Which type of verification is performed on every mailing?

The correct response is based on the standard practices involved in the mailing process, particularly focusing on the importance of mailpiece reviews. A mailpiece review is conducted to ensure that all aspects of the mailing adhere to set guidelines and standards. This involves checking the format, addressing, postage requirements, and the contents of the mailpiece.

Mailpiece reviews are essential because they help to ensure that the mailing will be processed correctly and delivered to the intended recipient without issues. They can prevent delays and returns that might occur if the mailpiece does not meet the postal service's criteria.

While customer address verification, weight verification, and delivery confirmation are integral parts of certain mailings or procedures, they do not occur on every single mailing in the way that a mailpiece review does. Address verification might be necessary for specific circumstances or systems that require updated customer information, weight verification is only needed based on the type of mail and its requirements, and delivery confirmation relates to tracking post-sending rather than being a pre-mailing verification step. Therefore, a mailpiece review is the most consistently applied type of verification across all mailings.
