Setting up your voicemail with these tips, shouldn’t take more than 5 minutes out of your day. Just put together a quick script that includes more information included in the list above then you currently have. Don’t worry about it being perfect; having the information available for customers is better than not!
Speak clearly. Don't mumble; speak too fast or too slow. You want people to understand your greeting. The way you communicate with people through your greeting is an example of how you communicate with people in the real world.

Combine with a Business Intro Message to provide menu options and assist in telephone navigation. As opposed to the passive nature of Messages On Hold, voice prompts are interactive. They are designed to bring out a physical reaction from the caller, a call to action. And because voice prompts are directive, it’s important they’re concise, well written, and recorded by a professional voice artist.
The simple truth is that you need to be more aware of what you’re leaving for other people to hear. Sure, this doesn’t always register as a priority for users, but it’s never too late to reassess your greeting. a. Reading/Speaking in the Imperfect Tone: Tone is absolutely everything. Users don’t want to come off as being too nice, as it sounds insincere, or being too terse, as it can be interpreted as being rude. That being said, striking the right balance is absolutely essential. Your greeting exists as its own entity, and therefore, it should NOT rely on callers’ familiarity with you. Instead, it needs to appeal to the masses. As such, your inflection, i.e. the way you state your name and directions, needs to be both welcoming and firm. b. Injecting Humor & Insincerity: While humor/light heartedness can be welcoming, it can also convey a sense of informality, insincerity, and ultimately unprofessionalism. Why, because you’re not there to lend your humor or to contextualize. Instead, you’re assuming the caller has a working knowledge of your personality to ground the message. Though this might not sound like it’s all that terrible—it can be detrimental. As stated above, one should NEVER rely on a caller’s familiarity with you. Instead, aim to appeal to the masses. Humor is ultimately subjective, meaning not everyone has the same tastes; therefore, someone is bound to be turned off by a quirky or off-color remark. While implementing a light-hearted or even tongue and cheek tone can work, it’s just a really bad idea.
