Integration details

Description

Give Domain Doctor a public domain to check DNS records, inbound email routing, SPF, DMARC and HTTPS certificate configuration. Get evidence-backed findings with importance, explanations and practical next steps. Known DKIM selectors can be checked when you supply them. Use it to investigate email setup problems, spam symptoms or website certificate warnings. It performs read-only public checks, does not change records or send emails, and cannot guarantee email delivery, security or business legitimacy. DNS query names are sent to Google Public DNS; website checks send bounded HEAD requests to public servers. No account is required.

Tools

1 tool agents can invoke

Check a supplied public domain’s DNS, email authentication and/or HTTPS configuration using live read-only checks. Use for troubleshooting missing email, spam symptoms, SPF/DMARC setup, MX routing or TLS certificate problems when the user supplies a domain. Ask for the domain if missing. Optional DKIM selectors must come from the user/provider; do not invent selectors. Sends DNS query names to Google Public DNS and, for web/all scope, HEAD requests to the public website. Returns evidence, severity, why findings matter and practical fixes. Does not send email, change records, guarantee delivery, inspect site content or establish business legitimacy. Do not use for drafting email, generic definitions, domain purchase/valuation, private targets or port scanning.
