Northern Trail Outfitters has created child business units (BU) for their different regional offices.

Using "Define Subscriber Filter" at the BU level allows you to limit subscribers based on Profile Attributes like "Region." Each child BU will then automatically filter the All Subscribers list and other sendable data based on that Region, ensuring users in a BU can only access subscribers for their specific region.
