Quote your previous message if your are referring to a previously sent email.  The person receiving your message may not remember what they sent to you.

Do not use pronouns in the first sentence or two..  Your reader can't hear or see you so they may not know what you mean by "it", "they", or "he".

Do not use fancy text.  Some computers may only be able to read plain text. Italics, bold, and color changes may show up with "<" and ">"  around these words instead of the look you wanted.
You might send this:   I would like to know why you sent me that message.
Could be received like this:  I would like to know <why> you sent me that <message>.

Use shorter sentences and paragraphs.  Sometimes long paragraphs and sentences are harder to read.

Web links may be included in your message, just be sure to write the URL with http:// before it.  This will make a live link.  It may be easier to copy and paste a link to be sure it is exact.

Use capital letters (NO), asterisks (*), and smileys :-) to add emotion to your text.  Remember, your audience cannot hear or see you, and those are helpful when communicating.

Use grammar and spell checkers.  It is important that your message make sense, and good spelling shows you care enough to do your best.

Your signature is included after your message.  Sometimes the name at the From:  line doesn't match your name (you may be using your parent's account-with permission of course!)  Do not include your telephone number without your parent's specific permission.

See you soon,
Tommy Smith
