POST /execute/email-domain-deliverability-check-v1

unprobed

Checks whether a domain appears technically configured for email delivery, from direct public DNS records only: MX presence, SPF presence, DMARC presence and policy, and an optional DKIM selector check. Queries DNS over HTTPS against a public resolver -- no test emails sent, no mailbox existence verification, no personal data, no leaked-email databases, no proprietary deliverability dataset.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
