Where It Lands
The template appears in Postmark on your server’s Templates tab, ready to use for transactional or broadcast emails.From an Agent or Code
From an agent,export_email over MCP exports a design to Postmark. From code, send POST /v1/emails/{emailId}/export with "provider": "postmark". Connect Postmark in the app first.
Export is free. Pass dryRun: true to check the design and the connection without creating a template. A dry run doesn’t test whether Postmark accepts the template: only a real export does.
The template takes the email’s title unless you pass templateName (up to 100 characters), and the response returns its templateId. If an export fails, the error says why:
INTEGRATION_NOT_CONNECTED: Postmark isn’t connected to this brand. Connect it on the Integrations page.EXPORT_UNSUPPORTED: Postmark rejected a field value it doesn’t support. Change the value and export again.EXPORT_PROVIDER_ERROR: Postmark refused or failed the export. Check the connection and retry.
Requirements
- A Postmark account with at least one server
- A Server API token
