It’s simple. We’ve used a lot of email software and nothing comes close to the functionality and ease of use of Klaviyo. You can find enterprise software with more functionality, but these are much more expensive and much harder to use, or you can find comparably easy-to-use software, but these come with none of the functionality of Klaviyo. What’s more, Klaviyo is specifically made for e-commerce companies, so it integrates very well with all e-commerce platforms (Shopify, Woocommerce, Bigcommerce, Magento etc.).
