The nature of USPS's Postal Bulletin is best described as a guide for postal regulations because it serves as an official publication that informs employees and postal stakeholders about any updates, changes, and clarifications regarding postal policies and practices. This bulletin provides crucial information on various aspects of postal service operations, such as rate changes, operational changes, and updates on postal regulations. By disseminating such information, it ensures compliance and understanding among postal workers and other relevant parties, thereby facilitating smoother operations within the postal service.

The other options do not capture the primary purpose of the Postal Bulletin. While a mailing list, promotional newsletter, or training manual may serve specific functions, the bulletin uniquely focuses on regulatory information that is essential for maintaining the standards and practices of the postal service. Its role is vital in keeping personnel informed and aligned with the agency’s guidelines and regulatory environment.
