How do I measure the lifetime value of recovered cart abandoners?

As a Shopify store owner, cart abandonment has been my constant nemesis. I'm spending thousands on ads, driving traffic that looks promising, but then watching potential customers slip away at the last moment. It's not just frustrating—it's costing me serious revenue. I know these aren't just random browsers; these are people who showed genuine interest by adding products to their cart. But here's my real challenge: even when I manage to win some of them back through discounts or retargeting, how do I truly understand their long-term value? Are these recovered customers just one-time deals, or do they become loyal, repeat purchasers? I need a systematic way to track not just the immediate conversion, but their entire journey with my brand. I want to know if the effort and potentially slim margins on recovery offers are actually worth it in the grand scheme of things. My gut tells me there's gold in understanding these customers, but I need data, not just intuition. I'm looking for a method that goes beyond simple conversion tracking and gives me a comprehensive view of these 'recovered' customers' lifetime potential.
