That’s the simple structure of a voicemail greeting. Overall, your greeting should be professional, but the wording can vary depending on the situation. Check out a sample below.
Your prospects are under the impression that a brand will be always available to cater to them, now for some circumstances, a few brands might not be able to serve their prospects 24/7 which is why creating a voicemail message becomes useful.

In order to ensure customer satisfaction, it is not only important how a business records their outgoing voicemail greeting, but also how they respond to incoming messages. It has been reported that most individuals do not mind leaving voicemail messages, but they can often become frustrated and disheartened when a business does not return their call in a timely manner or ignores the voicemail altogether.
The phone you use to record your greeting – and your surrounding – can turn your carefully scripted greeting into an unprofessional mess. Background noise is terribly distracting, so choose a quiet room or parked car to make your call. Landlines, or a “wi-fi enabled” cellphone call, can provide much better connection quality than a standard cellphone. If you must use a cell phone, be sure to use a high-quality headset for the best clarity.
