    These statistics are amazing. Email is really on the rise – and it’s fast.

    With 730 million business email mailboxes, 43 business email sent, and 25% of work day – this just proves that email has become one of the corporate world’s main forms of communication (If not the top one).

    I’m just surprised about the “1 in 284 emails contain malware” statistic. I think it’s a little higher. 10 out of 284 perhaps?

    Amazing.
    All these statistics and percentages just blow my mind, it’s all so cool!
    And to think that one botnet could send out 44 billion email messages, and the culprit was never caught (atleast, not that I know of, I did a bit of googling)
