Which of the following is an example of standard attributes collected by Braze?

User ID is a standard attribute collected by Braze because it serves as a unique identifier for each user within the system. This attribute enables Braze to track user behavior, interactions, and engagement across various channels and campaigns. By using the User ID, businesses can effectively manage user profiles, tailor communications, and analyze user data to improve marketing strategies.

While user purchase history, last clicked campaign, and user unique device ID are also valuable pieces of information, they are considered more specific or contextual data rather than standard attributes. User purchase history is typically an event or behavior recorded within the system, while last clicked campaign focuses on a specific action taken by the user, and unique device ID pertains to the specific device being used. These attributes may be important for detailed user segmentation and personalized messaging, but they do not serve as fundamental identifiers like User ID does.
