How does the email validation work?

The tool uses a comprehensive regex pattern that follows RFC 5322 standards to validate email format. It checks the local part, @ symbol, and domain structure.

The MX hint provides information about the email domain, such as whether it belongs to a well-known provider (Gmail, Outlook, etc.). Note: actual MX record lookup requires server-side processing.

Can I validate multiple emails at once?

Yes. Switch to Bulk Mode, paste multiple email addresses (one per line), and the tool will validate all of them and show valid/invalid counts.

Is my data sent to a server?

No. All validation happens locally in your browser using regex pattern matching.
