What is the role of delivery confirmation?

Delivery confirmation serves the critical function of verifying that mail has been delivered to the recipient. This service is essential in various mailing contexts, especially for important documents or packages where proof of delivery is necessary. By providing a receipt or notification that indicates the mail was successfully delivered, it offers assurance to both the sender and the recipient. This documentation can be particularly valuable in cases of disputes or for tracking purposes, ensuring that items are received as expected.

In contrast, while reducing mailing costs, ensuring privacy of the sender, and expediting processing times might seem beneficial for mailing practices, they do not specifically pertain to the direct verification of mail delivery itself, which is the primary purpose of delivery confirmation.
