Updated September 14th: We’ll have an update very soon with a fresh look, full support for macOS 27 and macOS 26, and some other improvements.
Starting with Deliveries 9.6.2 and service update 261 or later, U.S. Postal Service shipments are updated through deliveries.app. This is a necessary change due to changes with the U.S. Postal Service tracking system. Learn more about this change.
Deliveries 9.6.3 or later fixes some issues with USPS. Note: UPS and FedEx tracking information is no longer available in the app. See the latest service updates.
