Postal mail works for musicians. It worked 100 years ago and it still works today. In fact, it works even better today than ever.
Why? Because almost nobody is using it!
According to the annual survey done by the post office, in 2010, the average household only received one personal letter every seven weeks. This is "primarily driven by the adoption of the Internet as a preferred method of communication."
But that doesn't mean the Internet is the best form of communication when it comes to your music career...
Emails are quick, but they get deleted easier...if they get opened at all. And, like text messages, Facebook updates, or messages on Twitter, they're a lot more impersonal than a hand-written letter or postcard.
If you want to form quality relationships with fans, you're missing a big oppotunity by not using postal mail.
