Mail art, also known as postal art or correspondence art, is a form of art that involves sending works through the postal system. This medium has seen a resurgence in recent years as artists rediscover the tactile and personal experience of creating and sending physical objects. Some synonyms for mail art include postcard art, letter art, and snail mail art. Whatever the name, the art form is characterized by its accessibility and lack of commercialism. Anyone can create and participate in the exchange of mail art, making it a truly democratic and inclusive form of artistic expression.
