Connect Postmark to ChatGPT

To use Postmark in ChatGPT, connect your Postmark account in Manyplug and add Manyplug to ChatGPT once. ChatGPT then gets 6 Postmark tools, for example: “Send an email”, “Send a template”, and “Templates”. It takes about 5 minutes and works on the free plan.

Questions

Can I connect two Postmark accounts to ChatGPT?

Yes. Connect each one in Manyplug under its own name, for example Work and Personal. ChatGPT can use one of them or all at once.

Will ChatGPT change anything in Postmark without asking?

By default these actions wait for your approval before they run: “Send an email” and “Send a template”. Other changes follow your rules, which you can make stricter per account.

Do I need an official Postmark MCP server for this?

No. Manyplug connects to Postmark itself with a key or app password you paste into its form, and gives ChatGPT the tools through one MCP address, together with your other services.

Is it free to connect ChatGPT to Manyplug?

Yes. New workspaces get 14 days of Pro free, then the free plan keeps going with 150 actions a month and up to 3 connected accounts. No card needed. Paid plans start at $5 a month.

Does ChatGPT see my passwords or API keys?

No. Keys are entered on Manyplug’s own pages, stored encrypted with a separate key per account, and the AI only receives tool results.
