You can create segments to select a group of contacts, for example, if you want to create an interaction involving several contacts, such as direct mail.
In the General section, in the No. field, enter a number for the segment.
Alternatively, if you have set up number series for segments in the Marketing Setup window, you can press Enter to select the next available segment number.
You can now add contacts to the segment. For more information, see How to: Add Contacts to Segments.
