Among millennials, the inbox might not actually be the first place to most effectively reach certain travellers. The plugged-in generation audience of millennials seem to welcome direct mail more so than emails. They have grown up with technology versus other generations who were thrown into technology. Therefore, receiving a postcard or piece of direct mail - albeit more expensive sometimes - tends to actually be welcomed. Across industries, questions persist, with analysis over the past decade showing that a significant percentage of millennials do use the Internet to send and receive email, at least occasionally. Furthermore, as notable in the above chart, there is no statistically significant difference between millennials, Gen X and Baby Boomer respondents. All were between 54% and 57% likely to have sent or received an email within the past 24 hours. Whatever the incidence of their interaction with electronic messages, the responses of millennials to email marketing are likely to be product specific.
