DESCRIPTION

Email validation API / email deliverability check / email verifier. Validates address syntax, checks MX reachability, detects disposable/temp-mail domains and role accounts, and summarizes SPF/DMARC/DKIM posture. This endpoint does not send email and does not probe the recipient mailbox; it is DNS + public blocklist only.
