Abstract: A system and method for creating and distributing messages including dynamic content is provided. In one form, an entity provides a plurality of content segments for use in building a dynamic message. The entity also provides a listing of end users to receive a message and information associated with the user, such as demographic or prior purchasing information. In an alternate form, the service connects to the user in a communication session and collects information from the user directly. The service then uses this information, whether provided by the entity or the end user, as the basis for selection of various content segments which will make up a dynamic message for presentation to the user.
