Your transactional emails are too important to end up in spam. Postject is the modern, developer-first infrastructure that guarantees speed, unmatched deliverability, and an API you'll actually love using.
We take the stress out of email infrastructure so you can focus on building great products.
Postject sits on top of one of the most trusted email infrastructures in the world. We vet senders to ensure your IP reputation stays spotless.
Keep your password resets lightning fast. We route your crucial transactional emails through separate streams from your marketing broadcasts.
Our API is designed for humans. No complex SDKs or 50-page XML documentations. Set up your domain, grab a key, and send JSON.
See exactly what happened to your emails. We automatically process bounces, complaints, and deliveries so you don't have to build your own webhook listeners.
No complex configuration. No XML. Just create, verify, and send.
Sign up and get your first server with a default transactional stream — ready in under a minute.
Add your sending domain and configure the DNS records we provide. We handle DKIM signing automatically.
Use our REST API with your server token. Send raw HTML or use templates with dynamic variables.
With simple HTTP endpoints, Postject fits seamlessly into any stack. Whether you're building in Node.js, Python, Go, or PHP, all it takes is a standard JSON request to start pushing your emails out to the world.
Plus, we handle the bounce management natively. No extra code required on your part.
