We started Postject because sending a simple transactional email shouldn't require a PhD in SMTP protocols. We believe every developer deserves infrastructure that just works.
Email is the backbone of every application. Password resets, welcome messages, invoices, and alerts. They all depend on reliable delivery. Yet most email APIs are over-engineered, expensive, or both.
We built Postject to change that. One API call. Instant delivery. Transparent pricing. Whether you're an indie hacker shipping a side project or a growing startup scaling to millions of sends, Postject grows with you.
These aren't just words on a page. They're the principles that guide every line of code we write and every decision we make.
Every millisecond matters. We optimize our infrastructure relentlessly so your emails reach inboxes in seconds, not minutes.
We vet every sender on our platform. Your IP reputation stays pristine because we refuse to compromise on deliverability.
From Lagos to London, São Paulo to San Francisco. We price fairly and build infrastructure that works everywhere.
No 50-page XML docs. No bloated SDKs. Just clean JSON, clear errors, and an API that feels like it was built by developers, for developers.
The engineering principles behind every decision we make.
Every feature starts as an API endpoint. The dashboard, CLI, and MCP server are all built on the same public API you use. No hidden internal endpoints.
Delivery rates, latency, bounce rates, reputation scores. If it affects whether your email reaches the inbox, we track it and surface it to you.
We build email infrastructure, not a marketing suite. Every feature we ship serves one purpose: getting your emails delivered reliably and fast.
Regional pricing, local payment methods, and infrastructure optimized for delivery worldwide. We don't treat emerging markets as an afterthought.
