Abstract: A mail delivered indicator apparatus and method is provided which includes a toggle bolt wing, a 90 degree stop element, and a relatively thin, planar stem or mast including a design element. One side of the toggle bolt wing is attached to the upper surface of a mailbox. The stem is attached to the other side of the toggle bolt wing. The 90 degree stop element is received by or attached to the toggle bolt wing to stop the stem from further movement when it reaches a substantially vertical position. An offset stem or mast includes a slight offset to allow the toggle bolt wing to be attached to the center of the upper surface of the mailbox and at the same time ensure that the free end of the stem bypasses the door latch attached to the upper forward surface of the mailbox. In a particular example, a stem having an offset and a design element integral therewith is reversible in order to accommodate the location of a standard outgoing mail signal flag mounted on either the right or left hand side of the mailbox.
