Though e-mail is now a fixture of modern communication, it also poses a serious problem: spam (or unsolicited commercial e-mail). This study examines people's perceptions and frustrations on the subject lines of spam e-mails (junk e-mails). Using the Q-sort technique as a measurement tool, forty participants from Greenlee School of Journalism and Communication at Iowa State University presented their preferences of advertising e-mail subject lines and levels of frustration on spam e-mail subject lines. The analysis indicated that e-mail messages of travel promotional information or novice products, such as digital camera, could intrigue most participants to open. Another finding was that participants' levels of frustration caused by receiving spam e-mail messages were not high while comparing to other daily frustration events. The results also suggested that pornographic language was the most recognizable characteristic of spam and made participants feel extremely frustrated.
