What kind of messaging works best in a cart abandonment pop-up? Should it be helpful create urgency or offer a discount?

I've been wrestling with cart abandonment for months, and it's driving me crazy. My Shopify store gets decent traffic—around 5,000 visitors monthly—but our conversion rate hovers around a frustrating 2%. I watch visitors browse products, add items to their cart, and then... nothing. They just disappear. Every abandoned cart feels like money literally walking away. I've tried generic pop-ups with basic 'Wait!' messaging, but they feel spammy and ineffective. Some colleagues recommend discounts, but I'm terrified of training customers to always expect a deal. I need a strategy that feels genuine, creates real urgency, and doesn't make me look desperate. The challenge isn't just about recovering lost sales—it's about understanding why customers are leaving and creating a messaging approach that feels helpful and compelling. I want something sophisticated that respects my brand's integrity while gently nudging hesitant shoppers toward completing their purchase. It can't feel manipulative; it needs to feel like I'm providing a valuable service or solving a potential concern they might have.
