I saw this in a post:
Without Addon (only link, content of the ticket is not included):
- go to System
- Create an Event - Select a notification template
- Add a post function to the workflow "Fire Event"
- go to the Notification scheme and select the event you have just created and select "Single email address"
But I don't see a menu item to create an event.
Also, I wonder if an automation would work, if there were a way to use an email address that automatically selects the assignee.
