Each user can choose their own notification preferences. Admins do not have the ability to edit a user's notifications on their behalf, only the user can do it themselves. 

To adjust your notifications, visit your Settings → Personal → Notifications:

Enable the notifications you'd like to receive from Groove by checking (or un-checking) the boxes next to any of the notification options.

Click Save Changes and you're all set!

Please note: there is no setting for @mention notifications, and they cannot be disabled.
