Email deliverability verification / email validation / email verifier / email checker / MX lookup / disposable email risk / role-account detection / SPF DMARC DKIM posture. Validates syntax, checks whether the domain can receive mail, scores domain-level deliverability risk, detects temp-mail/disposable domains, flags role accounts, and summarizes SPF/DMARC/DKIM records. No mailbox-level SMTP probing; privacy-safe DNS + public blocklist only.
