Segments can also be used as input cells to another Segment process. For example, assume that you want to segment your customers into six age ranges. Your database contains a field called AgeRange that assigns one of six age ranges to each customer. Segment by the AgeRange field to create the six segments.

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.
