Content, Tone, and Correctness

E-mails are not similar as a telephone call, it produces a permanent record so be careful about writing.  To write an e-mail, there are some points to consider like write only informative data and be concise. No one wants to read long e-mails so try to avoid long e-mails. Organise all the ideas tightly and think carefully about what to say and how to say. E-mails create a permanent record so do not send sensitive, inflammatory, or potentially embarrassing messages. Do not use e-mails to give bad news to someone as it will hurt them more. For example, it's improper to fire a person by using e-mail. It is also not a good channel for dealing with conflict. People sometimes make mistakes in spelling and send sloppy e-mail which create problems for readers. Correctness and Tone are very important to write a message. Message words and writing style affect the reader so avoid negative and domineering words. Humour in e-mail messages can easily be misunderstood so avoid it
