Welcome to the Make community!
To do this, you can use the Webhooks “Custom mailhook” module —
Triggers when mailhook receives data.
For more information about the “Custom mailhook” module and Webhooks app, see the corresponding Integrations page and the Help Centre documentation.
Hope this helps! If you are still having trouble, please provide more details.
