Validate an email address without sending mail. POST {"email":"[email protected]"} to get one verdict — deliverable, undeliverable, disposable, role_address, typo_suspected, or invalid — plus a 0-100 deliverability score. Checks RFC-5322 syntax, live MX records, disposable/throwaway domains, role mailboxes (info@, support@), and typos of common providers (gmial.com -> gmail.com). Returns MX provider, per-check provenance, and a verdict hash. No SMTP probe.Overview
