Segments are a different part of your list that you have specially created. Segments are generated based on information of your contacts such as, State, Business Name, or even something custom, like a special tracking code for a group of people. By creating a Segment, you’ll be able to email to these people, separately from the rest of your list, or even exclude them from an email. To create a segment:
The more information you have of your clients, the more thorough your segment will be. Also as a tip, you can create codes for certain contacts in a list (this could be product codes or tracking codes). You can then later use those codes to segment them in Benchmark. If you don’t have much information of your contacts, utilizing Surveys and Polls can be one way of collecting this information.
