As we iterated in 5 Voicemail Message Myths, when you are leaving a message for your potential leads, there are certain rules everyone should follow. Those myths have been studied and show that dismissing them result in fewer callbacks. Nonetheless, few studies have been dedicated to voicemail greetings. Therefore, you should think outside of the box and do something different. A comedic voicemail like this famous greeting from George Costanza in Seinfeld is a great example.
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.
