How to write email:

Important Points to Remember

Email is much less formal than a written letter. Emails are usually short and concise.
If you are writing to someone you don't know, a simple "Hello" is adequate. Using a salutation such as "Dear Mr Smith," is too formal.
When writing to someone you know well, feel free to write as if you are speaking to the person.
Use abbreviated verb forms (He's, We're, He'd, etc.)
Include a telephone number to the signature of the email. This will give the recipient the chance to telephone if necessary.
It is not necessary to include your email address as the recipient can just reply to the email.
When replying eliminate all the information that is not necessary. Only leave the sections of text that are related to your reply. This will save your reader time when reading your email.
