About:
Mailpit is a local mail testing tool that acts as a fake SMTP server with a modern web UI. It captures outgoing emails for inspection without sending them to real recipients, providing a safe environment for development and testing. Its API also enables automated testing of email functionality within CI/CD pipelines.
Key Features:
  • Web-based UI for viewing and inspecting captured emails
  • API for automated testing and integration with CI/CD
  • Supports TLS and authentication for realistic testing scenarios
  • Message search and filtering capabilities
  • Lightweight and easy to run locally
Use Cases:
  • Developing and debugging email-sending functionality in web applications
  • Automated testing of email workflows in continuous integration pipelines
  • Reviewing HTML email templates and attachments before production
Alternatives:
  • MailHog – MailHog is a similar tool but is no longer actively maintained; Mailpit offers a more modern UI and active development.
