In my Vertical Response account, I maintain a "Master List" - I can then "tag" users to be part of sub lists. That way, I can mail everyone, or just "Sub1" list, "Sub2" list, etc.
I imagine Exchange has something to replicate this setup - can it be done within public folders? distribution lists? sharepoint?
My first thought was to make a "Master" distribution list and then use categories to sort through that list - but I don't know that there's anyway to quickly mail a subsection of categories.
Or if I make a public folder of contacts, and then subfolders ("categories") - can I email the "Main" folder to go to everyone - and then pick a subfolder to only send to that grouping?
Any other thoughts?
