What personalization options are available for my email templates?

As a Shopify store owner, I've been struggling to make my email communications feel more personal and targeted. My current email templates feel generic and bland, and I know this is hurting my engagement rates. I've noticed that when I send the same template to every customer, open rates are low, and click-throughs are even worse. I want to create emails that feel like they're speaking directly to each customer's unique journey and purchase history. It's not just about looking professional—it's about creating a connection that turns one-time buyers into loyal customers. I need a solution that can help me segment my audience, dynamically insert personalized content, and make each email feel like it was crafted specifically for that individual customer.
