This document discusses loyalty marketing, including its objectives, scope, process, and case studies of successes and failures. Loyalty marketing focuses on growing and retaining existing customers through strategic relationship building. It aims to better understand high-value customers and provide them targeted benefits to increase their lifetime spending and profitability. Case studies show that successful loyalty programs like AirMiles clearly communicate benefits to attract and reward loyal customers, while failures occur when programs have no communication, low redemption rates, or unsustainable costs.
