Generating smaller lists from an existing segment or list is an important step in creating campaign test strategies. The subsets created are useful for creating test lists, control groups, and/or exclusions.
It is possible to perform a random split of any segment (minimum of 2) or list (up to 10) in a single operation. The split can be based on counts or percentages and follows an automated naming for ease of use.

This article focuses on generating a list from an existing segment.

Note: Splitting a segment generates one List (a full snapshot) of the segment. When splitting a list, a minimum of 2 Lists are needed and these lists remain static.
