From my understanding: 1. I would have to import my list of say 1,000 contacts into Constant contact. 2. Then export the list to open in excel. 3. Then I can filter out items in excel that are in existing lists. Lets say remove 500 items that I can see are in existing lists. 4. Then I can add the lists that the 500 new contacts are in, in excel. 5. Import the contacts back into Constant Contact? 6. Now all the contacts should exist in the proper lists? as well as the imported list group. 7. Then I can delete the imported list group? Be nice if when importing contacts it just imports the 500 new addresses as an option, and updates info from the existing 500. Then would have a new list group with just new contacts that need to be sorted. Maybe I'm missing an easier way of doing this?
