For those with voicemail greetings that get changed about as often as a new president is elected, know that this is doing a serious disservice to the caller-recipient relationship. It signals to callers that the business is anything but an authority, most likely not very detail oriented, and has questionable overall credibility and competency. Those aren’t traits that any business wants to associate itself.
We surround ourselves with positive people and influences, and we live life with a strength that’s forged by the conviction of our beliefs, not the strong pull of our society towards the lowest common denominator.

Your voicemail may be able to pick up even the slightest noise in the surrounding. So, if you can wait until it’s quiet to record your voicemail messages, then you should. If you’re working in an office where there are many people in the same room as you are, at least give them the notification that you’re recording a voicemail message, so everyone in the room is aware of the need to be quiet.
Your listeners may not be able to see your happy and friendly face, but they’ll hear the cheeriness in your voice. This makes a significant impact in creating rapport with your listeners. Sounding professional in your business voicemails should never be at the expense of being friendly. After all, no one would ever want to listen to someone on the phone who sounds rushed or is dry and grumpy.
