What is the Postmark MCP Server?

Connect your Postmark server safely to any AI agent, granting it the ability to dispatch transactional emails, debug delivery failures, and inspect mailing architectures directly via conversational prompts.

What you can do

Send Emails & Templates — Command the AI to dispatch text-based emails or trigger rich HTML messages using pre-existing Postmark templates (send_with_template)
Inspect Bounces & Logs — Ask why an email failed. The AI can pull exact SMTP traces (get_bounce_logs) to explain spam rejections or DNS timeouts
Monitor Delivery Stats — Retrieve precise operational health data, mapping open rates and physical bytes sent across massive volumes
Manage Configurations & Templates — List active webhooks spanning your routing, edit server names, or safely clean up legacy template layouts

How it works

Subscribe to this server
Enter your Postmark Server Token
Start managing outbound communications natively in Claude, Cursor, or your preferred MCP client

Forget logging into dashboards to copy-paste trace IDs. Ask the model to 'find the latest bounce logs' and watch it dissect the 5xx errors for you.

Who is this for?

Backend Engineers — quickly check explicit webhook constraints or edit server settings on the fly
Support Teams — investigate exact reasons for "hard bounces" mapping physical UUIDs when users complain about missing emails
QA Testers — effortlessly trigger test templates and read precise delivery confirmation metrics

FAQ

Frequently asked questions

Can the AI send emails dynamically using my existing templates?

Yes. Using send_with_template, you merely tell the AI the template ID and the JSON parameters (Template Model). It perfectly injects the data into your Postmark layouts.

Is it possible to debug a complex email bounce natively inside Claude?

Absolutely. First command list_bounces to find failing message UUIDs. Then ask the agent to run get_bounce_logs on that UUID—it will interpret the pure SMTP error code for you naturally.

Which Postmark token should I use?

This MCP server uses the Postmark Server Token. Each Server in Postmark functions as an isolated environment (e.g. Production Server vs Staging Server).
