This function is available if Zivver makes it available for your organization. Speak to your representative at Zivver.

The proof of delivery report has these main purposes:

  • 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.


  • 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.
