First-class
developer experience

We are a team of engineers who love building tools for other engineers.Our goal is to create the email platform we've always wished we had — one that just works.

Test Mode

Simulate events and experiment with our API without actually sending real emails to real people.

Modular Webhooks

Receive real-time notifications directly to your server. Every ping is tracked, delivered, opened, and clicked.
