So many things guys. Drip is almost like an enterprise version of Klaviyo. Workflow creation is much more robust in my experience. New features get rolled out really fast and their general shopify integration is solid. They're rebuilding their native woocommerce integration too. The combinations of rules, workflows allows you to do crazy things. With Klaviyo, sure you can do a bit of dynamic cart stuff, which is sufficient for most basic ecom usage. Klaviyo is great, don't get me wrong. But I always pick Drip over Klaviyo.
