The email address that was verified.
status
Required
Overall verdict. valid = mailbox accepts mail; invalid = will bounce; risky = deliverable but low-confidence (catch-all, role, or major-provider that lies at SMTP); unknown = could not be determined (timeout/block). Unknown results are not charged.
reason
Required
Machine-readable reason code, e.g. bad_syntax, no_mx, mailbox_not_found, catch_all, disposable, role_account, provider_unverifiable, smtp_timeout, smtp_blocked.
score
Required
Deterministic 0-100 deliverability score derived from the checks. Higher is safer to send to.
