School Messenger is the contact system we use in the district for sending notifications to our parents/guardians, employees and affiliates. With this system, alerts are sent using email, SMS text messages, and phone calls. 

SMS Alerts: 

In order to receive SMS text messages to your cell phone, you must "Opt-in" to be sent messages. As parents and guardians, you may have already received a text message inviting you to "opt-in" to the service. If you have not opted in or do not receive the invitation, you may still use this free service!  To opt-in at any time from your cell phone simply text "Y" or "Yes" to 67587 (our school short code).  

Click here for detailed instructions on how to opt-in in English and Español along with additional Privacy information. We encourage everyone to opt-in as soon as possible to start receiving all alerts from Riverhead Central School district. 



There’s an App for that:

Go to to download the Blue SchoolMessenger mobile app for Apple and Android devices or use the web-based version from your Internet browser.  You must use the email address we have on file for SchoolMessenger.
