Email Validator
Check whether an email address has a valid-looking format before you send.
✓ Everything runs locally in your browser. Nothing you enter is uploaded or sent anywhere.
How to use this email validator
Type an address and press Validate. The checker catches the usual syntax problems — a missing or doubled @, spaces, a missing or malformed domain, empty labels, and bad characters — and reports "Valid email format" only when everything looks right. It never contacts a mail server, so it can't prove deliverability.
How to use Email Validator
- Add your input — a file, text, or values depending on the tool.
- Adjust the options to get the result you want.
- Download or copy the result. Nothing is uploaded or stored.
