BEFORE
"Check, fix and monitor your domain's DNS and email authentication. Look up records, see whether a change is live across six locations, read registration and expiry, and diagnose SPF, DKIM and DMARC, with engine-validated DMARC records when the evidence supports a change. Check whether a domain is set up to show its logo in inboxes (BIMI), mailbox by mailbox. Send a test email to a single-use address and see how that real message authenticated: SPF, DKIM and DMARC alignment, message hygiene and blocklists, with an itemized score out of 10 and an estimate, per mailbox provider (Gmail, Yahoo, Outlook, Apple), of whether the message is accepted and reaches the inbox. Connect a DNS Doctor account to monitor the domains you verify: DMARC aggregate reports read for you, alerts on new senders and record changes, and whether the report evidence supports the next DMARC policy step, including what is still blocking it. You publish every record yourself.\n\nScan a domain for email authentication (SPF, DKIM, DMARC), mail routing (MX), DNS health, blacklists and domain and SSL certificate expiry, and see which sender requirements of Gmail, Yahoo, Outlook and Apple the domain's DNS meets. Read A, AAAA, CNAME, MX and TXT records, including SPF and DMARC, from the domain's own nameservers, with a plain done, wait or edit answer when you check a change you just published, see whether a change has reached resolvers in six locations, check reverse DNS for a mail server, count SPF lookups, audit the third-party includes an SPF record trusts, and read a domain's registration: registrar, expiry, nameservers and locks. Check which look-alike names close to a domain are registered and resolve, stated as facts and never labelled malicious; any takedown report is filed by the owner from the DNS Doctor dashboard.\n\nDMARC records are generated and validated by a deterministic engine that follows the RFCs. The AI writes the explanation, never the record. SPF is diagnosed but never rewritten, because a changed SPF record can silently cut off a real sender. Nothing is applied to your DNS: you publish every record yourself.\n\nConnect your DNS Doctor account to work with your monitored domains from ChatGPT: see every domain in the account with its next step, add a domain, check its ownership record, review watched look-alike names with their threat scores, and read the alerts DNS Doctor raises for record changes, expiry, blacklisting, registrar or nameserver changes and new email senders seen in DMARC reports. It also tells you when that report evidence says it is safe to move DMARC from none to quarantine and then to reject."

"Find out why email from your domain lands in spam, check whether a DNS change has reached resolvers in six locations, and keep watch on your domain's email, DNS and website. Ask in plain words and get a clear answer, with the exact record to publish when a fix needs one.\n\nWith DNS Doctor you can:\n• Check email authentication: diagnose SPF, DKIM and DMARC, mail routing (MX), blocklists, domain and SSL certificate expiry, and which Gmail, Yahoo, Outlook and Apple sender requirements your DNS meets.\n• Check a DNS change: read A, AAAA, CNAME, MX and TXT records from the domain's own nameservers with a plain done, wait or edit answer, and see whether the change has reached resolvers in six locations on four continents.\n• Test a real email: send one message to a single-use address and see how it authenticated, with a score out of 10, a per-provider estimate of acceptance and, when available, of inbox placement.\n• Look up a domain: registrar, expiry, nameservers and locks, reverse DNS for a mail server, SPF lookup count and the third-party includes your SPF trusts.\n• Check whether your domain meets each mailbox provider's requirements for showing its logo in the inbox (BIMI), and which look-alike names close to your domain resolve, stated as facts and never labelled malicious.\n• Move DMARC to enforcement safely: DMARC records are generated and validated by a deterministic engine that follows the RFCs. The AI writes the explanation, never the record.\n\nMonitor the domains you verify by connecting a DNS Doctor account:\n• Website uptime checked from five locations on four continents (US West, US East, Brazil, South Africa, Germany), with an email when the site goes down.\n• DMARC aggregate reports read for you, alerts on new senders, record changes, expiry, blacklisting and registrar or nameserver changes.\n• When the report evidence says it is safe to move DMARC from none to quarantine and then to reject, and what is still blocking it.\n• From ChatGPT: list your domains with their next step, add a domain, check its ownership record, read the alerts, and review watched look-alike names with their threat scores.\n\nSPF is diagnosed but never rewritten, because a changed SPF record can silently cut off a real sender.
