Which detail ensures that contacts successfully enter a Journey based on existing limitations?

A successful contact entry into a Journey relies heavily on the data model and its relationship with the root contact. Ensuring that the data extension has a direct relationship to the root contact is critical because it establishes the link between the contact records and the Journey logic. This relationship allows the Journey to effectively identify and target the right contacts based on the criteria defined within the Journey.

The direct relationship means that the Journey can accurately utilize the attributes of the root contacts to personalize the experience and make data-driven decisions throughout the Journey process. Without this direct linkage, the Journey may not be able to pull in the necessary contact information or execute actions based on the defined logic, leading to potential gaps in participation and engagement.

While refreshing data, having a sufficient data count, or exporting data could contribute to effective Journey execution, they don't directly ensure that contacts have the necessary linkage to be processed correctly within the Journey framework. Thus, the focus on maintaining a clear relationship with the root contact is paramount for a successful Journey entry.
