A marketing team is designing a personalized email campaign for a retail client who sells outdoor gear. They want to utilize dynamic content to enhance engagement based on customer preferences and past purchase behavior. The team segments their audience into three categories: frequent buyers, occasional buyers, and new customers. They plan to include different product recommendations in the email based on these segments. If the team decides to show 5 product recommendations to frequent buyers, 3 to occasional buyers, and 2 to new customers, what is the total number of product recommendations displayed across all segments in one email campaign?
