With the latest relase of cij we where blessed with the feature, that we are now able to import CSV Lists containing emailaddresses to build a static segment group.

I know it is preview, but It would be very nice to use any defined Alternate Key defined for the contact table to import those contacts to the segment. Many of my clients does not have unique emailaddresses ( thanks to B2B businesses). They then would love to use Contactnumber/Customernumbers or external Ids columns to identify a contact. Would really love to see that!
