# User Segmentation CrossEngage enables you to create user segments, based on User Traits or User Behavior. This allows you, not only to better understand your User Base, but also to tailor your communications for specific User Groups, across a number of channels. Note that Segments are re-calculated every time they are used. This ensures that you always see the most up-to-date information on your segments, and ensures that new Users, added after a Segment was created, will be automatically added to a segment under use, if they fit the Criteria for it. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://documentation.crossengage.io/data-and-engagement-platform/user-segmentation.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
