Can I trigger post-purchase upsell offers to shoppers who previously abandoned?

As a Shopify store owner in the beauty and fashion space, cart abandonment has been my nemesis. I've watched potential revenue slip through my fingers countless times—shoppers who browse, add items to cart, but mysteriously vanish before completing their purchase. Traditional retargeting feels like throwing darts in the dark: expensive, generic, and often ineffective. I know these customers were interested; they just needed that final nudge. My team and I have tried email reminders, standard discount codes, and even Facebook retargeting, but nothing seems to consistently convert these 'almost customers'. The real frustration is knowing how close we are to making the sale, yet unable to bridge that final gap. Each abandoned cart represents not just lost revenue, but a missed opportunity to build a relationship with a potential loyal customer. We need a smarter, more targeted approach that doesn't feel desperate or spammy—something that creates genuine urgency and provides real value to the customer while protecting our margins.
