Description: Reengagement is the process of re-establishing a relationship with customers who have become inactive, seeking to reactivate their interest and encourage their return to purchasing activity. This concept is fundamental in e-commerce, where competition is fierce and customer retention becomes a priority. Companies often use personalized marketing strategies, such as targeted emails, exclusive promotions, or relevant content, to attract these consumers back. Reengagement not only focuses on recovering lost customers but also on understanding the reasons behind their inactivity, allowing brands to adjust their offerings and improve the customer experience. This process is essential for maximizing customer lifetime value (CLV) and ensuring long-term business sustainability. In a digital environment where interactions are quick and purchasing decisions are made in seconds, reengagement becomes a key tool for maintaining customer loyalty and fostering a sense of community around the brand.
