Mail-Art is an international network of artists, who communicate by sending works of art to each other. Finding its roots in the Fluxus and Dada movement, mail art is a child of the 60's. The idea then as it is now is to create and make possible the direct exchange of art between artists on a global scale, completely bypassing the established art channels, such as galleries and museums.

Mail-art works like this: An artist or group of artists come up with a concept for a project and send out invitations via the network inviting the participation of other artists. There are no limitations regarding the material and techniques. The only steadfast rules being the end result must fit the original theme and it must be possible to mail.

Today, thanks to the internet, webpages and e-mail, the options for mail-art have increased and the exposure of the projects has become easier, however the basic definition of mail-art still remains somewhat difficult.

Mail-Art itself is considered an art form and many well-known artists such as Yoko Ono or Christo have participated. The analogue network today consist of approximately 20,000 artists.

In regards to Mail-Art Matt Ferando writes:
Some take a conceptual view of mail-art. Chuck Welch, a prolific mail artist known as "The Crackerjack Kid" and editor of Eternal Network: A Mail Art Anthology, contends that "information, communication aesthetics, and cultural motivation determine whether an artwork or artist fit within the complex Mail Art and Networking movements." Conversely, others like Kornelia Röder, the co-editor of East Europe in International Network, posit the movement in political terms. "Mail art does not mean the personal correspondence between two persons," writes, Röder, but rather is "the communication with art to projects arranged concretely which are often motivated by the socio-political context." Guy Bleus, a mail artist, theorist, and collector whose Administration Centre 42.292 is regarded widely as the most complete archive of mail art in the world, calls mail art "an 'encounter-place' for artists of different social classes, different cultures, different ages, different ideologies."
