“Integration Strengths And Advanced Flows Balanced By Pricing And Usability Issues”

Klaviyo has been a strong addition to our marketing stack, making it easier to manage campaigns and automate customer journeys. The integrations with Shopify and our third-party apps has been pretty seamless, and the data-driven insights help us refine targeting and improve ROI. The analytics and segmentation are powerful, though at times the reporting dashboard can feel a little clunky and slow when working with large datasets like lists with tens of thousands of contacts and multiple custom fields. Overall, it has streamlined our email (sadly we can't use SMS on Klaviyo) marketing, driving measureable growth in engagement and sales.

Klaviyo Likes & Dislikes

Like

1. Advanced segmentation and personalisation. It's easy to create targeted flows based on customer behaviour and purchase history, which significantly improves engagement. 2. String e-commerce integrations. Shopify and the third-party applications we use seamlessly connect to Klaviyo which ensures smooth and accurate campaigns and real-time data. 3. Flow-builder and automation. The drag-and-drop builder is intuitive and makes it super simple to set up and edit existing or new customer journeys and we don't need devs! 4. Data-rich analytics. Clear revenue attribution and performance tracking for campaigns and automations is pretty much spot on.

Like

There are a lot of built in, out of the box, solutions for Shopify that make it an amazing time/performance saver.

Like

The platform is very intuitive and easy to use for any level of CRM team member. The help guides and training is so thorough that you can learn the platform pretty much by yourself, but the CSM is always available and answer quickly if you have any queries or need help.

Dislike

1. The list builder can be slow sometimes when building larger lists. We use large datasets, in the hundreds of thousands and this will often slow down our workflow on Klaviyo. Klaviyo builds the in background and prepares exports in the background, but sometimes we just need to get stuff done quicker. 2. Pricing scales up as lists/profiles grow, but nonetheless it can become very costly, and although email marketing is profitable to our bottom line, competitors to Klaviyo are priced (sometimes substantially) lower. 3. Some advanced features require a very steep learning curve. There's a lot of nuances to segmentation building for example and it can get confusing fast. Klaviyo's AI feature to help you build segments helps, but it can often get it wrong and unless you know what you're looking it - if you rely too heavily on the AI-built segment, you'll get the wrong results.

Dislike

Once you move past its built-in support for Shopify, it can be challenging to implement anything custom.

Dislike

I have always said I'd like to see more from the Push Notification side of Klaviyo, I think sometimes when things are launched in infancy it can be good to start testing but also just leaves me wanting more

    Klaviyo Is the Gold Standard for DTC Email Marketing

    5.0
    Aug 12, 2025
    Compared to other ESPs I've used for email marketing specifically, Klaviyo is truly the gold standard. They're constantly rolling out new features that make such a difference and that seem to come from direct customer feedback. For that reason I find it by far the best platform for everyday use.
