Zivver can make function available for a proof of delivery report.

The proof of delivery report has these main purposes:

• Inform the sender of a message what the status is of the delivery of their (notification) message.
• Give the sender of a message detailed information about the delivery process of their message.

This is the contents of a proof of delivery report.

• A summary that shows whether the message was indeed sent and delivered and whether it was encrypted in transit.
• Zivver event flow from message creation onwards. That includes, for example, delivery failures.
• NTA 7516 message status if relevant.
• Zivver message revocation status.

Remarks

• Zivver sends Inbound Direct Delivery and NTA messages as plain text.
• If a recipient’s email server does not honor DSN (delivery status notification) requests, Zivver does not detect delivery failure of a message. Thus, the log does not contain such failure.
