Domain Doctor
ChatGPT pluginCheck DNS, email and HTTPS
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.
