Hi, you have reached (names) voicemail. If you want money or to sell us something, we a) gave at the office, b) already have it, or c) don’t want it. If you are a friend, trying to give us money or just want to talk, then leave a message or try my cell phone number. I don’t know who you are, and I don’t know what you want.
We actually know a top insurance sales guy who did a sales motivational message every day just like this, and people used to call just to listen to his thoughts.

Or say that your brand is on a holiday, you can’t miss out on leads because you know their value on your business.
Friends and colleagues speak to each using first names only. So do people of authority. They do not call each other and leave voicemail messages asking for Mister, Miss, or Mrs. Therefore, when you call a person you want to do business with and you leave a voicemail message, refer to them by their first name only. Don't say mister, miss, or misses. Don't say their last name. Begin your voicemail message by saying only "hi/hello" followed by the person's first name. Or, you can even forget the "hi/hello" and just say the person's first name. That is how you show confidence and authority and separate yourself from weak salespeople.
