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.
When you know something to be true, when you have an opinion that needs to be shared, be more assertive and powerful in your word choices. Here are 3 simple ways you can do that.

Here’s the thing: no matter how perfectly-crafted your sales voicemail is, plenty of people are still going to ignore it or stop listening midway through. That’s actually okay, though. We already know that other types of messaging, like emails, get a higher response rate. But where voice messages win is in quality – when you do get a response, that means the person has a very high level of interest.
"Wherever we're talking to them, we're hearing the same things, which is: When it comes to voice mail, they're just over it," says Jane Buckingham, a trend analyst at Trendera.
