Which of the following is NOT a required feature on USPS Marketing Mail?

The correct answer is the return address, as it is not a required feature on USPS Marketing Mail. While including a return address can be beneficial for businesses to ensure recipients can send back correspondence if needed, it is not mandatory for marketing mail pieces. This flexibility allows businesses to choose whether or not to include a return address based on their specific mailing strategy or cost considerations.

In contrast, PRSRT STD marking is important for ensuring the mail is processed at the appropriate discounted rates. Weight limits are essential to keep mail within acceptable ranges for delivery and pricing purposes, ensuring compliance with USPS requirements. The permit imprint serves as proof that postage has been paid for the marketing mail, which is significant for bulk mailing processes. Hence, these features help in processing and identifying marketing mail, distinguishing them from the optional return address.
