How do I automatically remove audience members from groups?

Our import wizard can add Salesforce records to Emma and keep them updated.  Optionally you can also add the members of an import to one or many groups. 

Another option is to Emma audience members from the selected groups who are not in the import.  You simply need to enable this option - https://b12.d.pr/BdefUG

When the import runs it will compare the Salesforce import and the members contained within to the selected group(s).  If the Salesforce import is missing records they will be removed from the selected Emma group(s)
