What is U-Mail? U-Mail is a protective mailbox with a built-in locker, designed to securely accept and store packages and letters. Mail theft is an ever-present problem, but requiring deliveries to come to porches and houses can be inefficient and potentially risky for drivers. U-Mail is a steel locker with a mailbox attachment and keypad controls, for a convenient and secure way to hold packages and mail deliveries of all kinds. U-Mail is opened and closed via a secret passcode that can be shared with trusted delivery drivers to facilitate safe package drop-offs. U-Mail features a hydraulic arm to assist in lifting the heavy-duty locker lid, and an easy-to-reach mail slot which routes letters and smaller mail pieces directly into a secure compartment. The U-Mail locker can also be discreetly installed underground, while the modular mailbox section can be matched to almost any décor, for seamless integration into the landscape.
