Featured Testimonials

  • "We made the switch from Mailchimp to Klaviyo and haven't looked back. As a company focused on the customer experience, having a powerful email provider is crucial. Their Shopify integration is seamless and the automation abilities allow us to email our customers at the perfect moment."

    BrianChief Marketing Officer

  • "I’ve overseen two transitions from Mailchimp to Klaviyo for two different companies. The integration with Shopify is seamless and easy to set up, and there’s just no comparison when it comes to automation capabilities. The customer service is outstanding as well. Klaviyo is the clear winner."

    LeeDirector of DTC Ecommerce

  • "Integrating our Woocommerce site with Klaviyo has allowed us to build targeted prospecting, cart abandonment and loyalty email marketing flows - easily. We're seeing great performance in every flow. In fact, our email marketing was responsible for 43% of our online sales in the last 90 days. We never achieved this level of success with any other email marketing platform."
