This article aims to provide an overview of the various uses for e-mail in foreign language learning. It describes the advantages that have been referred to in the literature about the use of e-mail in foreign language learning contexts and provides an overview of the different types of contexts and possibilities for communicative interaction through e-mail that have been attempted in and outside of the foreign language classroom and then discussed in the literature. The pedagogical benefits of e-mail include the following: extending language learning time and place; providing a context for real-world communication and authentic interaction; extending topics beyond classroom-based ones; promoting student-centered language learning; encouraging equal opportunity participation; and connecting speakers quickly and cheaply. Suggestions for incorporating e-mail into foreign language classes include: group e-mail exchanges; intraclass and interclass e-mail interaction; e-mailing independent groups outside of one's class; various forms of one-on-one e-mail interaction, such as e-mail between the teacher and the foreign language learner, between two individual foreign language learners; and structured and unstructured exchanges. The most important benefit of e-mail exchanges is its potential to offer learners opportunities for much more valuable communicative interaction in the target language than was ever possible in the traditional foreign language classroom.
