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

Pretty useful analytics and customer retention system.

What do you like best? The analytics of users visiting different products on our website and tracking the orders of users. What do you dislike? The segmenting features could be a bit more expanded, with wildcards for different string-values etc. What problems are you solving with the product? What benefits have you realized? We are using Klaviyo mainly for marketing and newsletter purposes.

Easy for even inexperienced users to build email, but could provide better analytics

What do you like best? WYSIWYG functionality (drag and drop), incredibly easy for marketing professionals to learn to use with little ramp-up time, option to build in UTM links throughout a campaign so I don't have to individually update all the links within an email, easy to clone/duplicate existing templates, multiple prompts to double-check your work before sending to prevent errors What do you dislike? Analytics are nowhere near as good as they could be - I have to go into each ...

Great for Price, Advanced Automation but Unreliable analytics

What do you like best? Ability to create dynamic segments and flows What do you dislike? Unreliable analytics. They never line up with Google Analytics. Klaviyo needs to work to have a more solid integration with Google Analytics. They also don't have a reliable chat support. Recommendations to others considering the product: Great for the price, but with the savings you sacrifice solid customer support and reliable analytics What problems are you solving with the ...

Blown Away

What do you like best? The simplicity of the system and its ability to track performance. The pitch was 30mins long but within about 5 mins we already knew we wanted to use this system for our email. We love the ease of using an A/B test and how easy it is to set up flows. Excellent product. What do you dislike? The only area it could work on is the design area which is a bit clunky and limited. The templates are ok but the ability to customise feels a little limited. ...

Klaviyo was a game changer for us

What do you like best? Klaviyo gave us the ability to run the email program of our dreams built around campaigns and workflows. We can tailor our message to the right group of customers. We can run A/B tests. It has enhanced our relationship with our customers and brought in extra revenues. We could not operate our business without Klaviyo. What do you dislike? It is a powerful program, but easy to learn and ramp up. We have no complaints. What problems are you solving with the ...

Klavijo for small businesses

What do you like best? I like how it's an instant plug in to our shopify and how Klavijo automatically updates with our Shopify customers info. What do you dislike? It's not as user friendly as I would like - I'm a designer and I think it could be programmed better - but that's just preference! It gets the job done. Needs more font options too. What problems are you solving with the product? What benefits have you realized? Mass emailing - we didn't have it before! And ...

Exceeds expectations

I spent 36 years building custom business software across more than a dozen industries. My "bar" is pretty high when it comes to usability. The team at Klaviyo easily meets and surpasses my expectations. The features are easy to find and operate the way you expect them to. The inside joke in the software industry is that "if you have to refer to the User Manual, it's not designed right." This team gets it. I moved from another well-known product to Klaviyo in less than one day. No support ...

Great experience and assistance

What do you like best? Though my on-boarding specialist was fantastic, the resources available via online webinars, guides, videos, and the blog were even better. I've worked with other constant contact, mailchimp, and other programs and Klaviyo was far and away better in this regard. What do you dislike? There's nothing I personally dislike, however I'd suggest you have a reasonable level of comfort with software and technology, and preferably at least a beginner level ...

Perfect software to improve and deepen the automation of e-commerce.

What do you like best? What I love about Klaviyo's ability to improve and deepen e-commerce automation, with useful and optimized features for my company. I love the integration with Shopify, this software takes information of my customer's activity in my online store and sends them advertising emails about the content that my customer has interacted in my online store, these emails are very selective intelligent when selecting destination and advertising. I also like the integration ...

Super Easy To Use and Really Intuitive!

What do you like best? Klaviyo makes it really easy to understand what's going on with my integrated Shopify store and is really useful due to all the pre-written email campaigns. What do you dislike? The only gripe I have so far is the relatively high cost when compared to the other 3 platforms I have used in the past. Recommendations to others considering the product: Just do it! What problems are you solving with the product? What benefits have you realized? ...
