Domain Doctor

Public configuration, practical answers.

Domain Doctor checks a domain’s public DNS, email authentication records and HTTPS setup. It returns what it observed, what needs attention, why it matters and practical next steps.

Ask in ChatGPT

• “Check the domain configuration for example.com.”
• “Emails from my domain are going to spam. Check the public email setup.”
• “Does my website have a valid HTTPS certificate?”

Give a public domain. You can focus on email or website checks. To check DKIM, supply a selector from your email provider or a DKIM-Signature header. No account or password is needed.

What a check can tell you

DNS address and nameserver records, MX routing, SPF syntax and dependency risks, DMARC policies, known DKIM keys, certificate validation and HTTP redirects. A check is a snapshot and may be incomplete.

Domain Doctor does not send emails or change your records. Public configuration cannot guarantee delivery, security or the legitimacy of a business.

Data shared during a check

DNS names are sent to Google Public DNS. Website checks send bounded HEAD requests to the public website. Read the privacy policy before using the service.
