Generate and test live email code in Cursor

Write your backend mailer code while Cursor pulls live data from your Mailgun account. Your agent uses `get_templates` to fetch actual HTML layouts so you can write code against real template variables. Test your sending logic on the fly. The agent triggers `send_email` using your sandbox domain, letting you verify the actual API payload without writing throwaway test scripts.

Run real-time validation with this MCP Server

Clean your test databases or user sign-up mocks inside Cursor. This MCP Server lets your agent run `validate_email` against any list of addresses in your workspace files. The validation tool checks MX records and syntax, allowing the editor to flag bad data before you write it to your database. No more hard bounces during local development.

Track delivery logs without leaving your codebase

If an integration test fails to deliver, ask Cursor to run `list_logs` to see what Mailgun received. You can view raw event status, open rates, and drop reasons right next to your code. If a test address gets blocked, run `list_bounces` to find the suppression. You can then execute `delete_bounce` to clear the block and resume testing your signup flows.
