Email Deliverability Check

Checks whether an email address is likely to be deliverable and how risky it looks.

Overview

Checks whether an email address is likely to be deliverable and how risky it looks. 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. Use it as an email deliverability verification API, email spam check, spam-folder risk scorer, email validation/verifier/checker, inbox readiness score, MX lookup, disposable email risk check, role-account detection, or SPF DMARC DKIM posture report.
