Klaviyo helps me to get more customers and get more revenue from abandoned checkouts. It also allows me to reach my customers more easily and with a more professional look! Love the app!

Klaviyo is the perfect solution for Shopify websites that need to take direct marketing and customer experience to the next level. Great support to walk you through any issues. I've used 3 other solutions in the past, and I highly recommend Klaviyo.

Great app! My only complaint is the interface is looking a tad dated and jenky now. Full of wonderful functionality, though! The best app for emails and we are very happy! ^_^ X

SUPER SIMPLE. NO COMPLAINTS. I would however like to know how to have email subscribers from privy automatically added into my Klayvio list as opposed to having to manually add.

Great marketing automation tool. Have set up all kinds of automations for our Canadian customers whom we want to segment from our US customers. Would rate 6 stars if I can.
