When you send email to someone, you are addressing another
person directly as if you were calling them on the phone or
writing them a letter.
Thus the following should always be done when sending email:
Always include a short subject field in
your mail message
Always include a salutation to the person to whom you are
writing (i.e. Hi Joe, or Dear Frank, or
Sue, or Dear Mx. Yin, etc.)
Always nicely space the text of your message
Never type more than about 70 characters per line
of message text before hitting a return
Always sign your name after the text of
your email message
Always include relevant information after your name
(phone number, email address, postal address,
organization, etc.)
This information would depend on
how well you know the person, or what they might need
to know to contact you, etc.
BEFORE you send your message, read over your
message, correct spelling and/or grammar, and
make sure that your message
clearly specifies
what you are talking aboutand
provides all necessary information
that the person will need in order to
sensibly respond to you
