For example, an fashion company with 5 different sub brands in one BU.
All subscribers enter from Service Cloud into one master DE. Each brand has a column in this master DE indicating if the subscriber opted in for that brand. I cannot change this process, as its maintained by another team in a different region.
However, i can create a new DE and use automation studio to filter the subscribers into different tables if i want. But for now they all exist in one master DE.
Marketing activities are executed per brand, no campaigns are sent to multiple brands. Campaigns do not overlap.
Now i want to build a data model in Contact Builder using Attribute Groups, but I have doubts about if to create new populations or not.
Should i just create an attribute group and link the master DE to the default model? Doing this makes all subscribers from all brands part of the same model.
Or Should i create a different population for each brand and create a separate model per brand? If so, I have read the Salesforce recommendation to create up to 3 populations maximum?
Brand 1 has +1.500.000 subscribers
The other have way less, like below 200.000 each.
