About Email Validator

Frequently Asked Questions

Does this validator check if the email address actually exists?

The tool validates email format and checks that the domain has valid MX records (indicating it can receive email), but it cannot confirm whether a specific mailbox exists without attempting to send a message.

What email format rules are checked?

The validator checks for a valid local part (before the @), a valid domain (after the @), correct use of dots and special characters, and that the domain has a valid TLD — based on RFC 5322 standards.

Can I validate a list of email addresses at once?

Yes — paste multiple email addresses (one per line) into the bulk input field to validate an entire list at once, with results showing which are valid and which have issues.
