Hi @Optimotive WS,

As a first step, I’d ensure on your Shopify integration that you’ve ticked the checkbox to send those who have accepted marketing on your Shopify store to be added to you list. You can do so by going to Integrations > Shopify. Here’s what that page should look like if this is enabled:

Have these users fully completed the checkout process (placed an order)? By default, Klaviyo only syncs those who have fully completed their purchase to you newsletter list. So abandoning a checkout, equates to abandoning intent to subscribe.

Hi, 

I have the same problem! I use the Newsletter form from Shopify (not the one from Klaviyo). But there is no Confirmation mail going out. And I have all the Integration settings in Klaviyo set correctly.

Thanks for your help!

Hi @AmazingBB 

Sorry for the delay here! 

Are you using a 3rd party Shopify theme? That can sometimes change how Shopify forms and Klaviyo sync. 

If you are the update is simple you need to add the Newsletter tag to new subscribers in order for Klaviyo to automatically sync these subscribers to a Klaviyo list. The tag is added to the form’s input:

<input type="hidden" name="contactctags]" value="newsletter"

You can find more guidance on our Integrate with Shopify doc.
