Email Etiquette

I will not go over the email basics like avoiding capital letters and bold font in official mail.
I will mention few other pointers which one needs to keep in mind when dealing with email.

1. Never delete official email. Archive them when your inbox is overloaded. Pay special attention to Sent email. You might have to fish out certain emails for future reference.
2. Always put a subject line in your emails. If you are sending the mail to any one person, do mention his/her name after the initial Hi/Hello. This shows respect towards the person whom you are sending the mail to.
3. When sending an email to a senior, use 'Hello'. To  peers, use 'Hi'.
4. Always answer official correspondence. Even if it is a simple thank you note, make sure you answer it. Not answering official email equals impoliteness.
5. Be aware of the email escalation hierarchy in your organization. Consider yourself fortunate if your company has one. Make full use of this. This ensures email truants are brought to the book and also helps to expedite office work.
6. Try to refrain using your official email address for mails from friends or promotional email.
7. Be extremely careful about the language, tone and content of your official emails. Remember - it is the written word and can be used against you.
