I can always count on Klaviyo support to help me out. This time, it was about a webhook that wasn’t working. No matter the issue, they respond quickly and always manage to resolve it. Thank you!

Lucas Reymond was fantastic
Why so many 1 Stars? Sheesh! There are lots of bad reviews here! I signed up a month ago and found Klaviyo far superior to the other four platforms I used in the past. Lucas Reymond was fantastic at helping me get my account warmed up. The live chat has been a lifesaver; I've been using it for over an hour every day for the last three weeks. Every other app I use on Shopify works with Klaviyo, so I no longer have to use annoying Zapier.

As layperson
As layperson, I find their software very easy and intuitive to use. It has taken a bit of time to set up and learn about campaigns and flows but I really like that I can really see everything going on with my website. I can implement changes based on what I can see my customer interactions are.
