Online firm Habeas released its annual study of consumer attitudes Wednesday, which showed that email remains the "primary method of communications in personal and business capacities."

The survey found that 67% of respondents prefer email to communicate online, and 65% feel that will still be the case in five years. And vis-à-vis a younger generation "aging out of email," the survey found that 65% in the 18-to-34 demo "will favor email to communicate with businesses in five years."

The research also found that there is a rise in consumer concern about email security issues--with 69% of respondents worried about "being victimized by email fraud scams," up from 62% a year ago. And perhaps giving marketers pause about advertising on mobile devices, it found that 43% of respondents were concerned about spam and virus threats on their wireless devices, up from 36% in 2007.
