What is the best description of how Braze measures a billable unit of service?

Braze measures a billable unit of service primarily by tracking specific events that indicate user engagement and activity within an application. This includes when a session starts, when it ends, any custom events that may occur, and purchases made by users. Each of these actions reflects a meaningful interaction that contributes to the overall utility of the Braze platform for customer engagement.

By focusing on these specific metrics, Braze can effectively quantify how much service is being utilized based on actual user behavior. This approach allows businesses to align their usage of the platform with the effectiveness of their user engagement strategies, as each of these interactions provides insights into user behavior and engagement levels. Thus, measuring billable units in this way supports businesses in optimizing their marketing efforts and understanding the value they get from the services offered by Braze.
