Hi @Illia,

Thanks for sharing this question with our community.

I assume you’re referring to a Shopify newsletter sign-up section? If so, Klaviyo’s Shopify integration provides three options for syncing your signup forms to Klaviyo:

• Sync your default Shopify signup forms to a Klaviyo list 
• Add a Klaviyo form to your Shopify store (I understand you don’t wish to pursue this solution)
• Integrate a 3rd party signup form provider to your Klaviyo account.

The first option will guide you through getting your Shopify sign-up to funnel subscribers into your Klaviyo list. Also keep in mind, if a new subscriber sign-ups through a Shopify form, they must confirm their subscription before they’ll be subscribed to a Klaviyo list. This is a part of Klaviyo’s double-opt in process. You can change your Klaviyo list to single opt-in if you wish to circumvent the confirmation step altogether, although it is not recommended.

I hope that’s helpful and thanks for being a member of our community.
