I find it hard to imagine that Klaviyo, a major company, could create an app so riddled with bugs. My emails couldn't get customers to my website, a feature that even a $5-a-month email marketing app could provide. But in the eyes of Klaviyo's software engineers, this was an insurmountable obstacle. This was an unforgivable mistake. Klaviyo's new feature required me to enter my phone number before logging in. I don't understand which incompetent engineer came up with this.

Klaviyo has been a game-changer for our Shopify store! Setting it up was seamless, and the integration with Shopify works perfectly. I love how easy it is to create professional-looking email campaigns with their drag-and-drop editor, while still having the flexibility to customize with advanced features. The automation flows (like abandoned cart, welcome series, and post-purchase follow-ups) run smoothly and save us so much time. On top of that, the customer segmentation tools are extremely powerful — we’re able to send highly targeted campaigns that actually convert. Since switching to Klaviyo, we’ve seen a clear improvement in both engagement and sales. If you’re running a Shopify store and want to take your email marketing to the next level, I highly recommend it.

After installing, the log in process is not working. I forgot my password so I reset my password. The link for resetting the password was received after an hour. Besides, verification code is not sent instantly. I have to wait almost an hour. By the time I typed in, it said "type valid code".

Nous utilisons Klaviyo depuis plus de 6 ans pour nos campagnes et flows emails. C'est assez intuitif et des améliorations sont régulièrement faites. Facile de connexion avec Shopify.

Christina answered all my questions quickly and thoroughly. I was confused about updating email flows and I learned that updating a flow that is set to "live" means that my updates were made in real time and will send to designated customers according to each flow. Thanks for the help, Christina!

Danielle M was incredibly helpful and very patient with me as i navigated creating some segments and profile properties for my welcome flow. She was so helpful, continuously sending me examples, and even klaviyo blogs to go through the process, not only this, but she was helping me go through it step by step by providing me with answers, screenshots and double checking what i was doing. Amazing service, i'm so glad i always have help from the klaviyo support team.

This is a must have marketing app! The look and feel of the emails alone is amazing, but it's the automation that puts this app over the edge.

A fantastic platform to use. The reporting functions and level of details it goes into is great. What's more, their tech team and response to issues is great and very thorough. We're really happy with it and recommend it highly against other popular apps we have used previously.

ZERO actual help...but a whole lot of emails about reviewing them. And they're still sending me a bill after uninstalling over a month ago.
