There are two ways of building audiences in Crowdskout: a segment or a list.
A segment is a dynamic collection of profiles based on a set of criteria.
After it’s been saved, if new or different records meet the set of criteria, the segment will be automatically updated. For example, if you have a saved segment of registered voters, and more people register to vote, the newly registered voters will appear in the results of the segment.
A List is a static collection of profiles. These lists consist only of contacts you've accumulated up until the point when you create the list, and they remain unchanged unless you manually add or remove profiles within that list. For example, a list of all individuals who attended an event on XX date. This list should remain unchanged.
