Digital marketing media, e.g. internet and mobile phones, are considered powerful new opportunities to reach consumers but are dependent upon consumer responsiveness to the new media. Consumer responsiveness is a function of the perceived relevance of the marketing message and the acceptance of the medium of the message. Two empirical studies conducted in Finland showed that compared to traditional Direct Mail (DM) and commercial e-mail, the responsiveness to mobile marketing was considerably lower. The findings indicate that companies need to consider consumers' responsiveness in order to understand the marketing communication effectiveness in different traditional and new communication media.
