4. Suggest More Recipients

Suggest More Recipients will present you with a list of extra people you might want to include every time you're sending a new message. It bases its suggestions on which people you contact most often. I guess if you randomly like adding people onto recipient lists for no apparent reason, this might be for you. Otherwise, it'll just be an added annoyance on your screen.

5. Random Signature

Presumably voted in its high school yearbook as "least likely to succeed," appends a random quote onto the end of every e-mail you send. Unless you enjoy including proverbs you didn't even select at the end of every message -- which I'm sure is something your friends and colleagues adore about as much as the 50 "inspirational" e-mails you forward them every week -- you may want to steer clear of this one.
