Verification runs through multiple steps automatically. First, we check the email syntax for formatting errors. Then we look up the domain's MX records to confirm it can receive mail. Finally, we connect to the mail server to verify the mailbox exists β all in under 2 seconds.
Our email checker achieves 99.9% accuracy by combining syntax validation, DNS lookups, MX record checks, and direct SMTP verification. This multi-layer approach catches issues that basic validators miss.
