Are social media and mobile apps causing e-mail usage to rise or decline?

What do you think?

Take a guess before reading the information below.

(Note: A special thanks to Morgan Stewart, director of research and strategy for ExactTarget (, for this data).

44% of people who used social networks more also use email more often, which suggests that social media is driving some increase in email use.

However, the finding that the 22% of people who never use social networks report also using email more, compared with only 7% who are using email less, suggests that the increase in email use is attributable to more than simply social media.

What other factors would you say are influencing this?
