Despite all the fatalistic predictions about e-mail, the figures provided by Radicati Group show an increasing volume, both in the number of accounts opened and in the volume of activity. In 2012, there were 3.3 billion accounts, and by 2016 the figure is expected to reach 4.3 billion worldwide, with annual growth of 6% over the next four years.

About half of current users are in the Asia-Pacific region. Europe represents 22% of all users, North America 14%, and the remaining 14% comes from the rest of the regions.

Within this huge volume, corporate accounts accounted for 25% of the total in 2012, a figure that will grow to 27% in 2016. In terms of traffic generated, most come from the business sector. In 2012, the number of business emails sent or received daily reached 89 billion, a figure that will grow 13% per year over the next 4 years, to reach 143 billion messages a day in 2016.

And not only does the traffic and the number of accounts grow, there is also a change in how you access those emails. Every day, consumers access their email accounts using mobile devices, growing at a double rate through desktop devices. Since August 2012, access to mail through tablets or smartphones has grown 114% and 83% respectively, compared to 40% growth in PC, according to SendGrid data.

According to data from Radicati, the number of mobile e-mail users reached 730 million people worldwide, which already represents 34% of the global users.

But in spite of this fact that more and more users with mobile access are increasingly available, eConsultancy found last year that 39% of companies do not yet have a clear strategy for mobile mail. They are still sending to the mobile devices a mails optimized for the PC and not for smartphones, which takes to the users to enjoy an inadequate experience that, in a lot of possibilities, will take that the mail finishes in the bin before being read Treated as spam.
