Decide what kind of mail to send. A vivid letter describing your feelings about the artist and his music is a suitable option. Send something that will have sentimental value to the rapper you are trying to contact such as his favorite candle, painting or sculpture. Be creative and respectful when creating your fan mail to ensure that it will be memorable and appreciated.
Locate a direct and trustworthy address. Send your fan mail to a place where you know it will be received by the artist or someone who can pass it on to him. People such as his manager, personal assistant or artist relation representative can be of assistance in getting your mail to the rapper. Outside of fan club listings, find direct addresses by contacting the artist's record label. Search online record label directories for record label contact information. Asking someone in the rapper's public relations department for direct addresses can be helpful as well.
Select a mailing method. Look for a mail carrier that offers the rates and services suitable to your personal preference. The United States Postal Service, FedEx and UPS offer mail services with competitive prices. If you are not concerned with knowing whether the rapper receives the mail you sent him or not, send it regular mail. However, if you do want to know when he receives your mail, send your fan mail "certified" or with a delivery or signature confirmation for an added fee.
