Show HN: I built a tool that diagnoses your email deliverability (opens in new tab)

As you may know, Google is rolling out bulk sender guidelines that go into effect Feb 1 (that’s this Thursday)

Your deliverability could be impacted so we made this tool.

Here’s how it works:

1. Send an email to the generated email address 2. Review your results

That’s it. The generated /results page is also accessible publicly so you can share with your team in case you're not the one with permission to add or modify records.

You can view an example of a passed test here: https://bounce.doctor/results/example

We currently check for valid DKIM, DMARC, SPF, List-ID and One-click Unsubscribe. We plan to extend this tool in the future as well but it will remain free and accessible without an account.
