Ovcio review for Klaviyo: Email Marketing & SMS

Advantage: easily integrate with Shopify. Disadvantages: 1. This app is way more expensive than other marketing automation apps. 2. The app will send the "Subscription confirmation" email instead of the emails you configured to send. If you wanna disable the "Confirmation" option, you have to upgrade. And there is no information about this which wasted tons of my time to investigate my email marketing problem.
