In order to quickly perform many tasks, ePACT runs them in the background. Once these actions are completed, you will receive an email alert to let you know that it has been successful or to alert you that a problem occurred.

These email alerts only go to the person who instigated the action and only for actions that involved 50 or more members. 
You can read more about the Account Activity Log here. 

You can view your account activity and their status by clicking on the "View" button next to Account Activity Log.
