There was an interesting article in eMarketer about frequency of reading email that I would like to share with you.
According to a AOL-sponsored survey by Beta Research Corporation nearly one-quarter of Internet users surveyed in June 2008 said they were most likely to check their email upon waking. But more than one-third said they checked throughout the day and the rest of respondents said they checked at various times, including throughout the night.
More than seven out of 10 employed respondents also said they checked their personal e-mail at work—and nearly one-third said they did so more than three times a day.
Nearly 70% of respondents said they had multiple e-mail accounts.
