To update your community notification settings, click on your Username in the right corner of the global header to open your user menu, and select My Settings:
Navigate to My Settings > Subscriptions & Notifications > Notification Settings.
In the General Settings, select which types of notifications you would like to turn off and choose the default behavior for your activity.
Under the Email Notifications heading, select how often you would like to be notified of each activity (Never, Immediately, in a Daily Digest, or in a Weekly Digest).
