Free Email Verifier
Our free email verifier performs syntax validation, domain DNS checks, MX record lookup, and disposable domain detection so you can confirm whether an address is likely deliverable before you send. Email marketers use it to prune lists before campaigns; developers embed similar checks in sign-up flows; small businesses use it to validate customer contact details. Unlike a simple regex test, this tool inspects real DNS configuration so you catch domains that cannot receive mail. Results include a deliverability score and a clear pass/fail breakdown for each check. Use it on the home page for single addresses or combine with our bulk tools for larger lists. No credit card is required for basic verification.
How to Use This Tool
- Enter an email address in the field above.
- Click Verify Now to run syntax, DNS, and disposable checks.
- Review the score and per-check badges in the results panel.
- Remove or fix addresses that fail MX or disposable checks.
- Export or verify remaining emails with our bulk CSV tool if needed.
What This Result Means
Green or positive indicators mean the check passed. Warnings highlight addresses or settings that may cause bounces or spam folder placement. Red or failed checks should be fixed or removed before sending email. Use the breakdown to decide whether to keep, quarantine, or delete each address.
