MailSlurper is a lightweight, web-based SMTP mail server written in Go that captures emails sent by applications during development. It stores messages in a database and provides a web UI for viewing them, letting developers test email functionality without a real mail server.
Use cases
- test email sending in local development
- capture emails from my app without a real SMTP server
- view emails sent during automated tests
- run a fake SMTP server with Docker
- inspect outgoing mail from a small dev team
When to choose
- you need a simple local SMTP sink with a web UI for development or testing
- you want a Docker-friendly mail catcher for individual developers or small teams
When to avoid
- you need a production mail server with real delivery, relaying, or spam filtering
- you require enterprise features like high availability or large-scale mail routing
