Notifications
Login to the Domain Manager and go to Account details Notifications
This page shows an overview of all notification rules that are created by you and your users.
Various domain and other processes will trigger notifications. Some will be just a message of the completion of the process; others will require you to act in order to complete or go to the next step of a process. Notifications are event-driven messages to inform you about the changed status of an object in your account. 
Use the filters to search for specific processes. By clicking the checkmark in front of a notification you will ack notifications so they will be removed.
