A marketing team at a client has a large daily volume of promotions that have specific audience targets. Promotions are sent via their apps as push notifications to users from a pool of millions across the globe. Each is specifically tailored to a unique group of users based on age, country, state, city, and browsing and purchase behavior on their application. The client has requested a team to analyze user data to deliver approximately 20 curated audience targets daily in the form of UserID lists for them to send their promotions
