Top 10 when NOT to email

We discuss this in class every term.

Here is one author's list:

1. To communicate bad news, complaints or criticism 2. When you are seeking information that is not simple and straight-forward 3. When you are seeking approval on something that is involved or controversial 4. When you're sending a few people complicated instructions 5. When you are asking for comments on a long document (probably attached to your proposed e-mail) 6. To request information from a group on a recurring basis 7. To convey instructions to a large number of people 8. To achieve consensus 9. To explore a subject or idea 10. To send news, interesting documents, links, policies, directory updates and other 'FYI' stuff
