Which service provides insurance with delivery tracking?

Priority Mail Express is the service that provides insurance with delivery tracking. This service offers a high level of reliability and speed, ensuring that customers can send packages overnight to most U.S. locations. In addition to the fast delivery, it includes tracking capabilities that allow both the sender and recipient to monitor the package's journey in real-time. Moreover, Priority Mail Express comes with optional insurance, which means that the package can be protected against loss or damage, providing peace of mind to those sending valuable items.

While other services like Priority Mail also offer tracking and some insurance options, Priority Mail Express stands out due to its guarantees and features specifically designed for time-sensitive shipments. This makes it the most appropriate choice when seeking both delivery tracking and insurance in one service.
