Free Email Flow Grader

Grade your app’s emails in 10 minutes.

We give you a temporary address. Sign up for your own app with it, trigger a password reset, and we grade every email that arrives: speed, authentication, broken links, leaked merge tags, and the emails that should exist but don’t. No account needed.

Shown on your score card so people know what was graded.

Only if you want to hear when Flowproof launches. We will never require it to see your results.

Quick human check, so nobody uses the grader to mint throwaway addresses:
