e_filed, setAlert, Route Data

When we use setAlert in the API to register for e_filed notifications, is an alert sent when the original flight plan is filed, when ATC provides official clearance for the route or both?

For example, a user files a flight plan with one route.
ATC then reviews and changes the route, providing clearance for the new route, but not the original filed route.

How many alerts would be received?
