Its a large learning curve to become excellent at using, but i minor curve to get started and active. Klaviyo email flows brought in hundreds to my bottom line at a fraction of the cost for ads! I love it!

Klaviyo was a breeze to integrate with our Shopify store—just a few clicks, and we were up and running! The setup was super easy, and it instantly synced all our data. We quickly set up our email flows like abandoned carts and welcome series, which have already boosted our sales. The best part? Klaviyo pulls customer data straight from Shopify, making our emails feel super personalized. The analytics are spot on and help us tweak our strategy easily. If you’re looking to step up your email game, Klaviyo is a no-brainer. Highly recommend!​⬤

I hate the Klaviyo app. I was forced to switch over to it when I hired an email marketing team last year and I wish I never left Omnisend. Klaviyo requires you to be an expert on their platform in order to be able to use it. I've been trying to modify a basic ORDER CONFIRMATION email, I just need it to show the variants of the products ordered, the prices, shipping, tax and total.. but it's so difficult to do!!! It shouldn't be so difficult to make a basic order confirmation email show the items ordered and the total paid... I will be leaving Klaviyo as soon as I can figure out how to migrate all my existing flows to a better platform.

I subscribed paid plan on last Sunday for $100. I requested for a refund as I realized their UI isn't intuitive and they charge way more than other companies and I have not used for a single day. They just send me an email with their policy saying that they will NOT refund the money even after I explained to their support and the time of contact was within 5 mins of subscription. So tell me anyone who do not agree that this is their tactics that they want to suck all the money they can from new eCommerce store owners like me. Their support is poor and their product isn't as high performing like other people saids, and that's why they have no refund policy. If you are new to eCom business owners, I strongly advise you to stay away from Klaviyo, who does not give a dame about their customers or potential customers. They don't give money back for any reason, even if you have rigimate reason and contact you right away. Please don't get the idea of where people use for half of month and asking for a refund. I requested a refund 5 minutes after I realized their plan wouldn't work for my business. Be aware of this company who will suck your money out of you every chance they get. I would highly recommend Omnisend over Klaviyo and I would stop people from using Klaviyo. Amazed by their lack of professionalism and their policy who doesn't give a damn about people. 0 Star for this institute.

I love that the app is easy to use for beginners and how it's versatile. However, it took me a long time for me to finally get help from the support for the error that kept happening on my free plan. I couldn't get through the sales (phone and email) and support service because my free 60-day support access had ended. Although I had installed it more than 60 days prior, I only started using the actual app from 2 weeks ago. Ended up speaking with Shopify support to have them contact me.

There billing is deplorable. You can't make changes to your account without being double billed. They don't do proration and then if you wait to change your plan at the end of your billing so you don't get double charged they will still charge you for the highest plan and tell you that they can't help you and you aren't owed a refund of the difference.

I call that theft. I downgraded to a $100 plan and entered my info to pay for that plan. Instead of it charging me for the new $100 plan I was charged $205. I reached out immediately to get the difference refunded. I was told that I paid the bill before I made the change which was 100% false because I updated the payment information after I made the plan change.
