Use Cases and Deployment Scope
I used Unica to deliver marketing campaigns for multiple clients. I found Unica very useful for preparing data segmentation for marketing campaigns, and it provides a rich, easy-to-use, and easy-to-understand interface; the Unica flowcharts are very simple. I have used Unica Campaign, Deliver, and Interact and found them to be a complete package for any organization.
