The experience with Klaviyo has been outstanding. The app works well with Shopify and allows for the most compete view of our customer experience. We have used other ESP's and this integration is top notch!

Klaviyo stated they have protections in place to keep bots from signing up creating fake emails. I am a small business and my email is full of fake emails. I try to delete them but they don’t disappear. I can’t keep ahold of any one in support until I upgrade and pay a monthly fee or lower the amount of emails in my account which is not working. I guess you can’t get help unless you pay them. It is a difficult platform to use also. The best option is to delete my entire account and go to a different email provider. I don’t want to work with a company that can’t help unless you pay them!!
