Featured Testimonials

  • "The ease of the switch from mailchimp to Klaviyo was outstanding - the Klaviyo team helped out with all my questions and hesitations. The 'out of the box'/pre built automation flow that are in Klaviyo have not only benefited us in time spent (or not in this case) in the setting up but also we have noticed an increase in our revenue. Also some flows that we would have never thought of building!"

  • “Everything is just so easy to execute. We have found that Klaviyo just works – it is robust, targeted and the UI is amazing.”

  • “We knew, longer term, we wanted to partner with a company that was constantly innovating and that would also plug in seamlessly with our ecommerce platform.”
