Frequently Asked Questions
What does the validator check?▾
RFC 5322 syntax compliance, domain DNS resolution, MX record existence, and common typo detection (e.g. gmial.com → gmail.com).
Can it verify if an email actually exists?▾
The tool verifies syntax and domain/MX records. Full mailbox verification would require sending a test email, which is not done to protect privacy.
Can I validate multiple emails at once?▾
Yes. Enter multiple emails separated by line breaks or commas. Each email is validated independently.
