This setting is configured on a per admin basis. So you can alert as many or as few admin users as you want regarding high spend activities by guests. In order to enable it for a specific admin, go to Settings>Admin Users>Specific Admin User and click on the applicable box as seen below. Note that you can also configure a similar setting for redemption thresholds through contacting your CS representative.
