You could then use these six segments as input to another Segment process that further divides customers by another field or query. For example, assume that your database contains a field called PreferredChannel, which specifies each customer's preferred contact channel — direct mail, telemarketing, fax, or email. Using the six age range segments as input, you could then create a second Segment process to segment by the
PreferredChannel field. Each of the six age range segments is further segmented into four preferred channel segments, to produce a total of 24 output segments.
