  title: Mailtrap Email Sandbox Messages API
  description: The Mailtrap Email Sandbox API provides a safe email testing environment to inspect and debug emails before sending to real recipients. The API supports sending test emails into virtual inboxes, then retrieving, analyzing, and managing those captured messages. Sandbox endpoints cover messages, inboxes, projects, spam reports, HTML analysis, and raw or formatted message bodies.
