A target audience for a marketing campaign is selected using a graphical user interface. A first graphical representation of a customer data attribute is dragged from a first window and dropped in a second window. A second graphical representation of a customer data attribute is dragged near the graphical representation of an initial profile that is created in the second window in response to the dropping of the first graphical representation. The second graphical representation is dropped in an action area presented when the second graphical representation is dragged near the graphical representation of the initial profile.
