How Does Klaviyo Begin Data Collection + Adding Users to a List and Flow (Shopify)

Hi @HAM3X ,

Thanks for your question in the Community and I hope to provide some information regarding your questions!

Although you could manually import customers from a list onto Klaviyo, it is also an automatic process that users will go into your data once they do a certain action or enter a certain flow.

First, I would ensure that you are directing the Shopify sign-ups to a list. You can verify this by navigating to Integrations > Shopify under Collect Subscribers. The list in question needs to be selected here:

Also, if you are using a Shopify 3rd party theme, your theme's default signup forms must also apply the Newsletter tag to new subscribers in order for Klaviyo to automatically sync these subscribers to a Klaviyo list. You’ll want to integrate it to Klaviyo by following this guide. The hidden input tag, <input type="hidden" name="contact[tags]" value="newsletter"> should live within your form’s input group. If this has been done correctly, those filling your Shopify form should have Newsletter under the Shopify Tags custom property on the user profile.

Below is more information on lists and segments:

Flows will start depending on how you have them set up. There are conditions and triggers that can be setup within flows that, if a user meets the criteria or triggers the action, will enter and exit the flow allowing you to receive their data as well. Here is a guide about flow triggers and filters as well!

Here is another community post detailing how to make a list-triggered flow as well as additional details that pertain to your questions!

Hope this helped with your question and thanks for being part of our Community!
