Hi @bea123 ,

Welcome to the Community.

Just to clarify, that page is going to be visible only on your end so if you do not want to collect email subscribers automatically to a list then yes you would just not check the box. 

Do you currently have a form linked to a list in your Klaviyo account? 

Hi @alex.hong, 

thank you for answering! We’ve figured it out and unticked the box. 

However, some people are still synced to this list - even after we unticked the box and removed the tick box from shopify as well. We do not have any forms live at the moment. So, logically, there is no way why people are synced to my newsletter list.

Any idea why this happens? 

Hi @bea123 ,

Interesting. Can you click on a user’s profile and share with us what activities they have done that link to the list they are added on? Could it be that they have registered somewhere in the past or from an old form?

@alex.hong, the only common thing all of the profiles have is “$source: shopify” and (most of them) “fulfilled order” from around 3 days ago. 

We never had a form on the website. The only way you could subscribe was the tick box during the shopify checkout. But this tick box is removed from the frontend since yesterday. 

Hi @bea123 ,

It is most likely coming from Shopify itself and not necessarily a form you have made. The purchase event comes a few days before the actual subscription event and this would not have happened if this was coming directly from your integration. They would be subscribed directly after they purchased on Shopify.
If you make sure the "newsletter" tag is not added to any profile in Shopify anymore, then they will not enter your Klaivyo platform. This is how Shopify knows to send the profile to us. If you remove that from Shopify this should stop. Events that come over from Shopify such as placed order and started checkout are not contingent on that profile property. They are separate mechanisms that will not be affected by removing the "newsletter" tag.
