To confirm IncaMail digital registered messages, the sender and recipient are sent a PDF receipt signed by Swiss Post in separate e-mails. These receipts provide secure cryptographic proof of the history of a registered message. Unlike receipts for registered letters, the receipts also prove that very specific content and attachments were sent with the registered message. IncaMail saves neither receipts nor registered messages. It is up to the sender and recipient to keep them if required.
The following receipts are created and sent:
- Delivery receipt: The message has reached IncaMail.
- Acceptance receipt: The recipient has accepted the message.
- Verfallquittung: Die Annahmefrist ist ohne Aktivität der Empfängerin / des Empfängers abgelaufen.
- Expiry receipt: The acceptance deadline has expired without any action by the recipient.
In the event of an interoperable transfer via another recognized delivery platform as per communication with Swiss authorities, the receipt may also be sent by the other delivery platform.
