You have reached (Your Name) at (Your Business). I was unable to take your call, but if you leave a brief message I’ll call you back as soon as possible.
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.

5. Holiday Voicemail Greetings. Happy [X holiday]! You've reached [your name] at [X company]. I am currently out of the office, but please leave me your name, phone number, and the reason you are calling, and I’ll return your call after the holidays.
Responding to voicemails is time-consuming. Fortunately, with the right greeting, you might be able to save yourself some hassle. If you don’t have an auto attendant, you can give callers the information they are looking for with your voicemail greeting. Of course, this means that your greeting may be a little lengthy, but that can work in your favor as callers will only stay on the line to leave a message if they still need assistance.
