Great news!
You can now install the Mailtrap MCP to send emails (Email API + Sandbox) and manage your templates directly from the Claude desktop app.

1. In Claude, go to Settings → Extensions → Browse Extensions.

2. Install Mailtrap MCP.

3. Add your API key (required) and, optionally, your account_id and sandbox_id if you want to send emails to a sandbox and/or manage your templates.

After you can run such prompts like:

• Send an email to xxx with yyy subject using Mailtrap

• Create a template in Mailtrap

• Some other examples are in our readme
