A major drawback of Klaviyo is its costly pricing model.

As your contact list grows, the price increases significantly, which can become a concern for users managing larger lists. Review collected by and hosted on G2.com.

Klaviyo is straightforward for day-to-day email work. The template builder is clean, and it doesn’t take long to set up simple campaigns or pop-ups. Ease of implementation was surprisingly smooth — I had forms and basic flows running pretty quickly. I also appreciate that most features work out of the box without extra integrations. For a small team, it’s the right balance of functionality and simplicity. Review collected by and hosted on G2.com.

Some areas of the UI feel a bit cluttered, especially when managing segments or lists. Certain items have to be removed one by one (similar to profiles), which slows down cleanup. Support is mainly email-based and handled through their virtual assistant — there’s no real live chat, so responses can feel delayed when you need quick help. Not deal-breaking, but it’s an area that could be better. Review collected by and hosted on G2.com.

I like Klaviyo for how tightly it connects customer behavior to action. It lets me quickly turn real-time data into lifecycle flows that drive repeat purchases and long-term LTV. It removes the gap between insight and execution, because everything is connected, like data, segmentation, flows, and reporting. I can measure impact clearly and iterate fast. Previous teams I've worked with switched to Klaviyo from more limited email platforms because it offered stronger insights and actionable options. It made it easier to act on customer behavior and tie email/SMS directly to retention, LTV, and revenue growth. The initial setup was fairly straightforward, especially with Shopify, as core integrations, data syncing, and basic flows were quick to get live. Review collected by and hosted on G2.com.

One area for improvement is deeper native retention reporting, especially around cohort analysis, LTV forecasting and attribution across flows and campaigns. While Klaviyo is strong operationally, I still rely on external tools or exports for more advanced lifecycle insights. I'd love to see more native, actionable retention reporting inside Klaviyo, things like repeat rate and TTSO tracking by flow. Review collected by and hosted on G2.com.

I really like that Klaviyo provides a lot of features apart from email marketing, like the ability to review products, which is great because we can select the reviews and show them on our site. Creating campaigns and using them to trigger emails is super useful. It's also great to have a way to give discount coupons to customers. The initial setup was pretty easy.

Their UI to make the templates is not that great. They can work on their UI and make it more decluttered. Review collected by and hosted on G2.com.

I find Klaviyo incredibly flexible and it integrates really well into our other systems, especially with Shopify, which we use for our website platforms. It does a great job of creating unique email flows, allowing us to tailor our messaging based on what users are doing at that time on the website. The initial setup was super easy.

The user experience can be a little glitchy when editing the emails. The email editing portion of Klaviyo isn't the greatest, copying and pasting text can be a little bit of an issue. It just modifies the text in terms of color, font, etcetera. It doesn't offer a ton of unique options either. It's really kind of pick a template or create a template. There aren't any other unique features about it. Review collected by and hosted on G2.com.

Basic flows require little to no technical skills. I can set up basic flows in just a few minutes. Review collected by and hosted on G2.com.

It does not want to send an SMS campaign to users who have not submitted a form via Klaviyo. I would also appreciate multilingual forms and flows. I think it also requires some works when it comes to web accessibility (adhering to WCAG success criteria). Review collected by and hosted on G2.com.

I greatly appreciate the opportunity offered by Klaviyo to customize email marketing flows, an aspect that allows strategies to be adapted to the specific needs of customers effectively. Furthermore, Klaviyo's ability to analyze customer behavior is extremely useful; I can segment customers based on type when the information is correctly provided by the CMS and analyze important metrics such as Life Time Value (LTV) and the average time between orders without the need to incorporate other third-party tools. The ease of initial setup is another great advantage of Klaviyo, which I rate 10 out of 10, demonstrating how simple and intuitive it is to start using the software. Overall, Klaviyo is a very advanced software that I would definitely recommend to friends or colleagues; I would give it a score of 10 out of 10. Review collected by and hosted on G2.com.

The price is steadily increasing and if the return on investment does not grow proportionally, it can become a problem. Review collected by and hosted on G2.com.

I love how easy it is to integrate Klaviyo with e-commerce platforms like Shopify and WooCommerce, making the setup process very straightforward thanks to their dedicated app. The ability to generate subscriber lists from email widgets and send marketing emails within groups is incredibly beneficial, enhancing my marketing strategy's efficiency. I find the dashboard to be very user-friendly, simplifying the process of managing email campaigns and creating lists directly within Klaviyo. This intuitive interface is a significant advantage for merchants looking to streamline their email marketing efforts effectively. Review collected by and hosted on G2.com.

I find Klaviyo to be somewhat expensive compared to its competitors, and I feel they could lower the pricing. Additionally, the email list capacity offered is lower than what is available with other services, which limits my options for managing a large subscriber base effectively.

The software allows you to create dynamic and complex email flows and campaigns. With enough attention given to your strategy, you can create a cross-selling machine based on customer activity. I also love the cross connection to other great apps and software to have a better understanding of your customer. Review collected by and hosted on G2.com.

There are 2 things that I find frustrating. 1) Understanding the software to maximize it to the full potential it has requires a ton of knowledge of how the systems are connected to your marketing ecosystem. Understanding how flows work and how they connect to each other takes a lot of time or money to hire it out. In my company, I have a full-time staff member who uses about 50% of her time to manage the building/understanding process. Once built up, it will be easier to maintain and be a revenue generator. As a non-marketing person, I dislike how hard it is but understand but I get how necessary the complexity is. 2) When using other apps that integrate into Klaviyo I often have to pay massive premiums to have API connections. I already pay for Klaviyo and the other app in their premium tiers, it makes me feel nicked and dimed for something I already pay for. Review collected by and hosted on G2.com.

I like how Klaviyo combines powerful segmentation with real-time customer data, making it easy to send highly personalized messages at the right moment. Its seamless integrations and clear reporting also make it simple to test, optimize, and prove impact quickly. Review collected by and hosted on G2.com.

Klaviyo can feel complex and overwhelming at first, especially when setting up advanced flows or managing large numbers of segments. Pricing also scales quickly as your list grows, which can become challenging to justify over time. Review collected by and hosted on G2.com.
