How do I sync abandonment data across platforms?

I've been wrestling with cart abandonment for months, and it feels like I'm watching potential revenue slip through my fingers. Every day, I see dozens of customers add products to their cart, only to disappear without purchasing. My current setup involves Shopify, Klaviyo for email marketing, and Google Analytics, but these platforms don't talk to each other seamlessly. I'm manually exporting data, trying to piece together why customers are dropping off, and it's becoming a nightmare. I know I'm losing opportunities because I can't quickly understand and respond to abandonment patterns. My ad spend is high, traffic looks good, but my conversion rate is frustratingly stagnant. I need a solution that can track these interactions in real-time, provide actionable insights, and help me re-engage potential customers before they're gone forever. The fragmentation of my current tools means I'm always a step behind, reacting instead of proactively addressing cart abandonment. I'm looking for a unified approach that can sync data across platforms, give me clear visibility into customer behavior, and ultimately help me recover those lost sales.
