How often should I test new recovery strategies?

As a Shopify store owner who's constantly battling cart abandonment, I've become obsessed with finding the right recovery strategies. Every lost sale feels like money literally walking out the digital door. I've tried generic discount popups, email follow-ups, and even SMS reminders, but nothing seems consistently effective. My traffic is solid—thanks to some killer Meta ads—but my conversion rate hovers around a frustrating 2-3%. I know there's potential being left on the table. Some days, I see 50-100 abandoned carts, and each one represents not just lost revenue, but wasted ad spend. I'm not looking to bombard customers with generic offers, but I need a smarter approach. How frequently should I be testing and iterating on these recovery tactics? Is there a systematic way to understand what truly motivates hesitant shoppers to complete their purchase? I want a strategy that's data-driven, respects my brand's integrity, and doesn't make me look desperate. My gut tells me there's a more sophisticated way to convert these almost-customers, but I'm tired of shooting in the dark with random tactics that promise the moon but deliver pennies.
