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

1. Subscribe to this server
2. Enter your Postmark Server Token
3. 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
