Based on a variety of methods such as interviews, questionnaires, and corpus-based research, the book investigates the impact of electronic mail on several aspects of organizational behavior. These include, among other fields, e-mail marketing, customer relationship management, and hierarchical structures. Furthermore, the thesis presents research findings which show that diligence – or the lack thereof – can still win – or lose – contracts even in the age of electronic communication. The study deals exclusively with native-speaker communication to exclude any distortions deriving from non-native language problems and inaccuracies. Finally, mainstream e-mail guidelines are examined and compared to the way in which they are handled and perceived in real business life.
