What type of list is suitable for an engagement program that adds and removes prospects based on scoring?

A dynamic list is the appropriate choice for an engagement program that adjusts based on prospect scoring. This type of list automatically updates to include or exclude prospects depending on real-time changes in their scores or attributes. As prospects interact with your content or engage with your brand, their scores can increase or decrease. A dynamic list's ability to reflect these real-time changes ensures that only the most relevant prospects are targeted in your engagement program.

Segmentation rules are generally used to create static groups based on predefined criteria and do not automatically update. Automation rules are typically used to automate specific actions rather than manage lists of prospects directly. Completion actions are specific responses triggered by a user’s action within a form or engagement but do not manage lists of prospects in the way a dynamic list does. Therefore, the dynamic list's inherent capability to adapt makes it the optimal choice for a program focused on fluctuating scores.
