Our email validation achieves 99.9% accuracy through a multi-step verification process that includes syntax checking, domain validation, MX record verification, and mailbox existence testing. We continuously update our algorithms to maintain high accuracy rates.

We identify invalid syntax, non-existent domains, inactive mailboxes, role-based emails (like info@, admin@), disposable email addresses, spam traps, and high-risk addresses that could harm your sender reputation.
