Should I call high-value cart abandoners?

I've been running a Shopify store selling premium fitness equipment, and lately, I'm noticing something that's driving me crazy. We have these high-ticket items—think $500-$1000 exercise machines—where customers are adding them to their cart but not completing the purchase. These aren't just random browsers; these are high-intent customers who've spent significant time exploring the product, reading specs, and nearly committing. Every abandoned cart feels like money literally walking away. Our margins are tight, and each lost sale represents not just revenue, but significant marketing spend wasted. I'm wondering if a direct, personalized approach like calling these potential customers might actually recover these almost-sales. But I'm also hesitant—I don't want to come across as pushy or desperate. There's a fine line between helpful follow-up and annoying sales pressure. Plus, our team is small, and manually calling every abandoned cart seems time-consuming. I need a scalable, strategic approach that doesn't require constant manual intervention but still feels personal and increases our chances of converting these high-value potential customers.
