How do segments work?

Segments are based upon custom fields contained in your Emma subscriber lists.  So the first step to building a segment is to create one or more custom fields (depending on how much you want to segment upon).

Both our import wizard or field mappings features allow you to quickly and easily create Emma custom fields and map them to Salesforce fields. When you save field mappings or schedule an import via the wizard custom fields will be created in Emma and they will be mapped to Salesforce. Once the fields have been added to your Emma subscriber list you can build your segments. To do this either login to Emma directly or click on the Emma tab in Salesforce. Then follow this guide from our friend at Emma
