Thank you for your reply. While segments and tags are great they do not help me to clean up my extensive lists. I do not want to delete or consolidate my existing lists but would much prefer to have a folder tree option so that I could expand or collapse the lists should I choose. It would be great to select an overarching category when selecting lists or have the option to select only some of the sub lists should I prefer. Thank you for your consideration.  ... View more

Hello,   I am a long term member of constant contact and have a lot of historical data for ever changing client list. It would be extremely helpful if the the ability to have sub email lists existed.

Happy to talk someone through the idea if you are interested. Thank you for the consideration.    ... View more
