Debug email deliverability with 11 checks
SPF ✅ DKIM ✅ DMARC ✅ — yet your emails still land in spam? Most tools just say "DKIM failed" without explaining WHY. MailTest goes deeper: 11 technical checks + actionable insights that show you exactly what's broken and how to fix it. Self-hosted, open source (after 100 users), built for developers who need real answers, not just red/green checkmarks. Try it free: 3 tests/day, no credit card.

"👋 Hey Product Hunt! I'm Sabahattin, co-founder at Scuton, building from Baku. **Why I built MailTest:** 3 months ago, I was debugging why our transactional emails kept hitting spam. SPF passed. DKIM passed. DMARC passed. Every tool said "✅ All good" — but Gmail still marked us as spam. Turns out: most email testing tools only check IF your records exist, not WHY they're failing in real-world scenarios. **What MailTest does differently:** ✅ 11 deep technical checks (not just SPF/DKIM/DMARC) ✅ Actionable insights — not just "DKIM failed", but "Your DKIM selector is missing, here's how to fix it" ✅ Self-hosted — your email data never leaves your infrastructure ✅ Real-time analysis — send test email, get results in seconds ✅ CI/CD integration — block deployments if deliverability drops **Current status:** - Free tier: 3 tests/day (no credit card) - Pro: $19/mo Early Access (200 tests/mo) - Open source release planned after 100 users (transparency commitment!) **What I need from you:** - Try it and tell me what breaks 🐛 - What checks am I missing? - Would you use this in your CI pipeline? Built with NestJS + Next.js 15. Self-hosted via Docker Compose. 👉 Try it: https://mailtest.scuton.com Thanks for checking it out! 🚀"
