Debug Mail: Local Email Testing and Debugging Tool

A mock SMTP server for email testing and debugging, allowing developers to locally test and debug email workflows without sending actual emails.

What is Debug Mail?

Debug Mail is an email testing and debugging application designed to help developers build and test email features in their software without actually sending emails. It works by providing a mock SMTP server that captures any email sent to it from the application being developed.

Some key features and benefits of Debug Mail include:

  • Catches all email sent to it, allowing developers to preview and debug email content, headers, attachments etc.
  • Provides a web interface to view a log of all caught email messages.
  • Lets you resend the same email multiple times during testing without duplicate deliveries.
  • Supports testing of email notifications, confirmations, receipts etc.
  • Saves time and development costs by eliminating the need to clean up test email data.
  • Available for Windows, Mac and Linux.
  • Free and open source tool with an MIT license.

Overall, Debug Mail simplifies the process of building and testing email functionality within applications by providing a configurable fake SMTP server to catch test emails. This allows rapid development without spamming real inboxes.
