What Does This Email Validator Check?

Our email validator performs multiple layers of validation to assess the quality and deliverability of an email address:

  • Syntax Check — Verifies the email conforms to RFC 5321 format ([email protected]).
  • MX Record Lookup — Checks whether the domain has mail exchange (MX) records, meaning it can receive email.
  • Disposable Email Detection — Cross-references the domain against 2000+ known disposable/throwaway email providers.
  • Free Provider Detection — Identifies free email services like Gmail, Yahoo, Outlook, Hotmail, and more.
  • Role-Based Detection — Flags role addresses (admin@, info@, noreply@) which often have low engagement.
  • TLD Validation — Confirms the top-level domain is valid and not a made-up extension.

Frequently Asked Questions

The MX record check confirms the domain is set up to receive email, but it does not perform an SMTP mailbox-level check (which requires connecting to the mail server and would be blocked by most providers). The score indicates deliverability likelihood, not a guarantee the mailbox exists.

Invalid or disposable emails in your mailing list increase bounce rates, damage your sender reputation, and can get your domain blacklisted by email service providers. Cleaning your list regularly improves deliverability and campaign performance.
