Stellar deliverability

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.

Promotional and transactional emails never mix

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.

Analytics you actually need

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.

Create your account

Sign up and get your first server with a default transactional stream — ready in under a minute.

02

Verify your domain

Add your sending domain and configure the DNS records we provide. We handle DKIM signing automatically.

03

Use our REST API with your server token. Send raw HTML or use templates with dynamic variables.
