Klaviyo Reviews in June 2026: User Ratings, Pros & Cons

A fairly experienced fan of Klaviyo

What do you like best? Intuitive, user-friendly, speedy. I also love the education/customer support surrounding it. What do you dislike? Small, buggy things; getting booted out of a shell creation before the copy is inputting, or the way bullet points render in the body of an email (with too much space). Again, small stuff. What problems are you solving with the product? What benefits have you realized? We're really learning a lot more about segmenting and personalized ...

Product Manager, CRM & ESP

What do you like best? How easy it is to automate email personalization with flows. What do you dislike? Permission settings aren't strong enough. We want our marketing specialists to be data-driven without giving them access to everything. I want them to be able to access the dashboard (aggregated campaign data), but not necessarily everything within the individual profiles. I also want to be able to use "tags" in more of the reporting & analytics features. Recommendations ...

Great platform to get you up and running

What do you like best? Super easy to use, and gives you the basics to be successful in ecommerce quickly. The built in templates and support chat are differentiating qualities that make it better than its competitors. Flows and campaigns are intuitive to use as well. What do you dislike? Some of the profile based data is harder to access, making segmentation and analysis on different types of customers different. AB Testing could be more robust, and the API seems like a black ...

Klaviyo - Email Marketing to the Max

What do you like best? I like the fact that Klaviyo lets you dynamically tag emails for better readouts on metrics for our marketing efforts. Being able to sort and filter by these metrics have saved a ton of hours and have put us ahead of schedule with our productivity. What do you dislike? MY only dislike is that I didn't really have a full scope of how Klaviyo could help companies - this is why I've had such a good time at the conference! It was great to hear other success ...

New User- Loving It

What do you like best? How easy and intuitive it is to use. I've used a bunch of other email services but this one has been the easiest to use and the quickest for me to learn. What do you dislike? The flows are a bit confusing for me. I struggle with all the double negatives that have to be used. I wish it was a little easier to make sure I had the triggers and restrictions set up properly. What problems are you solving with the product? What benefits have you realized? ...

DollarDays Review

What do you like best? My focus has been primarily product based, but I have stepped in recently to optimize our customer retention ans acquisition strategy. Klaviyo has supercharged the transition with an extremely user friendly and data driven tool. Segmentation and on line behavior have been particularly helpful. What do you dislike? Lack of reporting tools requires data exports into external BI tools. What problems are you solving with the product? What benefits have you ...

If you can't see your revenue number in ESP, switch to Klaviyo

What do you like best? Our clients weren't able to see revenue from promotions and automations from other email marketing services they were using. Klaviyo changed that. We can see what's working, what's not and what to do focus on next. What do you dislike? Not much I dislike. They have great support and any technical issues we have had, have been resolved. Recommendations to others considering the product: If metrics and visibility are important to you, make the switch ...

Klaviyo is much more than email marketing

What do you like best? The amount of data stored on customers making very powerful segments and providing awesome reporting to make more informed decisions. Being able to create variations to test is great aswell! What do you dislike? It is a little overwhelming in the beginning. Having an onboarding manager would have helped me a lot in the beginning. What problems are you solving with the product? What benefits have you realized? I’m understanding my customer a lot ...
