Electronic Return Receipts
A USPS Return Receipt provides you with proof of delivery in the form of a recipients signature and information about the delivery address, date and time of delivery.
Mailform will provide you with an email notification when return receipts are available on your specific envelope(s) and the return receipts can be accessed digitally from your receipt page, or via your order history at www.mailform.io. Each electronic return receipt will have a "View" button available.
Separately, a return request can be accessed via the order tracking page at USPS.com.
