Great customer service is vital in retail industries, increasing brand loyalty and revenue while poor customer service turns customers away. To improve customer service, businesses should unify customer data using customer data platforms (CDPs) to create complete profiles of customers' preferences and behaviors. Protecting customer data with secure authentication methods and giving customers control over what data is stored and used is also crucial. Investing in digital channels, like live chat, SMS, and social media, drives revenue and helps businesses meet changing customer needs. Predicting customers' needs using the right tools can lead to proactive customer service, while leveling up self-service options can reduce the number of customers reaching out via live chat. Finally, celebrating customers and showing appreciation for their loyalty can improve retention rates.
