I was unable to receive verification codes when logging into my account. Kalviyo teams helped me figure it out.

I'm unable to receive verification codes when logging into my account, and I've contacted suppor and submitted tickets t multiple times but without receiving any response. Very disappoint!

Found this to be far better than Mailchimp and they seem to be always improving the features and have so many options to customize your email design. I love how easy it is to set-up A/B tests, the integrations, the analytics, and the new AI tools as well, not to mention incredible customer service if you ever have an issue (or in my case, accidentally permanently delete something).

Aside from the fact that it is kinda expensive from what it offers, most of the services offered like help desk, reviews and email are all mediocre and mostly only offer basic features. It is also unneccessarily complex to setup at first. Once you do the initial setup, it is mostly fine to use but I would not rely on it for anything other than email maketing.

trying to set up 10% discount pop up for my shopify website has been a bit tricky. thought it was finished when a pop up says "Klaviyo onsite tracking must be enabled on your website to display your form." support says it needs to be done from the shopify website, shopify support says it needs to be done in klaviyo. It started off easy

I followed explicit instructions from Klaviyo support to resolve a configuration issue. That guidance resulted in service interruption and an accelerated billing cycle. Despite clear communication records, this is now being treated as a “customer-initiated change.” This is extremely disappointing and uncomfortable as a paying customer. I hope Klaviyo will review support-led actions more responsibly.

We switched to Klaviyo in order to use Email Marketing & SMS within one app and it has been such a smooth transition. We love the ease of use that the app offers as well as the customer service. We frequently attend their seminars and find their articles and resources very helpful.

Klaviyo is hands-down one of the most powerful email and SMS platforms out there for ecommerce. The depth of their analytics is where they really shine. From revenue attribution to flow-level performance and segmentation insights, Klaviyo gives you the kind of data that actually helps you make smarter decisions and squeeze more sales out of every campaign. The segmentation and automation capabilities are excellent, and once you know your way around the platform, it becomes a serious growth engine. If you care about understanding customer behavior and optimizing lifecycle marketing, Klaviyo is hard to beat. That said, pricing is the biggest downside. Being charged for all profiles in your account—even ones you never email—can feel frustrating, especially for growing brands with large lists. It would be much more fair (and sustainable) if pricing were based only on the profiles you actively send emails to. Overall, Klaviyo is an elite tool with best-in-class data and performance. If they adjusted their pricing model to better reflect actual usage, it would be close to perfect.

Klavio would't import my subscribed email list. It's how to import contacts from shopify instructions absolutely did not work.

Great email tool! We have over 30,000 subscribers and the continued focus on customer experience from Klaviyo has helped me better serve my customers.
