Which Checks Does Email Validator Perform?

Our Email Validator uses a multi-layer email validation process, with every single email going through all of these validation and verification steps:

  • Syntax verification (IETF/RFC standard conformance)
  • DNS validation, including MX record lookup
  • Disposable email address detection
  • Misspelled domain detection to prevent Typosquatting
  • SMTP connection and availability checking
  • Temporary unavailability detection
  • Mailbox existence checking
  • Catch-All testing
  • Greylisting detection

During the entire email validation process, we never send any email to the recipient address.
