50/68

Short Notes on e mail Style

DON'T SHOUT WITH ALL CAPS!

Watch addresses when replying. Make sure don't

reply to lists unless you want to. Don't count on the

email program to read your mind. The only way to

be sure is LOOK.

Resist the temptation to omit punctuation.

Use meaningful subject lines, especially when

mailing to lists or people who get large amounts of

email, like vendors.

Use stationery form letters when appropriate.

groups of people.
