This study attempts to conduct a pragmatic analysis on a business email discourse. A pragma-dialogue approach was adopted to investigate the dialogic nature of interaction between e-mailers of an Algerian private company and an Indian one. A corpus of 150 emails exchanged between both companies is compiled to be pragmatically analyzed by focusing on speech acts and conversation, politeness, impoliteness, questions, promises, conversational implicature, reference, presupposition in addition to cultural models and norms. The study suggests recommendations to focus on promoting the pragmatic discourse analysis of more spoken and written business texts so as to ameliorate their acceptability and efficiency.
