About

Most deliverability tools either spit out a score and stop talking, or assume you're already an expert. Email Health Pro does neither. We grade every dimension that matters, and the Learn hub explains what each one means and how to fix it.

Why we built this

Existing checkers have a blind spot: they reject anything that fails authentication or trips a content rule, then tell you nothing about what would have come next. Real mailbox providers don't bounce — they accept, then quietly route to spam. If your message would have failed SPF and then been quarantined for a bad List-Unsubscribe header, you'd never learn about the second problem until you fixed the first.

Email Health Pro grades everything in a single pass, so you see the whole picture on the first send.

Why never reject?

Real mailbox providers like Gmail and Microsoft are opaque about why a message ended up in spam. Email Health Pro flips that around: we accept everything and report what we'd have done. Your test message is never bounced for failing SPF or for a high SpamAssassin score — it's just graded.

Free during the beta

Email Health Pro is free during the beta. A free tier for one-off checks will always exist.
