One email. Let’s check it.

Catch typos and provider flags before they become your problem. Preview checks don’t confirm a live mailbox.

Fair questions. Straight answers.

The fine print.
In normal-sized print.

Is this email checker free?

Yes. Check single addresses for free. For lists and API access, create an account with 100 free credits.

Does it send an email to the address?

No. Checks use DNS and mail server lookups without sending any message.
