Another great information you can put in your voicemail messages is to inform your prospects when you can reach out to them say the next morning or mid-afternoon and more so that they can be aware of when they can expect a call from you.
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.

Recording your professional voicemail greeting can sometimes cause apprehension, especially if you have never done so before. You may find it helpful to go to a very private location when you are ready to record, and this can help ensure there is no background noise when you are finished. Take a few minutes to review the list you made earlier, and rehearse the greeting a few times if you are extremely nervous. While you are rehearsing, make sure your speech flows smoothly and you do not use filler words like "uh" or "um". Is Amazon actually giving you the best price?
