The main point that we want to drive home with this article is that you shouldn’t overthink your business voicemail greeting. Just keep it short, and state the relevant information.
Whether it’s an out-of-stock product, a canceled event, or social media snafu, there are times when your business may see an influx of frustrated callers. While it is important to address their concerns head-on, you may not be able to answer each call as it’s received. Make sure you use best practices for dealing with angry customers, and that your voicemail greeting sets the appropriate tone. Avoid defensive language, validate their concerns, and keep them informed as to how you are handling the situation.

Your voicemail should be very specific. It should be short and urgent. Use word's like "need", "should", "must" , or "have to" to create a sense of urgency. For example, say something like, "We need to discuss..." or "We should talk about..."
Business voicemail greetings are rarely thought of as a prime way to connect with customers. But just because you're not available doesn't mean you can't make a positive impression on your customers when they reach your voicemail box.
