Email Addresses
•
An email address has two parts:

The user_id is chosen by the user or assigned by the
Internet Service Provider (ISP)
2. The user’s mail server’s domain name.
The two parts are separated by a “@”.
My email address for example is:
[email protected]

Creating an email address list
• Address lists allow users
to send email to the same
list of people on a regular
basis.

systems limit lists to no
more than 25 users.

Netiquette
netiquette -- rules of behavior for persons using the
Web and other Internet communications. These
rules are commonsense manners that prevent the
user from misusing resources, or harming the
author, or others.
Netiquette in Internet
communications.
• Golden Rule – don’t send anything that you would not want your
mother to read.
• The use of bcc, mail forwarding, etc. allows email to have a life of
its own. You don’t own it and your boss and many others may
read it. In most cases you Do Not have a right to privacy (current
law on this is subject to change)
• Corporations are learning that their email archives can be
detrimental in court cases.
• Just because you delete it does not mean it is gone. Government
and corporations have requirements for retention and archiving
email as legal documents.
• Sexual harassment, cyberstalking, and child porn can get you fired
and/or arrested.

7.
Ignoring – not reading email in a timely fashion can be grounds
for dismissal in some corp.
Lying – I didn’t receive it. Email leaves a trail.
Presuming -- Sending email without a follow-up phone call on
critical matters.
Waffling – Be succinct.
Blitzing – Sending email to busy people who are not relevant is
spam.
Sloppiness – lazy, incorrect grammar, misspellings, etc. create a
negative impression.
Tactlessness – Email can be easily misconstrued. Puns, irony,
etc. are lost in text, use emoticons and care, reread before
sending, don’t use all caps, and most important never send an
email written when you are angry or upset (if in doubt have a
trusted friend read it and wait, if possible, to reconsider it when
you are in a cooler state of mind).

disappointed
