Connect your Postmark account to any AI agent to automate your transactional email workflows and template management with ease.

What you can do

  • Email Delivery — Send single, batch (up to 500), or bulk emails with full control over HTML/Text bodies, attachments, and metadata.
  • Template Management — List, create, edit, and delete email templates directly. Use the validation tool to ensure your syntax is perfect before sending.
  • Dynamic Content — Send emails using existing templates by injecting variables through the TemplateModel.
  • Tracking & Analytics — Enable open tracking and link tracking to monitor how recipients interact with your messages.
  • Bulk Operations — Handle large-scale distributions and check the status of bulk requests asynchronously.

How it works

  1. Subscribe to this server
  2. Enter your Postmark Server Token (and optionally your Account Token)
  3. Start sending emails and managing templates from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Developers — Send test emails and manage templates directly from your IDE without switching to the Postmark dashboard.
  • Marketing Ops — Quickly update email copy or validate template structures using natural language.
  • Support Teams — Automate personalized follow-ups or notification emails through AI-driven workflows.

See how to talk to your AI agent using Postmark.

Send an email from 'sales@company.com' to 'client@example.com' with the subject 'Meeting Follow-up' and a simple thank you message.

I've sent the email using `send_email`. The Message ID is 'abc-123' and the status is 'Submitted'.

List all the email templates available on my Postmark server.

I found 3 templates: 'Welcome Email' (Alias: welcome), 'Password Reset' (Alias: reset), and 'Invoice' (Alias: invoice).

Send a welcome email to 'newuser@gmail.com' using the template alias 'welcome-pack' and set the 'name' variable to 'John'.

Processing `send_email_with_template`... The email has been successfully queued for delivery to John.

Yes! You can use `send_batch_emails` to send up to 500 messages at once, or `send_bulk_emails` for larger distributions using templates and recipient variables.
