Frequently asked questions about the Postmark Alternative MCP Server
Can I use this server to actually send operational emails from my account?
Yes! The send_email and send_email_with_template tools will dispatch active live emails using your Postmark server configuration.
How can I debug a specific user reporting that they didn't receive an email?
You can ask the agent to execute search_outbound_messages or search_bounces using their exact email address. The agent will fetch the delivery log and status codes.
Do I need the Account Token or the Server Token to use this?
You only need the Server Token. Postmark divides workflows by servers (environments). Supplying the server token isolates this specific operational environment perfectly.
