In response to the proposed rule, the Postal Service received one formal comment. The comment and response are as follows: <E T="03">Comment:</E> The comment was generally in agreement with retiring the manifest mailing system, however, the commentor questioned whether some smaller businesses may face challenges with the technology transition. <E T="03">Response:</E> The Postal Service has taken proactive steps to support these customers through the Intelligent Mail® for Small Business Tool (IMsb). The IMsb Tool is a free, web-based application designed specifically for small business mailers. It requires no software installation or downloads, making it accessible to businesses with limited technical resources. The tool generates unique Intelligent Mail barcodes (IMb) for use on address labels and mail pieces, and it features a simple, step-by-step interface that guides users through the process. Additional benefits include easy access via standard web browsers ( <E T="03">e.g.,</E> Google Chrome), no need for specialized software or technical expertise, and is a cost-effective solution for businesses with limited budgets. For further guidance, users can refer to the IMsb User Guide, located on the IMsb Tool landing page, available on PostalPro at <E T="03">https://postalpro.usps.com</E> . This tool represents a meaningful step toward ensuring that small businesses are not left behind in the Postal Service modernization efforts.

The Postal Service is migrating customers to Electronic Documentation (eDoc), Full Service, Seamless, and eInduction, for Letters, Cards and Flats. Options for Package customers are USPS Ship and Click-N-Ship. Mailers of Letters, Cards, and Flats can reference Mail.dat/Mail.XML Technical Specifications posted on PostalPro.
