👋 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...
MailTestDebug 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.
