Email Validator
Goes one step further than a regex check — verifies the domain actually has mail exchange (MX) records, catching typos in the domain part that syntax alone misses.
FreeNo sign-upLive data
Checks syntax locally, then verifies the domain has mail exchange (MX) records via a live DNS lookup.
How it works
- 1Enter an email address
- 2Syntax is checked instantly
- 3The domain's MX records are checked via live DNS
Who this is for
- Checking a single email address before sending
- Debugging a bounced email
- Verifying a domain is configured to receive mail
Frequently asked questions
- Does this confirm the mailbox exists?
- No — it confirms the domain can receive mail, not that a specific mailbox is active. Full verification requires an SMTP-level check, which this tool doesn't perform.
