to send.
Import - Verify - Live Results ; Single, Bulk or APIs
Paste or upload your contacts, review and submit. Or submit from your product via our API Integrations.
We check every address live, real-time and identify valid, invalid, catch-all, disposable, role-accounts, unknown and spam-traps across every address.
View every result, filter by status and export the clean rows you need for your next send. Get your clean list and send with confidence.
InboxValid’s verification engine stays the source of truth. AI will help explain those results, spot patterns across a list and prioritize what to fix—without inventing a mailbox verdict.
Turn mailbox signals, provider responses and risk flags into a plain-language recommendation for each address.

We check the receiving mail server. We do not send a message to the address you verify.
See status, risk score and the reason together. Unknown stays unknown instead of becoming a guess.
Keep valid addresses, review catch-all and risky results, and separate invalid contacts before sending.
Your contacts are processed to return verification results, not to create marketing lists for other customers.
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.

A useful check explains uncertainty. Review the status, risk score and reason together. Verification cannot guarantee delivery or inbox placement.
| Result | What it means | Your next step |
|---|---|---|
| Valid | The checks indicate a usable address. | Include it in your reviewed list; delivery still depends on your sender setup and campaign. |
| Invalid | The address failed verification. | Remove it from your send list or correct it before checking again. |
| Catch-all | The domain accepts mail for addresses that may not have a real inbox. | Review separately; acceptance is not proof that a person will receive your email. |
| Risky or disposable | The address has signals that deserve extra attention. | Review the reason and decide whether it fits your campaign. |
| Unknown | The check could not reach a confident answer. | Keep it separate and check again later; do not treat it as valid. |
