Organizations may use external lists. External lists are brokered with individual list agreements that govern how long and how the use can be used.
Sometimes lists are given to the organization with all names and contact information attached. Other times, lists are used once with the organization only seeing the names of the contacts within it when the customer responds.
Lists with Names
Lists with names can be imported into the iMIS Acquisition Management tool. Campaigns and Segmentation can query this list and generate lists from it. One of the most important segmentation considerations is being able to test against different list rentals, therefore, it's important to have a testing model.
Lists without Names
Lists without names can still be tracked in Campaigns. At the source code level, assign the quantities included in the list rental. Track the list rental/purchase cost at the package level. Remember that the package gets attached to the source code. Different packages have different list costs so it's important to apply the cost to the package to properly calculate the ROI.
