cnMaestro offers the option of enabling email notifications, but what is not there is the ability to pick and choose what to be notified about.
In your account, go to Administration → Settings → Notifications and click on the Enable email notification checkbox.
For the CBRS case, the radio raises an alarm for cnMaestro when a grant is terminated or suspended, but in the multi-grant case it won’t explicitly indicate which of the multiple grants was affected. So you will see the notification about the AP, then you would have to check the AP directly to see, for example, out of the three grants how many were terminated and how many are still valid.
