Featured Testimonials

  • "Our company's #1 revenue channel is email and Klaviyo plays no small role in this. The automation, segmentation, and integration with Shopify are all best in class. We've cut our weekly time spent in half and doubled our revenue since moving to the Klaviyo platform."

  • "We went from crawling to sprinting. There are just massive operational and marketing benefits we get out of Klaviyo. It’s making the pie bigger."

  • "We look at the lifetime value of our customers, and we notice when people buy and make repeat purchases. If they’ve bought from Beyond Yoga before, they’re going to come back during this time because they know our products, they know the quality, they want to buy it for their friends, or they want to give it as a gift. They come back at a high frequency, so making sure they’re getting those personalized messages right is really important to us.”
