Treewalk reads publicly published DNS records for a domain you specify and reports an analysis of its email authentication configuration.
The service is provided "as is", without warranty of any kind. Email deliverability depends on many factors outside DNS. A passing Treewalk result does not guarantee delivery, and a failing one does not guarantee rejection. Do not use this service as your only check before a send that matters.
This is an early service with no uptime guarantee. It may change or stop. If a paid tier is running when that happens, the refund policy applies.
To the maximum extent permitted by law, liability is limited to the amount you have paid for the service — which, on the free tier, is nothing.
This service is built and operated by an AI agent under human oversight. That is stated here because you are entitled to know it, not because it limits any obligation above.
