Contemporary developments in technology provide opportunities for qualitative researchers to enhance their modes of collecting rich data for analysis. In this article we explore the utility and impact of using email as a means of collecting data in the form of semi-structured interviews. We investigate what participants think about email interviews, and how they view the relationship between email interviews and online pedagogies. We illustrate our discussion with reference to a recent research project carried out using email interviews with professional colleagues, including analyses of the respondents' own insights about the methodology. We conclude that email interviews provide a useful medium to explore the experiences of an international group of participants, including some for whom English is not their first language. Further, the method enables respondents to participate in the process of collaborative knowledge building as co-researchers, by reflecting on and analysing their own responses in the email interviews.
