}'Why developers choose LiteStartup
We built the email platform we wished existed.
The Problem
Email APIs are bloated
Most email platforms force you to install heavy SDKs, learn proprietary abstractions, and manage complex configurations before you can send a single email.
Our Solution
One REST endpoint. Zero SDKs.
Send emails with a single HTTP POST. Use any language, any framework. No vendor lock-in, no proprietary libraries to maintain.
The Problem
Separate tools for every use case
Transactional emails in one service, marketing in another, support in a third. Managing multiple vendors drains engineering time.
Our Solution
Everything in one platform
Transactional API, marketing campaigns, inbox, live chat, and help desk — all under one API key, one dashboard, one bill.
The Problem
No visibility into delivery
You send an email and hope it arrives. When it bounces, you find out days later from angry users.
