The purpose of this study was to evaluate students' perceptions of faculty credibility based on email addresses. The survey was conducted at an upper division business school in Michigan where all students have completed at least two years of college courses. The survey results show that a faculty member's selection of an email address does influence the student's perception of faculty credibility. An email address that consists of a nickname reduces the student's perception of faculty credibility. The reduced creditability may have a negative impact on the faculty member as well as the college.
