Verify email (SMTP)

Runs the same deliverability verification used for contacts (SMTP probe via SuperSend's validator). Consumes global email verification credits (same pool as contact validation and CSV import).

Optional TeamId attributes the credit debit to a team for reporting; omit for org-level-only attribution.

The response includes email intelligence fields (risk score, flags, provider hints, network metrics) in the same payload as the SMTP result—one verification credit unlocks both.
