Klaviyo helps eCommerce businesses sell more by using their data to power super-targeted, highly relevant email and advertising campaigns. Unlike other email or marketing automation solutions, we're really good at getting data out of your ecommerce platform - whether it's Shopify, Magento, a customer implementation, or something else. We let you combine that data with website behavior and information from other marketing tools, then use it to target, personalize, analyze, and optimize your marketing. And the best part is, we make it easy. Not 'six-months-of-development' easy or 'only-if-you-want-to-do-the-basics' easy. Just easy. Thousands of ecommerce stores like Kohler, Chubbies, Nomad, and Huckberry grow their revenue using Klaviyo. Learn how they're doing it at klaviyo.com.
