BIRDY GREY review for Klaviyo: Email Marketing & SMS

Having used Klaviyo with Shopify Plus storefronts starting in 2019, I can certainly speak to both Klaviyo's current functionality and their track record of always improving. There are a few circumstances in which advanced functionality requested of me wasn't available through Klaviyo, but on the whole when working with Shopify as the storefront Klaviyo is almost more like a built-in solution than an add-on app with how tight & aligned the integration is. Advanced, store-specific asks have been possible through their developer documentation and in-house custom builds, and we're also very grateful to have a responsive, helpful CSM who advocates for our business needs when we want to innovate within the channel. No technology is perfect, but I've been able to see Klaviyo constantly improve which speaks to the tool's strength in build, support and commitment to its customers.
