Klaviyo: Email Marketing & SMS

We use Klaviyo for marketing to our online AND in-store customers. The integration is fantastic, it can pull in all the items from an abandoned cart with links back to the cart or the specific items. You can feature collections in your emails automatically, segment your customers based on their purchase (or even browsing) history. If you want to speak directly to the people who are shopping on your site, this is the way to do it.
