I guess the creators of mail art were thinking about how to exchange art and exhibit without having to participate of the art market scene. The creation of the Internet made the transfer of images instantaneous, but the materiality and the intimacy of the mail art object was lost if sent through e-mail. Real mail continues to be necessary to exchange art even for the art market. E-mail did not eliminated mail art, it only eliminated most intimate correspondence like love and friendship letters. It even threatens with eliminating calligraphy. Those of us who still love the snail mail continues to produce letters and postcards and exchange it with others who love the same thing. We call ourself mail artists.
