If you find it intimidating to communicate with someone, the chances are your message will not be very effective. It may not be appropriate without getting your message funneled through the regular channels. The simplicity of this form of mass communication is not evident in any other communication medium. Through the Internet, one can also subscribe to various mailing lists and receive mailings on a regular basis on many different subjects. The Telephone is certainly the most interactive of the communication media.
Email is certainly more interactive than any of the written communication media.
This is possible through other written communication media, such as regular mail and fax, but is certainly much more cumbersome and inefficient. A copy of all messages that you send via Email can be stored in your sent-mail folder, making it much easier to track your outbound correspondence. Many people find that stored Email messages make an excellent journal. The major drawback to using Email as a communication medium is that the sender and receiver must both have Email access. All forms of communication have this problem.
