Add New Shopify Customer Emails to Klaviyo List

This step activates automatically whenever someone creates a new customer account in your Shopify store, whether through checkout, account registration, or manual admin creation. The trigger captures all customer information including email address, name, phone number, and account details. No configuration is needed - it monitors all customer creation events and immediately passes the new customer data to the next step for processing. The workflow processes each new customer individually as they register.

This filter checks whether the new customer has a valid email address before proceeding to the subscription step. The system examines the email field from the customer data and only allows customers with non-empty email addresses to continue through the workflow. If a customer was created without an email (like a phone-only checkout), the workflow stops here to prevent subscription errors. Customers with valid email addresses automatically proceed to the final step where they'll be added to your chosen Klaviyo list.

You'll need to specify which Klaviyo list you want new customers added to by entering the list ID in the configuration field. The step automatically subscribes the customer's email address to that list with "SUBSCRIBED" consent status, meaning they're eligible to receive marketing emails. Find your Klaviyo list ID by going to your Klaviyo dashboard, selecting the desired list, and copying the ID from the URL or list settings. The system handles the API connection and subscription process automatically once you provide the list ID.
