The bottom line is that a business’s situation is likely to change often and rapidly, each of which need a unique and applicable voicemail greeting to cover the circumstances and timeline. For example, callers shouldn’t reach a business-as-usual voicemail, and therefore expect a return call within the business day, if the subject they’re calling is out on vacation for two weeks. Such a lack of communication is a recipe to lose that caller’s trust and tarnish the brand’s reputation.
Leaving a voicemail can still be a good way to grab the attention of a potential new customer. However, when it comes to leaving a voicemail, you only have a few seconds to actually grab the listener's attention. Most salespeople screw this up by leaving too much information and making themselves sound like a salesperson, which is the kiss of death when leaving a voicemail.

7.) End on a high note! You don’t necessarily need to say “Goodbye” at the end of a voicemail, because you didn’t really talk to anyone. Instead, try something like, “Look forward to chatting with you!” Use the word “with” instead of “to.” It sounds less like the person is going to receive a parental or boss “talking to” and more like two people who are eager to connect with one another on the phone. It’s a subtle difference, yet it’s a gracious one!
Dave is out. Jane is out. Rover is out. This is their answering machine. I am in. The beep is in. At the sound of the beep leave your name. At the sound of the beep leave your message.
