The growth of the Internet and the increasing application of electronic mail in many aspects of business and educational research have urged researchers to reach different individuals across geographical borders with an obvious reduction of costs and time. While the use of email surveys in educational research, as this paper mainly argues, offers significant benefits to researchers in collecting data, more awareness of ethical codes of conduct and culture of net-users should be insisted throughout the research process to enhance validity and to minimize physical or mental harm that may cause to the researched participants of different ethnic and socioeconomic backgrounds. This essay is not going to greatly discuss technological methods or concerns in the design of an email survey.
