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

Money making machine- but kinda slow

What do you like best? Klaviyo takes making money and growing companies seriously. It's a little bit slow to load, but ultimately it works and is super easy to integrate and setup a foundation.

It's a bit slow, and there's a lot of analytics I don't know what to do with. What problems are you solving with the product? What benefits have you ...

What do you like best? The flow feature is what I like best in Klaviyo.

We also think the segmentation is a great feature that allows us to target specific groups of customers in accordance to what we're sending out. What do you dislike? At first, the Klaviyo interface seemed a little confusing. Now that we are use to it, it is fine, but I feel the ...

Thoughtful, covers email marketing basics, excited to see improvements

What do you like best? Simple interface and it's easy to get started. There's a lot of pre-built options to help new customers and novice email marketers get started. What do you dislike? Segmentation feels a little slow. There are some nice-to-haves missing: quickly copying elements of segmentation, viewing outputs, checking counts. Would also be nice to have workflows that show you how many people are waiting in each step without clicking into them (at a high level). I also wish ...

User friendly and effective. I get excited about what I can accomplish using Klaviyo.

What do you like best? The flow creator makes it easy to see and communicate automations What do you dislike? That I cannot preview mobile the same way as desktop. It would be best to see both the desktop and mobile at the same time or be prompted to see mobile. In a mobile first world, I constantly forget to double check the layout and that sucks. What problems are you solving with the product? What benefits have you realized? We are solving complex departure and ...

Director, General Store

What do you like best? The ability to tie revenue to my email campaigns is the absolute number one reason I choose Klaviyo.

I'd like the ability to edit the code in when using the rich text ...
