I don't write a review that fast. In the last two years I've tried different ESP's.. and boy.. I wish I knew Klaviyo sooner. It would have safed me a lot of money and the experience/data you see it 10x when you compare it to other ESP's like Sendcloud, activecampaign, mailblue etc. Klaviyo is my go to, forever. The fact that they offer free 300 people is already amazing, because with these 300 people I could already pay for the subscription. So if you're in doubt, stop it. I've tried a lot and this is just the best. Haven't got the chance to speak to the support so I can't give advice on that. But the fact that I don't know is already a good sign ;)

Across my career, I’ve used so many tools for email. None of them compare to Klaviyo. Right out of the gate, Klaviyo helped us stream down the number of tools we were using for various different purposes, it ultimately helped save us money, as a small brand, this was awesome. There’s so many features to learn about and use, from email capture to segmentation, emails and automations, etc. Is there a learning curve, definitely, but once you’re in it and you go through the help and strategy docs it’s hard not to see email become a bigger revenue driver than other channels.

I use Klaviyo to manage my customer connections and it's been easy to use, has simple suggestions for quality marketing, and free + paid options. Very satisfied so far.

Klaviyo is a GAME CHANGER. I switched from Mailchimp mostly because of the ease of install and incredibly value you can get from the turnkey integrations that help you leverage customer and prospective customer data from other apps like Octane AI and Okendo in particular. Converted and not once looked back.

Klaviyo is by far the best ESP you can use for ecommerce. It is incredibly intuitive, allows you to see all of your customers data, and has the most opportunity for segmentation that I've seen to date.

Klaviyo is the go-to solution for email and SMS marketing for Shopify stores. I love it so much. It has a reliable and seamless Shopify integration and has been an integral part of our growing online business. I couldn't do without it.

I revised my review after Danielle reached out to me and went above and beyond in explaining what was more of a misunderstanding than anything else. As mentioned in the previous review, the product is excellent. I do however question if something can not be done about the pricing once we get into a very high number of subscribers (say at least 50k). I don´t think the pricing "scales" well....

Simple to use, great content, and very efficient and convenient with my Shopify store! The only thing I wish they would add is an "undo" button while building templates. Other than that, it's great!

So far so good! Klaviyo has been super easy to learn and create flows. I love how much you can get done in just this one app! I just launched my first campaign and it was very painless!The only thing I wish is that we could get customer support on the free plan because I have questions on the paid plans with no one to ask them to. Overall, if you're new to marketing and creating flows, this is the app for you. Klaviyo lays it all out for your success.

I use this app for email marketing and email acquisition. It's great once you know how to use it. They only thing I had an issue with was actually learning how to use it and understanding the tools, which is a lot!! Nice to have a tutorial.
