To target all customers who have registered to receive push notifications, Northern Trail Outfitters can use two ways to create this segment:
Using Mobile Studio, create a Mobile Push Filtered List then filter on the MobilePush Demographics attribute group. This is a user-friendly tool that allows marketers to segment their mobile push audience based on criteria and conditions without coding.
Using Automation Studio, query the _MobilePushDemographics Data View and save this to a data extension. This is a more advanced tool that allows marketers to segment their mobile push audience using SQL queries and data views.
Using Journey Builder or Contact Builder are not ways to create segments for mobile push audiences, as they are used for different purposes.
