After I ended my subscription and deleted the app they continued to charge my card. After speaking with support they refused to give me a refund and gave the excuse that "we are a subscription service like Netflix" blah blah blah. Don't waste your time with these jokers and find an app that doesn't charge you an arm and a leg and actually gives decent customer service and doesn't make you jump through hoops to stop charging your card. You won't be receiving any refunds.

A very poor customer service :(
I'm brand new, I don't have any clients yet, and when I tried the Klaviyo app, all emails went directly to spam.
so...My ability to use this app is limited by this fundamental flaw. When I wrote to Klaviyo support, I received a reply that they did not offer any help if I had a free plan and suggested that I purchase a paid plan, however, since I'm a newbie, the paid plans are not good for me....
the very unpleasant situation.. it turns out their application requires payment to work at all in my case ... ugh bad attitude :(

I have used several different CMS programs and Klaviyo is by far the best one out there. It has so many amazing features and is very intuitive to use. I also love their customer support, they are always SUPER helpful and respond quickly. If you use Shopify and want to grow your e-commerce business Klaviyo is it!
