If you are running local applications, internal microservices, or custom scripts, you often just need a simple way to send email notifications without configuring a bloated, traditional Mail Transfer Agent (MTA) like Postfix.
That is why I created ZeroSMTP – a lightweight, open-source SMTP relay gateway designed to keep things fast, simple, and frictionless.
Why ZeroSMTP?
Lightweight & Fast: Built for straightforward email relaying without heavy configuration overhead.
Open Source: Fully transparent code that you can inspect, modify, and self-host easily.
