What I like most about Klaviyo is how powerful its segmentation and automation features are, while still being relatively easy to use. The Shopify integration is seamless and lets us use real customer data to create highly targeted campaigns and flows. The flow builder is a standout as well; it makes it straightforward to set up automated sequences such as abandoned cart, post-purchase, and win-back campaigns. I also appreciate the analytics and reporting, which help us clearly see the revenue generated by each campaign or flow. Review collected by and hosted on G2.com.

The biggest drawback is the pricing, which can get quite expensive as your contact list grows. Some areas of the interface can also feel a bit complicated when you’re managing lots of flows or segments, especially if you’re new to the platform. I’d also like to see more advanced built-in reporting, or at least easier ways to analyze performance across multiple campaigns without having to export the data.

The extreme customization within the website makes it absolutely amazing to use for our company. We don't really use any third-party integrations or apps, but the overall performance of the functional music has been absolutely amazing. It is so worth what we pay for, and it does so much for our company. It essentially pays for itself since email marketing is one of our strongest channels. Review collected by and hosted on G2.com.

There's nothing specific we don't like about Klaviyo. There was a bit of a learning curve, but after that it was super easy to navigate through and the support is amazing for when you need help. Review collected by and hosted on G2.com.

Klaviyo is the gold standard for ecommerce email and SMS marketing. Its segmentation is especially powerful, letting you slice your audience using a wide range of data points. The flows are intuitive to build and genuinely help drive revenue. The analytics provide clear attribution, and the integrations with ecomm platforms and other tools keep the data clean, consistent, and connected. I use it every day, and it just works—I rarely run into issues, and I’ve never needed to reach out to customer support. Review collected by and hosted on G2.com.

Pricing is the biggest pain point. Costs scale quickly as lists grow and it can feel disproportionate during high growth phases where you're paying a lot more without a step up in features. It's hard to justify that cost to stakeholders when the costs increase. That said it earns back in results - but pricing could be more flexible. Review collected by and hosted on G2.com.

1: The design and template building tools work as intended and are so efficient, with handy shortcuts such as universal blocks that anybody on my team can access when designing new campaigns.

2nd favorite: setting up segments is so easy with the AI assistance.

3rd: the customer service has always been quick, friendly, and useful. Review collected by and hosted on G2.com.

Anyone viewing a preview URL of a campaign needs to have a Klaviyo account and be logged in. Some team members are too busy to hassle with an authenticator app cycle and a a personal login with Klaviyo to preview eblasts. Maybe a password protected URL preview would suffice, eh?

I like the ease of use that Klaviyo has. I also value all the metrics it provides me to see how the campaigns are performing, and finally, the integrations they have with other platforms like Shopify. Review collected by and hosted on G2.com.

There are times when the delivery rate is not so good, and sometimes the team can't tell me why it is. As for Gmail, it doesn't have good sending rates, and I would like you to give me a solution to improve all that, like giving me IPs that work better. Review collected by and hosted on G2.com.

Klaviyo's dashboards and functions are so user friendly. Even if you don't know exactly where something is, you can usually find it pretty quickly because of how well everything is laid out. The audience segmentation tools are amazing and it's easy to make attractive flows, even as a beginner.

They have a ton of documentation that is easy accessible if you don't know how to do something and customer support is fast and friendly when you do run into an issue! Review collected by and hosted on G2.com.

I love that they are adding so many new features, but I wish I could better know how they function before we invest the money and time to implement them. (Loyalty, Reviews, etc) Review collected by and hosted on G2.com.

From our financial service operation perspective, Klaviyo stands out most for its mature audience grouping capability and built-in privacy control mechanisms that fit regulated businesses perfectly. We are able to divide our investor clients accurately based on actual investment portfolios, risk appetite and client service cycles, so we can deliver targeted market insights and service reminders instead of widespread irrelevant emails. The platform keeps full records of user subscription choices and every outbound communication trail, which fully satisfies GDPR, MiFID II and local BaFin supervision demands, and largely cuts down our workload when sorting out audit materials. Its easy-to-use editing module also lets our team quickly finish polishing and arranging compliant financial notification content. Review collected by and hosted on G2.com.

There are not enough professionally designed email templates suitable for financial industry scenarios. It cannot achieve stable one-click data linkage with our in-house client management system, so we have to spend extra time on manual data supplementation. It is not convenient to set up pre-release content review rules for financial marketing content. Meanwhile, its local statistical analysis reports cannot fully match the data sorting standards used in German financial institutions, requiring extra rearrangement before submitting audit documents.

Klaviyo is the backbone of how we run retention for DACH ecommerce brands. The Shopify integration is deep enough that we can build segments and flows on real customer behaviour without stitching tools together. Flow builder, segmentation, and the predictive analytics layer (expected next order date, CLV, churn risk) are what we lean on every day. The Klaviyo MCP has changed how we work as well, we can pull performance, build segments, and check flows directly from our AI stack across all client accounts in one place. For an agency, that compounds fast. Review collected by and hosted on G2.com.

Pricing scales aggressively with active profile count, which makes the math painful for brands sitting on large lapsed segments they haven't activated yet. The AI features are uneven, some are genuinely useful, others feel half-shipped and gated behind higher tiers. WhatsApp still has to be solved through a third party in Europe (we use Chatarmin), which means more integration glue than I'd like. And reporting flexibility is limited enough that we end up building our own dashboards on top of the data anyway. Review collected by and hosted on G2.com.

I use Klaviyo for marketing automation and love how it makes launching campaigns efficient, especially targeting my registered users and prospects who have interacted with my website. The hyper-personalization feature is phenomenal, outperforming other tools I've tried like Constant Contact and Mailchimp. I also appreciate the ability to launch further campaigns based on user behavior without losing track, which is crucial for reaching a wide audience efficiently and economically. The RFM matrix helps me easily determine which customers are likely to make orders, which simplifies my marketing strategy significantly. The initial setup was quick; it took just an hour to implement key flows and launch them, which is a big time-saver. I also use it with other platforms like Shopify and my website, and I find Klaviyo integrates very smoothly with these and other tools, like Adobe. Additionally, the new features they're launching, even in beta, are impressive, such as the campaign auditing feature that provides targeted prospect numbers even before we launch campaigns.

No, the beta version for live campaing audit is a real saviour Review collected by and hosted on G2.com.

Drag and drop builder, very intuitive, I can get my emails out without knowing coding. It is fairly priced IMO (I can see how people would think klaviyo is expensive, but we are able to generate a good ROI from the tool). It integrates really well with shopify, we have a bunch of automations enabled. The dashboard has good reports/insights that can be shared with management. Review collected by and hosted on G2.com.

Some known issues with klaviyo (from my own experience and folks I talk to), klaviyo is known to miss-attribute the revenue. Basically any order that goes out within a small window of your email going out, even if it came from a different channel altogether, klaviyo tracks it as it's own. So we always need to go back and look at further insights on shopify to see if klaviyo had anything to do with that order. And open rates aren't exactly a metric we would rely on (but this is more about apple/privacy filters than klaviyo I suppose) Review collected by and hosted on G2.com.
