Hi,
It is currenty not possible to export users including this information. What you can do is to export your subscribers per list and then filtring everything in Excel.
If you have the Enterprise version you have some extra options. Segmenting your lists enables you to send email to subscribers that are subscribes to List A and not to List B for example. You can use segments as a one time selection in the send settings of your campaign, or you can save the segment so it will be applied dynamicly whenenver you select the segment. Furthermore segments offer you extra features using atuomations. For example you can easily sunscribe users that are subscribed to list A and not subscribed to List B to List C.
