Campaign Master is totally web based - nothing is needed on your PC except Internet Explorer. The IT department will love it - it has nothing to do with them at all.
It means that that setup is instantaneous. Open your browser and enter the URL for your account, or select it from your Favourites list.
It also means you can manage your campaigns, recipient list, database, everything from anywhere that has Internet access. The office, home, the airport lounge, a friend's place, and Internet cafe. Anywhere.
