Add New Square Customers to Klaviyo Subscriber List

This step automatically watches for new customer creations in your Square account and runs every hour to check for updates. When a new customer is added to Square (either through online purchases, in-store transactions, or manual entry), this trigger captures their profile information including email address, name, and contact details. The trigger passes this customer data to the next step for email validation before attempting to subscribe them to Klaviyo.

This step automatically checks whether the new Square customer has a valid email address before proceeding with the Klaviyo subscription. The filter 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 doesn't have an email address (like cash-only in-store customers), the workflow stops here to avoid creating incomplete records in Klaviyo. Customers with valid emails proceed to the final subscription step.

You'll need to configure which Klaviyo list you want new Square customers subscribed to by selecting from your available lists in the dropdown menu. The step automatically maps the customer's email address from Square and sets their subscription consent to "SUBSCRIBED" for email marketing. This creates a new profile in Klaviyo (or updates an existing one) and adds them to your chosen list with marketing permissions enabled. The subscription includes proper consent documentation for email marketing compliance.
