POSTJECTDOCS

Introduction

Welcome to the Postject API. Postject is a complete email infrastructure platform built for developers. We own and operate our own email servers, routing infrastructure, and delivery network to provide you with fast, reliable transactional email delivery at scale.

Why Postject?

The email industry is crowded with heavy, bloated marketing suites. Postject provides a lightweight, developer-first platform with our own dedicated email infrastructure, giving you full control over delivery, performance, and reliability.

  • Own Infrastructure: We control the entire email stack from API to inbox delivery.
  • Zero Setup: Send immediately from a hosted subdomain while you verify your own.
  • API-First: A clean, JSON-perfect REST API designed for developers.
  • Full Visibility: Real-time delivery tracking, webhooks, and comprehensive analytics.
  • Security Built-In: HMAC webhook signing, 2FA, IP whitelisting, and anomaly detection.
