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.
