I am Klaviyo's biggest fan! When I started with them in 2019, I had zero contacts. We now have over 1 million emails collected with outstanding segmentation. Our open rates began around 8% and now have soared to nearly 30%. Klaviyo drives 20% of our business's revenue. Further, their customer service is unlike anything I have ever experienced. I've had the same rep since day 1 (Katelyn!) and she knows our business inside and out - every emaill, every flow, and she is always available to help. Having both SMS and email under one house has also been a game changer for us. A++

It is extremely powerful and useful. I suppose, by definition, that means it has to be complicated. And it is that. Especially for a newby like me. But with dogged determination comes success and satisfaction.

I've had this app about 1 week and I love it. I was using another mailing system for 3 years and it was difficult to use. After I spent a few hours learning Klaviyo, I am really happy with the results of my email campaigns and flows. I think this is the motherboard of all mailer apps. There's so much to learn, but if you spend the time to learn it, you should be ready to go. I can't believe I spent 3 years with a different mailing system! My old one was so hard to set up segments, lists and flows, but Klaviyo makes it super easy and customizable. Email marketing is such an important part of how we make money, so I was ready to invest in something more worthwhile. Give it a try! I tinkered with it for a week before I used the paid version.

Klaviyo is an excellent tool, and is structured in a way that makes the most of customer data. It's fully integrated with Shopify. The flows that come out of the box are valuable ways to attract new customers and automate marketing/customer support. You can segment and focus different campaigns on VIP customers. Their success and support teams are great.

We are converts from Mailchimp and won't look back.
