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.
