Amazon Merchant Services automatically sends out Shipment Confirmation emails to your customers once their order has been updated and marked as Shipped within Amazon. This is a setting that cannot be changed.
To prevent buyers from receiving multiple notifications with the same information, Amazon has asked that we do not allow notifications to be sent from ShippingEasy.
That said, ShippingEasy can help you complete the circle with your customers. The Amazon Seller Suite features Reputation Management. These automated emails empower you to request product reviews and seller feedback. Learn more.
