We added this question and answer to our FAQ:
How do I turn off "Don't forget your upcoming events!" emails?
SportsEngine (who makes the software that runs our website) has added a new feature that sends notification emails for team practices and games. Unfortunately they have not (yet) given us the ability to turn them off by team or for all parents. Each parent or team manager must do this individually.
Update: SportsEngine has created a video explaining how to turn the notification emails off: share.vidyard.com/watch/wfUAwVevFX9ezkEqk4M9Z9
If this is not clear, contact SportsEngine for instructions on turning these emails off is via online chat. Go to their Contact Us page (https://help.sportsengine.com/customer/portal/emails/new) and click the START LIVE CHAT button.
As soon as anything changes we will post an update.
