In Orbit Asset you have the option of determining how often you receive email notifications for changes to tasks, comments added, assignments of tasks or cases made. 

These emails can be turned off, sent after every change in the system or a recap of all changes can be sent to you once completed. 

In order to do this, you need to access the mail preferences tab which is found under the user profile symbol shown below.

Once you've clicked on 'Edit my profile', you will see the option to change 'Mail preferences' with different ways of sending emails:

 Don't forget to click on Save once changes are made.
