How do I prevent coupon sharing from recovery emails?

As a Shopify store owner, I've been battling a persistent problem that's eating into my margins: coupon code sharing. Every time I send a recovery email with a discount to an abandoned cart, I'm seeing that code get passed around on discount sharing websites, forums, and group chats. What started as a targeted strategy to recover lost sales is now becoming a revenue leak. My carefully crafted single-use codes aren't truly single-use, and customers who weren't even in my original abandoned cart are using these discounts. This isn't just about losing a few percentage points—it's about maintaining the integrity of my pricing strategy and protecting the perceived value of my products. I need a solution that creates genuine, personalized urgency without making my discounts a public commodity. The traditional approach of generic recovery emails with static codes is clearly broken, and I'm looking for a smarter, more sophisticated way to re-engage potential customers without compromising my brand's pricing strategy.
