Email verification

Email verification. Check email syntax, DNS and MX records, disposable providers, role addresses, free providers and SPF/DMARC presence. Returns likely-deliverable, risky, undeliverable or invalid with reasons. No message is sent and the mail server is not contacted. These are DNS and syntax signals, not proof that a mailbox exists or accepts delivery. Use before sending mail or saving a signup.
