Free email checker. Clearer answers.

Check email syntax, mail routing and disposable-domain signals in one place. Clear results, useful next steps, and no sign-up.

What this tool checks

Enter an email address to check its format locally, then inspect the public DNS records of its domain. The address before the @ stays in your browser.

Email syntax

Checks common address formatting, length, misplaced dots and invalid characters. Internationalized domains are normalized; quoted and international local parts are marked unsupported rather than rejected.

Domain mail routing

Looks for MX records, explicit null MX and A/AAAA fallback. Finding a mail route does not confirm that an individual mailbox exists.

Disposable and role signals

Checks a dated community blocklist and labels shared addresses such as sales@. A role address is informational, not automatically invalid.

Frequently asked questions

Can you check if an email address exists?

These checks establish syntax and domain-level evidence. They do not connect to a mailbox or establish that a particular person can receive a message. Mailbox existence stays unknown.

Does the checker send an email?

No. It does not send a message or attempt an SMTP login. Only the domain is submitted for public DNS and blocklist checks.

Is an unlisted address safe?

Not necessarily. Absence from a disposable-domain list is only absence from that particular snapshot, not proof of trustworthiness or deliverability.
