The automation tool that the Administrator should use to create this list is a dynamic list. A dynamic list is a list that automatically populates with prospects who match the criteria you set. You can use a dynamic list to segment your prospects based on their attributes or behaviors, such as their opportunity stage, score, or email activity. A dynamic list is constantly updated, so prospects are added or removed from the list as they meet or no longer meet the criteria. A dynamic list is ideal for creating a list of prospects who are in the prospecting stage of the opportunity, and removing them from the list once they move to another stage.
