Mass Notification Messages from GBCS

  • As of August 2019, Grand Blanc Schools has transitioned to a new mass notification system in an effort to better serve our families.  The new system, Blackboard Mass Notifications, will allow buildings to notify parents of important events and emergencies by one or more of these methods:

    • Phone
    • Email
    • Text Message (new for 19-20)
    • Push Notification* (new for 19-20)


    *In order to receive Push Notifications, users must have download the GBCS Mobile App and have subscribed to notifications from their building and/or the district.
