What type of customer group automatically updates based on saved search criteria?

The type of customer group that automatically updates based on saved search criteria is dynamic. Dynamic groups use saved searches to pull in customers who meet specific criteria set within the search parameters. This means that whenever a new customer is added or an existing customer's details change in relation to those criteria, the dynamic group will reflect these changes in real-time.

This feature is particularly useful for businesses that want to maintain an up-to-date list of customers who meet certain behavioral or demographic criteria without the need for manual updates. For instance, if a customer meets the criteria of purchasing a specific product or reaching a certain level of engagement, they will automatically join the dynamic group, ensuring that marketing efforts and communications can be tailored effectively.

In contrast, static groups require manual updating to reflect any changes in customer status or characteristics, which can lead to outdated information if not monitored regularly. The other types, promotional and cohort, have their own specific functions and do not share the automated updating feature tied to saved searches, making dynamic the unique choice here.
