Vodafone's e-marketing strategy aims to integrate web, email, and mobile channels to enhance the customer experience. A key challenge is linking customer activity across devices using cookies. Vodafone sends reminder emails to customers who added items to their online shopping basket but did not complete the purchase. These emails contain links to return customers to their abandoned baskets. However, if customers browse the website on a laptop but access the reminder email on a smartphone, the basket cannot be recreated due to lack of cookies on the mobile device. Vodafone's strategy is to develop a comprehensive, mobile-optimized customer experience while measuring the impact of mobile marketing to improve future campaign effectiveness and efficiency.
