The business owner requires the ability to manage inbound and outbound campaigns (offers/messages), including those from
external lists, and operational reporting for Email, SMS, Mobile Push and Site media types for Macy’s/Bloomingdales
(M/BL) using the SAS MA/MO tools. The key goal of the RTO effort is to replace separate and disparate systems by channel
with a single enterprise Omni channel Campaign, Optimization and Real Time Offer/Message solution to enable a new
platform for delivering targeted, relevant, and personalized marketing campaigns and offers/messages to customers. Support
a shift in Marketing from the traditional event/calendar-driven paradigm towards a customer-centric, relationship-driven
approach to communicate with our customers in a contextually relevant dialogue across omnichannel marketing vehicles. To
achieve the above goals Macy’s/Bloomingdales (M/BL) will utilize the SAS Campaign Management/Campaign Optimization
