Many managers admit to us that once they identify a familiar caller, they delete the rest of the message. “Why waste time listening to someone babble when I have to call them back anyway?” is a typical explanation. This should encourage you to leave short, sweet voice mails. Don’t volunteer extraneous details or repeat yourself. Just state your name and phone number. If you’re calling someone you don’t know, then insert a one-or two-sentence reason for the call and hang up.
