Login to School Messenger

SchoolMessenger is a web-based notification solution that allows the district to send messages by phone or email to parents and staff.

Campus Administrators (Principals and APs): 

  • To gain access to SchoolMessenger, Campus Administrators need to review all training materials found at the bottom of the page first
  • Please contact Michelle Reyes at for support with access/login information
  • All schools have login credentials to schedule and record their own messages
  • See Quick Guide below for step-by-step instructions to set up a message
  • Use for your URL

Departments Requesting a SchoolMessenger Message:

  • Departments must complete a form to request an automated message for students/parents and staff
  • Click here to download the form
  • Request must be submitted a minimum of five business days before the first automated message is scheduled to be sent
  • Email the completed form to Michelle Reyes at
  • Script in English and Spanish must be included with the request (if message is for students/parents)
  • Departments may request a maximum of three messages per event. Of the three messages, no more than two can be scheduled within a week of the event
  • Please avoid the dissemination of non-essential information that could more appropriately be conveyed through other communication vehicles
  • Please avoid overuse of the system for the dissemination of non-essential messages that could potentially overburden recipients (message fatigue)
  • Messages should be under 40 seconds in duration
  • Contact the Communications Department for support in developing a communications plan for your event utilizing other channels of communication beyond SchoolMessenger

For questions or comments, please contact the Office of Family and Community Engagement at (210) 554-2265 or (210) 554-2210.
