A mail delivery alert system includes a mailbox housing that encloses an interior space that defines an open front. A door is pivotally coupled to the housing and is movable between open and closed configurations relative to the open front. A first sensor is positioned in the housing so as to detect an opening of the door and a second sensor is positioned so as to detect the presence of an article, such as mail, in the open space of the housing. The system includes a transmitter and a processor. The processor includes programming for actuating the transmitter to transmit an alert signal through the air upon the first sensor detecting an opening of the door and the second sensor detecting the presence of an article in the open space of the housing. The system includes a receiver remote from the housing for receiving the alert signal.
