A smartphone application allows users to manage their incoming mail and packages, including viewing their incoming envelopes.

The U.S. Postal Service app, Informed Delivery, is free and available to smartphone users.

According to the USPS website, users can interact with their incoming mail and packages via a secure dashboard.

This includes previewing the address side of all envelopes scheduled for imminent arrival.

The app also offers notifications via email or text of packages that are on their way and provides the ability to give instructions on delivery if the user will not be home. It also can be used to reschedule missed deliveries.

With Christmas soon approaching, this could be a useful app for many to keep an eye out for Christmas gift deliveries.

Those who are interested in Informed Delivery can visit www.informeddelivery.usps.com to determine if the app is available in their ZIP code and at their address.

While some hacking experts have expressed concern about Informed Delivery, the state Attorney General office's spokesman said that there have been no complaints about the app's security.
