Which unit must process commercial or business-related mail customers?

The Business Mail Entry Unit (BMEU) is specifically designed to process commercial or business-related mail customers. This unit plays a critical role in handling bulk mailings and ensuring that businesses can efficiently utilize postal services for their mailing needs. The BMEU facilitates the acceptance of large volumes of mail, offering automation and processing options that are tailored to meet the requirements of commercial clients.

Businesses often have unique mailing requirements, including the need for different rates, service levels, and preparation standards. The BMEU ensures that these customers receive specialized support and guidance through the mailing process, from entry to delivery. They are equipped to handle various types of business mail, whether it involves marketing materials, invoices, or other communications, making them an essential resource for commercial mailers.

Other units, such as AMEU (presumably Alternate Mail Entry Unit), CMU (Customer Mail Unit), and SME (Small Mail Entry), do not specifically focus on business-related service needs and may cater to different types of services or mail categories. Thus, the BMEU stands out as the correct choice for processing commercial or business-related mail.
