"Effortless Ecommerce Integration, Needs Pricing Adjustment"
What do you like best about Klaviyo?

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.

What do you dislike about Klaviyo?

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.

"Effortless Email Campaigns for Small Teams"
What do you like best about Klaviyo?

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.

What do you dislike about Klaviyo?

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.

"The best emailing software but with a high degree of control"
What do you like best about Klaviyo?

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.

What do you dislike about Klaviyo?

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'm always productive when working with Klaviyo"
What do you like best about Klaviyo?

The UX is perfect for productivity. You'll find everything you need in one or two clicks. I work with several tools integrated to Shopify and in some you need several clicks to get what you need. That doesn't happen with Klaviyo. I always know where I'm at, can jump easily from section to section. Also, the level of customization you can do for emails and flows is something I haven't seen on any other platform. I think it's because all the native integrations they have. Customer support always reply back to my tickets in a timely manner and usually they have good answers and solutions. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

It is very VERY annoying that loading a segment takes that long. There are other platforms much less powerful in customization like Omnisend that load a segment in less than a second. Klaviyo takes minutes and we don't even have a database that big. Also, there are unexpected glitches here and there that are gone before you report them but in the meantime they slow you down. Like when exporting a list or segment the list of properties overlaped each other making it impossible to click on them. The thing is, even with all the bad I wouldn't choose any other platform for ecommerce. Klaviyo is the perfect fit but it's not perfect. Review collected by and hosted on G2.com.

"Powerful marketing automation platform with excellent segmentation"
What do you like best about Klaviyo?

Klaviyo offers advanced segmentation and automation tools that make it easy to deliver personalized campaigns. I really value how user-friendly the platform is compared to other marketing automation tools, and the integration with e-commerce platforms like Shopify and WooCommerce is seamless. The detailed analytics and reporting also help optimize campaigns effectively. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

The pricing can get expensive as the contact list grows, which may be challenging for smaller businesses. The email builder is good but could offer more flexibility and design templates out of the box. Review collected by and hosted on G2.com.

"Gets the job done and the interface is fairly easy to use!"
What do you like best about Klaviyo?

I think it's easy to use and makes our marketing very effective and efficient. I really appreciate the attention they give to the security of your account, too. Also, it's easy to use their inbox and respond to cx right then and there. Also had 2-3 experiences with the support, and they are also supportive and fast.

We use Klaviyoo on a daily basis to send and manage email and SMS campaigns. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

When trying to log-in and you have 2FA turned on, it will ask you to put in your account and then you got to a screen that is to confirm your number to send the OTP, now you have to click and then it will send you the SMS with our code.

I know a very small thing, but it should be sent right away! Why wait for another click? Review collected by and hosted on G2.com.

"The Best Email Client I've Ever Used"
What do you like best about Klaviyo?

Klaviyo has everything, its easy to use once you know what you're doing. Implementation is easy but takes time because of the automation, and the customer support is amazing and so patient even with technophobic owners at the company. It made email marketing a breeze. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

Downsides are the implementation, you can sign up and go, but you'll miss out on the best features. Really not a downside. Review collected by and hosted on G2.com.

"Amazing service"
What do you like best about Klaviyo?

Klaviyo is an easy to use platform that helps both our email and sms channel. The interface is great and the ability to create powerful segmentation has improved our customer engagement and review. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

It can be expensive as your list grows, so it's worth closely monitoring performance to ensure ROI. When building segments, the ability to create based on a calendar date isn't available yet, this would help us improve some customer journeys to ensure we are speaking to customers at the right time.

"Very User Friendly ESP"
What do you like best about Klaviyo?

This platform is very user-firendly, mostly everything is out of the box which is a big win for small teams with limited dev support. There are so many things I can quickly and efficiently do with it for campaigns, flows and segmentation. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

The trade-off of being easy to use and out of the box, is that you loose out on being able to tailor to your exact needs. I will also say that so many of the features are ALMOST there, but not quite. I am also lacking some out of the box integrations with tech stack, BazaarVoice for one, and some of the integrations are limited. Review collected by and hosted on G2.com.
