Hungry for loyalty research? Well, pull up a chair, my friend, and tuck into this deep-thinking study from SAP Emarsys. They define five kinds of loyalty and report how they’ve changed over time. Then they dig into loyalty drivers, attitudes, behaviors, and expectations across the US, UK, Australia, and Germany. You’ll probably be happy to know that 24% of respondents are more loyal to brands that offer more personalized marketing if it’s tailored to their needs.
