This article aimed to evaluate the impact of permission marketing actions on mobile devices, both for companies and consumers. An exploratory research was applied through social networks, with questions directly related to the use, frequency and reasons for Internet purchases, use of mobile devices and, mainly, issues related to the concept of permission marketing. The results showed that most of the interviewees usually make purchases online, using mobile devices for this. It was verified that the excess of notifications and advertisements annoyed consumers, and those were seen as an invasion of their privacy.
