# Campaigns: Promotions and Discounts

Commerce Engine campaigns offer promotions that target diverse audience types, helping you attract new customers, reward existing customers, and enhance retention of long-term customers. Commerce Engine campaigns are discounts, such as special offers or limited-time pricing, you can apply to new or existing products, billing plans, and subscriptions. The discounts provided by a campaign can be currency-based or percentage-based, and applied to one-time purchases or applied to a recurring subscription for a specific period. You can offer a limited-time discount or one that spans multiple subscription billing cycles.

Commerce Engine provides promotion campaigns, which allow you to generate a single campaign code that can be distributed to multiple customers. A promotion code is not unique to individual users and is typically publicly available through mass distribution. Creating and launching a Commerce Engine campaign is fast and simple within the Commerce Engine Portal or via the Commerce Engine API. Commerce Engine enables marketing teams to build and run campaigns with little or no assistance from IT.
