Campaigns and promotions overview
A campaign pertains to information that intends to promote sales and market consumption among customers. Campaigns are time bound and always focus on specific user segments as the target audience. They serve as the mechanism to draw customers' attention to certain items, but they do not have any impact on user transactions, such as ordering.
A promotion, on the other hand, pertains to the set of rules controlling the items, targeted customers, and takeaways within a campaign. Unlike campaigns, promotions impact user transactions.
Campaigns and promotions go hand in hand in e-Commerce and are dependent on each other. A campaign needs rules found in a promotion to define offerings such as pricing discounts and item giveaways that promote sales, while a promotion must be tied together with a campaign to provide information and context to its defined rules.
