There is no way to disable Shopify shipping confirmation e-mails. If you also have e-mail notifications enabled in ShippingEasy, your customer will receive two shipment notifications. We have two great solutions:
Customize your ShippingEasy confirmation emails:
If you would like to continue to send the e-mail from ShippingEasy, you may want to change the text on the Shopify e-mail so it doesn't feel like a duplicate. For example: "Thank you for your order..."
Turn off shipment confirmation emails in ShippingEasy:
If you would like to only send the e-mail from Shopify, you can turn off the notification in ShippingEasy.
