A Data Graph is the correct source because it combines a primary Data Model Object with related objects into a structure optimized for personalization. For Marketing Cloud Next profile personalization, Salesforce typically configures the Data Graph with Unified Individual as the primary DMO , then adds related objects such as Individual, Contact Point Email, purchases, service records, loyalty data, or other associated profile information.

This differs from using the Unified Individual DMO alone. The Unified Individual provider can expose attributes directly stored on that object, but it doesn't provide the same ability to traverse and expose attributes from multiple related DMOs. The requirement specifically states that the content block needs data from related objects , making the Data Graph necessary.

A Personalization Recommender is designed to generate individualized recommendations rather than simply expose relational customer attributes for ordinary email personalization.

Salesforce explicitly states that Data Graphs used for Marketing Cloud Next personalization are typically based on Unified Individual and can include related data such as purchases or service cases. The uploaded bank also keys A.
