Secure EmailAUDIT
Audit an email address: domain TLS, MX records, SPF/DMARC presence, common disposable-provider flags, and a ready-to-paste mailto: link. All checks run live in your browser using Cloudflare DNS-over-HTTPS.
What does each signal mean?
MX records tell the world which servers receive mail for the domain. No MX → the address can't accept mail. SPF lists which IPs are allowed to send from the domain (catches simple spoofs). DMARC tells receiving servers what to do when SPF/DKIM fails. A domain with all three is materially harder to spoof than one with none.
Disposable flags addresses from throwaway providers (mailinator, tempmail, …) — useful when an email address is supposed to identify a real human. Role address flags shared inboxes (info@, support@, admin@) which can't be tied to a single recipient.
