If you believe that transparency in communications significantly promotes efficiency and effectiveness in your company, if you feel responsible for the clarity of your e-mails, you will not commit any of the sins described above any longer. Convince your boss and your management colleagues by reacting (moderately) to your colleagues’ sins – above all with I-statements about the self-revelation of the sender and what his/her communication behavior means for the appreciation of the relationship. Where your employees are concerned, it is certainly possible for you to react to sins with a clear statement – but please, not until the two of you are alone. In other words, not by e-mail! ­Convince the people in charge of training programs in your company that e-mail communication really is a topic worthy of a training program for employees, perhaps even within the framework of ­value discussions. Possibly you can even gain the support of your CEO as a powerful sponsor who gives the topic the necessary weight from the very top level. But continue to grind your teeth and bear with it when your customers commit all of the listed sins – unless you are the communications trainer who is paid for it.
