From the Marketing segmentation home pages, you can perform the following tasks:

• Create a segment. A segment defines a target set of customers or prospects. In most cases, the members of a segment change over time because the criteria is reevaluated against the most current data in your database.
• Create a segment tree. Use a segment tree to select one or more segments and split the segment members into smaller groups (or target cells).
• Create a List format. List Formats define the layout of files that you can use for purposes such as mailing to postal addresses or email addresses.
• Manage marketing jobs. The Manage Marketing Jobs link on the Marketing segmentation home pages displays your jobs and cache entries. The administrator can display job and cache entries for each user. For more information about managing marketing jobs, see Managing Marketing Jobs.
