Your business depends on customer engagement, and voicemail messages are a large part of that engagement. A voicemail is nothing more than a digital recording system, where messages are stored for you to retrieve later. Voicemail allows you to be able to connect with customers while you are away or during your off-hours, where they can drop off a message while you are gone. A voicemail greeting, on the other hand, refers to the message that your callers hear upon answering the phone.
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.
