CredMail
Finds what's wrong with your email — and fixes it for you
CredMail checks whether your domain and email list can actually reach the inbox: SPF, DKIM, DMARC, 107 individually audited blacklists, BIMI, and MTA-STS. Four AI agents go further: generate the exact DNS fix, explain failed emails, give a launch go/no-go, and plan your sending ramp-up. Free tools cover more than the paid tier of a 22-year-old category leader. Plans start at $9/mo. Free CLI: `npx credmail check yourdomain.com` — no signup.
Hey Product Hunt 👋
Built CredMail because every "check your email deliverability" tool I found either gave raw DNS data and left me to figure out the fix myself, or cost more than my hosting bill.
Funny story on trustworthiness: a few weeks ago someone questioned our own domain's score, so I actually audited all 107 blacklists we check instead of getting defensive. Found one that's been dead since 2003 and was returning false positives on every single domain, plus a handful of others that were structurally incapable of ever giving a real answer. Fixed all of it — our own score is a more honest 88 now, not a padded 92.
Free to check your own domain right now, no account needed. Would genuinely love to know what you find — and if something looks off, tell me, I'll actually go look.
