What's the best way to recover mobile cart abandoners?

Every month, I watch hundreds of potential customers slip through my fingers. They browse my Shopify store on mobile, add products to their cart, and then... nothing. Just abandoned carts and lost revenue. I'm running Meta ads that drive decent traffic, but my mobile conversion rate is frustratingly low—around 1.2%. These aren't just missed sales; they're wasted ad spend. Each abandoned cart represents money I've already spent acquiring that customer, only to see them walk away at the last moment. I've tried generic pop-ups, but they feel spammy and interrupt the user experience. I know mobile shoppers are different—they're often browsing quickly, getting distracted, or hesitating about their purchase. I need a sophisticated solution that understands mobile shopping behavior, creates genuine urgency, and feels native to my brand. It can't just be another annoying interrupt; it needs to be a smart, personalized intervention that makes the customer feel understood, not pressured.
