Every email passes through 6 validation layers before we return a result.

Syntax & Format

RFC-compliant syntax checking catches malformed addresses before they reach your list.

MX Record Lookup

Verify the domain has valid mail exchange records so the email can actually receive mail.

✦ AI

SMTP Verification

Connect to the mail server and confirm the mailbox exists without sending a message.

Disposable Detection

Detect and block temporary email services from 3,000+ known disposable providers.
