Email validation
Verify email addresses
Queue an SMTP mailbox probe for lead addresses, raw addresses, or both. Results are written back onto the leads as email_status, email_provider, email_is_role and email_validated_at.
Pass estimate_only to price the run without queueing it. You are only charged for probes that actually run — cached results and addresses rejected by the cheap pre-check are free.
Requires the leads:validate permission, deliberately separate from write so a general-purpose key cannot run up a validation bill.
