What aspect of postal services does the Bulletin address?

The Bulletin primarily addresses updates to postal policies. This encompasses a wide range of changes that may affect how postal services operate, including new regulations, changes in procedures, or adjustments to service offerings that are essential for both employees and customers to be aware of. Keeping the public and employees informed about policy changes is crucial for ensuring compliance and smooth operation within the postal system. Accessibility to accurate policy updates supports the infrastructure and integrity of postal services.

While the other options, such as new product launches, training programs, and public campaigns, could be part of the postal services' broader communications, they do not capture the primary focus of the Bulletin. The emphasis is on policies, which provide the foundation for the other aspects to function effectively.
