Hello, 

I have just signed up and was wondering if anyone who has been using Klaviyo could tell me whether or not the customers that are not signed up to your marketing emails, but do receive a transactional mail through Klaviyo count as a “contact” for Klaviyos billing purposes?

We want to send all transactional emails through Klaviyo instead of Shopify, but obviously that would add a lot to the cost if this is the case (with a lot less value) when you consider that only 5/10% of them actually sign up to marketing emails. 

Thanks for your help!

Alex
