The present invention relates to a three-dimensional smart messenger envelope comprising a main body for accepting contents; and a cover integrated with the main body to cover an opening of the main body. An overlapping part in which the main body and the cover overlap each other is bonded to the main body and the cover. A dotted line is formed on the overlapping part to allow the opening to be open. An advertisement unit is attached to the inner side of the overlapping part positioned on the main body side to three-dimensionally protrude towards the front of a receiver from the inner side of the cover when the cover is open. |
