How do I train support staff on abandonment issues?

As a Shopify store owner, I've been wrestling with a persistent challenge: cart abandonment. My team is fantastic, but they're often left scrambling when customers drop off during the purchasing journey. I've noticed our support staff sometimes struggle to understand why customers aren't completing purchases, and more importantly, how to re-engage them effectively. We're seeing decent traffic, but our conversion rates are frustratingly inconsistent. Each abandoned cart feels like money slipping through our fingers. I need a systematic approach to train my team to not just react to abandonment, but proactively understand and address the underlying issues. Our current process is reactive—we get a notification, then try to reach out. But I want a more strategic method that helps our support team recognize patterns, understand customer hesitation, and have precise tools to recover potentially lost sales.
