Which of the following filters can you include an "Add Constraint"?

1. Number of Employees

2. Industry

3. Filled out form

4. Member of Smart List

The correct answer is: Filled out form

The option related to "Filled out form" is correct because it allows the user to specify conditions that provide added granularity to the Smart List query. Adding a constraint in this context means you can refine the results by including more specific criteria—like which form was filled out, or what date it was completed—offering more targeted audience segmentation. This is particularly useful in marketing automation, where understanding specific user interactions is key to tailoring follow-up marketing efforts. Other options do not support adding constraints in the same way. For instance, the number of employees and industry are typically broader categories that define segments without the ability to layer additional criteria in the same manner. Also, "Member of Smart List" refers to a predefined group, which doesn't lend itself to being constrained further as it simply targets individuals already identified by other criteria set in the Smart List.
