All age cohorts of internet users (ages 12 and older) are equally likely to use email; about 90% of all internet users send or receive email. Given the many other variations in internet use among different age groups, it is notable that this basic communications tool is almost universally used. Even teens, many of whom disparage email as something for "old people," and tend to prefer instant messaging, have not completely abandoned it. Email is the most popular online activity, especially for internet users age 65 or older. However, the best place to reach someone age 70 and older is still offline. Only 26% of Americans age 70-75 and 17% of Americans age 76 or older go online, Pew Internet & American Life Project says.
