In the InstaTeam app each event will have alerts and reminders that are sent as push notifications. All users have full flexibility to specify which notifications they want to keep on and which notifications they want to turn off.
Along with push notifications, emails are also sent to team members to double check the team members get it.
Each user can customized the push notifications that they want to receive. For example, a player may choose not to receive email notifications, but only push notifications on the smartphone. Another user may want to turn off schedule-change alerts.
