Which segment type is ideal for analysis of contact behavior over time?

The ideal segment type for analyzing contact behavior over time is a historical list. Historical lists allow marketers to segment contacts based on their historical behaviors and activities, providing a comprehensive view of how those behaviors change over time. This is essential for identifying trends, monitoring engagement levels, and assessing the effectiveness of marketing strategies over different periods.

In contrast, static lists consist of contacts that do not change after they have been created. They are based on specific criteria at a single point in time and do not automatically update, which limits their usefulness for ongoing behavioral analysis. Active lists, while dynamic and updating in real-time based on set criteria, also focus more on current behaviors rather than historical ones. Saved filters are used to create a filter view of contacts based on selected criteria but do not specifically cater to the longitudinal analysis of behavior. Therefore, historical lists provide the most relevant insights for tracking and analyzing contact behaviors over time effectively.
