Don’t be too hard on yourself. Chances are, that voicemail that you’ve recorded and deleted thirty times has been just fine. Your main goal is not to get in the way of the caller leaving a message, which is exactly what can happen if you overthink it or drone on too long.
A professional voicemail greeting is a recorded message that welcomes callers to your business when no one is available to pick up the call. For a polished call experience, the greeting should reflect who the client is calling – whether a general business number, department, team, or individual – and when the customer can expect the call to be returned.

Feel free to add a personal touch to make your voicemail message fun and interesting. Clients will feel reassured when they know their messages have been received and you will get back to them.
