Fan mail may be in the form of letters, cards, artworks, gifts, and so on; depending on the recipient, it may also be possible to send fan mail via E-mail. People send to athletes, actors, artists, singers, bands, and coaches of teams. It commonly takes three to four month for a response, depending on how famous the person is. If they are really famous and get too much fan mail they may not reply.
Etiquette
Since a major celebrity may receive thousands of pieces of fan mail every day, it is usually impossible for him/her to reply to or read them all; his/her manager often has the duty of canvassing the incoming mail. Normally fan mail should be sent to the office of the celebrity's management. Some celebrities may also charge a small fee for a signed photo.
