Hi @Soco ,
You can disable shipping notification emails in Shopify in two steps. From your Shopify admin, click Settings in the lower left. Then, click Checkout. Scroll down to Order Processing and select Automatically fulfill the order’s line items; then, uncheck Notify customers of their shipment below that setting. Then, navigate back to the Settings page and click Notifications. Scroll down to Shipping and uncheck the Out for delivery and Delivered options.
