The ability to communicate effectively is a key skill for all employees. While extensive research exists regarding the characteristics of competent oral communicators, there has yet to be systematic research on the characteristics of competent electronic communicators. A new set of rules has emerged in this electronic arena, and whether those rules have transferred to the corporate environment or not remains to be seen. This paper discusses an exploratory study to identify the characteristics of email communication and the evaluations those characteristics engender. The study employs an on-line survey in which subjects are asked to read and respond to a series of four emails from the same general context. The messages are designed to be consistent with established “norms” of electronic communication, and semantic differential scales are used to assess the degree to which the different forms evoke personality evaluations in the receiver.
