Coupon Code: What It Is, Key Features, Benefits, Use Cases, and How It Fits in Affiliate Marketing
A **Coupon Code** is a controlled, trackable discount or offer identifier that customers enter (or that is applied automatically) at checkout to receive a specific benefit—such as a percentage discount, fixed amount off, free shipping, or a gift-with-purchase. In **Direct & Retention Marketing**, a Coupon Code is more than a price reduction: it’s a lever for acquisition, reactivation, and loyalty, and a clean way to connect a message to a measurable outcome.
