The basic rule of thumb is that callers should hear one of two things when they first connect with your voicemail — either an apology for not being able to answer the call or a “thank you” for having called. You can do both if you prefer, but keep it short and to the point.
In short, more often than not, voicemail greetings feel bleak and boring to callers. If you’re a business, boredom is an awful way to start off the conversation with potential customers. Since the attention span of a human being fluctuates around 8-10 seconds, filling them up with a standard voicemail greeting is the worst idea you can have.

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.
