What it does

Developer-first email platform for testing, sending, and shipping reliable campaigns faster.

Detailed overview

Mailtrap gives teams a safer, more technical way to test and ship emails, then run marketing sends from the same ecosystem. It blends developer infrastructure with actual email marketing functionality. Most marketers know the name only as a testing tool, not as a broader email platform, useful, current, and unusual enough to deserve a slot. The homepage shows 150,000+ monthly active users, a new official CLI, a public roadmap/changelog, and multiple 2026 testimonials and updates. Built for developers, product teams, and technical marketers.
