This study investigates the effects of e-CRM on consumer satisfaction and repurchase intention depending on gender differences. A total of 400 surveys were distributed and 382 were used in the analysis. Surveys were conducted on the respondents who had purchased apparel from an internet website within six months. A factor analysis, reliability test, and path analysis were used in the study to analyze the data. After the factor analysis, 6 factors were found under e-CRM activities; benefit and advice, customer contact, service, post-purchase management, assistance with the purchase, and discriminative treatment. The results of this study showed that for male consumers, service and post-purchase management had a positive effect on consumer satisfaction that in turn had a positive effect on repurchase intention. However, for female consumers, benefit and advice, customer contact, service, and discriminative treatment had a positive effect on consumer satisfaction that in turn had a positive effect on repurchase intention. The results also showed that post-purchase management had a positive direct effect on repurchase intention for both genders.
