About

This site provides web hosts, developers, and email administrators with free tools to diagnose common email delivery problems — SPF misconfigurations, missing DMARC policies, MX routing issues, and more. The tools are real and useful, even if the name is a joke.

The Tools

All tools are free to use. They run DNS-over-HTTPS queries via Google or Cloudflare resolvers and return structured, human-readable results. Results can be copied as plain text or exported as JSON.
