Banning internal email -- is it a stupid idea, or a necessary thing to do?

In late 2011, the IT services firm Atos and its CEO Thierry Breto announced that they planned to ban internal email within two years, calling the volume of internal emails "unsustainable."

The announcement created a lot of reactions and was met with quite a lot of skepticism. I am sure quite a few people got a good laugh from it. Why ban email? Isn’t that a bit too radical, almost crazy? That’s typical French! Working without email… woah-haha!

Multiple studies indicate that the average corporate employee spends around 25-30 percent of their workday on email related tasks. By comparison we spend 14 percent of our time, or just 6.4 hours per week, on "communicating and collaborating internally."

It wouldn’t be an issue if we were getting work done during all that time, but fact is that a large portion of that time is spent simply on managing -- organizing, archiving, deleting -- the emails that we receive. In addition, a large part of the emails we receive have nothing to do with work.

According to a study by Mimecast from 2012, around 7 percent of the emails we receive at work is spam or junk mail, and another 11 percent is personal or non-work-related. 63 percent of the emails are used for employee-to-employee communication.

Information or Distraction


Spending 25 to 30 percent of our workday on email-related tasks perhaps wouldn’t be such a big problem if you did it all in one chunk, say during the first 2.5 hours of your workday. Although you may be an exception, that’s not how most people manage their emails. That’s not how email works.

You get an email when the sender decides to send it to you, whether you want it or not, and whether it suits your work to read it or not. With email, anyone who has access to your email address can point and shoot whatever message they want at you. Potentially anything can end up in your inbox. Ubiquitous access to the most versatile communication tool makes it very easy to bombard people with information.

And this bombardment goes on, continuously interrupting you from completing the task at hand. For example, a study by Priority Management found that the average manager typically get’s interrupted every eight minutes. After each interruption it takes some time to return to the task that was interrupted, especially when it comes to serious mental tasks, such as programming or writing.

When you have been interrupted you typically wander off to reply to other messages or browse the web. It is likely that you spend about two hours per day on being interrupted and trying to refocus (pdf). That doesn’t leave much time over for being productive, does it?
