When should you use the list model for subscriber data?

Using the list model for subscriber data is particularly beneficial when simplicity is prioritized over performance. This model is user-friendly, making it easier to manage and organize subscriber data without the complexities that can come with more advanced data structures, such as data extensions. For marketers who may not require the sophisticated capabilities of data extensions, the list model serves as an uncomplicated means to segment and target subscribers effectively.

While lists can handle smaller volumes of data efficiently, they may not be as performant as data extensions for larger datasets or more intricate data relationships. Therefore, opting for the list model is generally ideal when the primary aim is straightforward management rather than extensive performance optimization.

The other contexts—sending global messages, having a subscriber list exceeding 500,000, or triggering sends—are better suited for using data extensions, which are designed to handle larger, more complex datasets with greater flexibility and performance efficiencies.
