Segments are used to isolate business units that have unique needs or otherwise need to be managed independently. There are two types of segments: Standard and Informational. A standard segment contains mailboxes, topics, and other elements of a fully functional customer interaction system. Informational segment (i.e., not a Standard Segment) do not contain mailboxes or topics and as a result cannot receive or send email. Informational segments are used to store contact or interaction properties, or to provide structure to your overall iService configuration.
Additional information on the various configuration options for Segments can be found in the section entitled, “Segment Configuration” later in this document.
