Mailpit is a lightweight, zero-dependency email and SMTP testing tool for developers that acts as a local SMTP server and captures outgoing mail. It provides a modern web UI to inspect messages, plus a REST API, POP3 server, and features like HTML compatibility checks, link checking, spam analysis, and message relaying.
Use cases
- capture emails sent by my app during local development
- test email sending without sending to real users
- run an SMTP server for integration testing
- inspect HTML emails and check email client compatibility
- query captured emails via an API in automated tests
- replace MailHog for email testing
- check spam score of my emails with SpamAssassin
- view test emails in a web interface
When to choose
- you need a fast, low-memory local SMTP catch-all for development or CI
- you want automated email assertions via a REST API
- you need HTML/link/spam analysis tooling for email testing
- you want a maintained MailHog replacement with Docker images
When to avoid
- you need a production mail transfer agent or real email delivery
- you need a hosted/team email testing service with shared inboxes (though Mailtrap integration exists)
- you require full IMAP support
