Each PTO has an email list that you may subscribe to. Many organizations use Buzzable, powered by Sendy. Click here to subscribe or unsubscribe to buzzable lists.
The district also has a email list called school messenger (replacing SNN). Messenger is operated by the superintendent's office and sends district-wide email pertaining to time-critical events (snow days, cancellation of after school activities, etc), events related to the school board (budget information, etc), and official notifications from the school district (school lunch program, meetings with superintendent, etc.).
