To ensure that customers do not receive more than four promotional emails per quarter, you can use customer contact limits. This setting allows you to define the maximum number of contacts a customer can receive over a specific period, regardless of their responses to previous actions. By setting this limit, you can prevent overcommunication and enhance customer experience.

Introduction to Group By and Filter Components:
* The Group By component groups data based on specified properties, allowing aggregation of data points.
* The Filter component is used to include or exclude actions based on specific criteria.
Dotted Line Relationship:
* In Pega's visual strategy canvas, a dotted line between two components indicates a reference relationship rather than a direct data flow.
* When a dotted line connects a Group By component to a Filter component, it signifies that the Filter component is using a property defined or aggregated in the Group By component.
Functionality Explanation:
* For example, if the Group By component aggregates customer data by region, the Filter component can then use this aggregated data to filter actions for specific regions.
* This relationship ensures that the filtering process considers the aggregated data, making the decision strategy more dynamic and contextually aware.
Verification from Pega Documentation:
* As outlined in Pega's documentation, a dotted line signifies that the Filter component references a property from the Group By component, enabling more complex and accurate decision-making processes.
