Absolutely top notch customer service. Above and beyond, friendly and polite, across the board. Ta very much


This app is well marketed, and go to tool for e-commerce email marketing. However be cautious that installing klaviyo shopify app and inserting their .JS to your store it takes 15 website speed points out of 100 possible speed points. Our developer pointed this out that klaviyo app inserts a ton of not needed stuff to the site that kills the speed performance score of the site. WE ran a test where we removed their .JS from our store and our google speed insights score went from 20 to 35... Klaviyo please fix this

I have just started using this app and loving it so far. I installed this app to help me with the email portion of my business. I have been using basic Shopify email and wanted a more professional look. It took me a little bit to put it all together, but pleased so far. I am only using the email and pop up features right now with no problems. I am loving the automations in the welcome email section, and the many email templates to choose from. I may dive into more later on.

Very undependable app. SMS isn't sending 80% of the time. I tested with our own 2 numbers but the flows and automation don't work! Worst experience ever

Knives Et Cetera

I would never use Shopify without it. Once you get in the right way of thinking and using Klaviyo, there's no going back.

So easy to use, even for people like me who aren't the most savvy. The help center is pretty robust too. Love it!


Creating email flows is super easy with Klaviyo. By far, this is the best tool I've used in my Shopify store.

I just started using this again, thank you. This is a great platform. You have a lot of great options and templates to choose from.


Exactly what I needed! So much easier than other apps I've tried! It's perfect! The flows and campaigns have become easier. It took me a few hours to figure out everything, now it's just falling into place. My Shopify developer recommended it and i'm glad he did!

I needed this 5 years ago! This app is going to save my email marketing strategy (or lack thereof). So easy to use and so many automations to take advantage of. I am in automation heaven!
