More Details Connect to Claude

Connect your Postmark server to any AI agent to fully orchestrate and analyze your transactional email pipeline.

What you can do

  • Send Emails & Templates — Send transactional emails directly from the agent using pre-configured Postmark Templates or Raw HTML.
  • Investigate Bounces — Read the server bounce log to find out why specific recipients failed delivery (Hard Bounces, Blocks).
  • Template Management — Fetch and review the raw body of your templates to ensure dynamic variables align flawlessly with code.
  • Outbound Analytics — Review message stream stats, open rates, and general health metrics directly via chat.

How it works

  1. Subscribe to this server
  2. Enter your Postmark Server Token
  3. Gain complete control of your application's email notifications from Claude, Cursor, or any MCP-compatible environment

Who is this for?

  • Software Engineers — Trigger template dispatches from the terminal and review server logs to debug application email flows seamlessly.
  • Product Teams — Monitor bounce rates and verify the visual layout of critical system emails without accessing the Postmark UI.
  • System Admins — Quickly query delivery analytics and trace email endpoints for quick operational overviews.

Check the bouncing metrics for our transactional emails.

I've analyzed your bounce metrics. The server currently has 14 Hard Bounces and 3 Soft Bounces within the query scope. Overall health looks good! Want me to list the specific emails?

Can you fetch the HTML body layout of our 'Welcome' template?

I found your 'Welcome' template (ID: 809214). It expects three variables: `first_name`, `action_url`, and `support_email`. The HTML renders a classic logo-centric email layout.

Send a standard test email to alice@example.com using our current Postmark setup.

The email has been processed! Postmark returned success mapping with a Message ID `f8a847a9-2169-45e0-...` indicating instantaneous dispatch.

Yes! The `send_email` and `send_email_with_template` tools will dispatch active live emails using your Postmark server configuration.
