5.1.7 Email etiquette

3. Correct communication via e-mail

• e-mails should only be used for simple matters.
  For more complex tasks, additional explanations should be given by telephone.
• choose a meaningful and topic-related subject line.
  
• always write e-mails briefly and to the point. Explain what you expect from the recipient and by when these expectations should be fulfilled.
• since many people sort their emails by projects or tasks in the inbox, you should write a separate email for each topic. This makes it easier to find the mails later on.
  
• E-mails are also business letters and should be written formally. 
  Exceptions apply only in the case of very personal contact.
• avoid long CC lists. This looks unprofessional and often unnecessarily clutters up mailboxes.
