While missed calls aren’t ideal, you can let your caller know you’re still there for them by having a great voicemail greeting. The best business voicemail greetings let your customers (and potential customers) know why you’re not available and how they can best get in contact with your business. They are also short and to the point. You usually want to keep your greeting between 6 and 24 seconds long so callers don’t hang up halfway through.
An excellent business voicemail greeting conveys your level of professionalism and competence while also providing your callers with a glimpse into your company’s culture and level of care. As minor as it may seem, your voicemail greeting can instill confidence and trust in your callers or it can be a cause for concern.

Remember that the speed of your words can negatively impact your message as well. "If you have to rush to get a message into the amount of time allotted for a voicemail message, you’re saying too much," DeCesare advises. "Say less and slow down. You want them to feel that talking to you will make their lives less stressful. If you're frantic and mumbling on the phone, it gives them a foreshadowing of what it will be like to work with you."
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.
