Janssen studied physics and mathematics before he became active with mail art in 1980, doing several international mail art projects. From 1994 till 2001 he conducted interviews with Fluxus and mail artists. In later years, Janssen focused on acrylic painting and individual correspondences.
Janssen was selected to publish an essay as one of eleven contemporary "New Fluxus" artists who are seen to 'inhabit the site of Fluxus, developing and interpreting the Fluxus tradition in a new way.' in a special double issue of the journal Visible Language on Fluxus.
In 1994, Janssen[1] began a series of mail-interviews. He interviewed Fluxus[2] and mail art personalities by using all the communication-forms that were available (fax, e-mail, envelope, personal meeting, telephone). The question traveled by one form and the answer could be sent back in another form. This concept resulted in a series of mail-interviews. These interviews were published in booklet-form and the complete texts are also available online.[3] In 2008, a selection of the mail-interviews were published in book form.[4]
In 1997 Janssen had a solo exhibition of his mail art work and interviews in Guy Bleus' E-Mail Art Archives (Provincial Center for Visual Arts, now Z33) in Hasselt, Belgium.[5][6]

The archive[7] contains art prints, original rubber stamps, magazines and literature.[citation needed]
