Improving the Mail Service Update Process

In response to recommendations from a Mailers Technical Advisory Council (MTAC) workgroup, the Postal Service is improving our Mail Service Update (MSU) process.

These improvements include expanding and standardizing information to provide mailers with timely updates on occurrences such as service disruptions due to weather, diversion of drop shipments and scheduled resumption of operations.

The updates are made in real time, and in many cases, frequently.

To receive MSU notifications via email whenever we make a change, please click on Mail Service Update or send an email to mailserviceupdate@usps.gov. Be sure to put “Subscribe” in the subject line. Each notification you receive will provide you with an opt-out option.

Even if you don’t want to receive the “pushed” email notifications, you can always check http://www.usps.com/communications/news/serviceupdates.htm (accessible through usps.com or RIBBS^®) for up-to-date, downloadable information.
