To change the notifications you receive from the InsightStore, click on Notifications to the left of the Basic Information or Password screens.
The system defaults to sending immediate notifications when you're added to a user group. The same is true when a multiscore report, dashboard, scorecard, segment, or file is shared with you or when a question's response quota is met. You can change those and other notifications to be sent Hourly, Daily, Weekly, or Never.
You will need to hit Save before any changes take effect.
