4. Do not ’scream’ in your email. No capitals all the way (IT IS VERY HARD TO READ WORDS IN ALL CAPS), no exclamation marks in succession (like this !!!!!), no crazy typefaces in hot pink and hot green unless you are emailing a friend of yours whom I presume knows you well.

5. When you are emailing an attachment, please tell the recipient how big the attachment is and what it is, unless it is some surprise. Don’t know how to find out the attachment’s size? Just right-click on the file you’re sending and scroll down to “Properties”. Click that and you will see how big your file is.

6. If you are emailing a number of people and they don’t know each other, please put them under BCC (which stands for Blind Carbon Copy). It means they will not see each other’s email addresses when they open your email. This also applies when you are forwarding a joke to friends. Erase the rest of the other people’s email addresses and just forward the crux of the email which is the joke itself. Your recipients don’t need to see the long list of email addresses. Note: unethical companies mine these email addresses for spamming when everyone’s email address is exposed in forwarded emails.

7. When you are posting a reply to a mailing list group such as YahooGroups, please erase the rest of the old message if you don’t want to annoy others who have read these messages before. Just get to the point.
