There are certain rules that need to be adhered to when it comes to
writing emails. Important is that you use the appropriate level of
formality for a certain message. Another thing to adhere to is that you
should not drivel, state the purpose of your email clearly and leave
out any unnecessary information. Always check your message for spelling
mistakes, correct use of punctuation and grammar. Also, remember that
you are using a computer, not talking to one. Therefore, you should say
hello at the start of your message and goodbye at the end. Be sensitive
when composing an email; remember that the person you email may not
share your values, cultural background or opinions. Also, try to reply
to an email within the same time as you would return a phone call.
Finally, never email an advert to someone unless you are good friends.
Please not that, before sending an email with jokes, you should ask
yourself if the recipient will be pleased to receive it.
