A Filtered Data Extension is the best choice when a marketing associate needs to create a criteria-based subset of an audience from another data extension without using SQL. This type of data extension allows users to apply specific criteria to an existing data extension to segment the audience based on attributes or behaviors without the need for writing SQL queries. This is particularly useful for marketers who may not have SQL skills but still need to perform targeted segmentation. Salesforce Marketing Cloud provides a user-friendly interface for setting up these filters, making it an efficient way to tailor communications to specific audience segments.
