I have two things that would be very helpful for contact management. The first is dealing with contacts: it would be handy to be able to archive past lists. We have several lists that we don't access often, yet we have to scroll through them every time. It would be nice to be able to put them in a file that we can access when needed, but not have on our main list of contact lists.
Another VERY helpful feature would be to be able to take the lists we have, and gather several of those lists into one file. For instance; we have a weekly email newsletter that goes out to about 7 different lists (sponsors, members, specific clubs, etc). But, there are other emails that may use 4 of those lists. So, to be able to take those lists and create a "weekly blast" list that contains the lists we would normally have to choose one by one. Then, say, Business Alliance may use some of the same lists, but combined into one click. So the lists would continue to be available singly or put into multiple other files to create groups. This would be very helpful in an organization such as ours that may have a few people, including interns that come and go, working on the emails. They now have to remember what lists get what emails.
