It might be a short voicemail message that you’re recording, but you do want to make sure you hit all the bullet points. It also helps to speak eloquently over the phone and that works better when you are prepared with what you’re about to say. You are trying to sell yourself in this message so put your best foot forward. If you practice and write down what you’re going to say, you can get rid of all the awkward pauses, ums, and stumbling over words.
12. "Hi, you've reached [company]. We're available by phone from [hour] to [hour] [time zone] Monday through Friday [optional: and from hour to hour on the weekends]. You can also contact us by going to our website, [URL], and live-chatting or emailing us. If you'd like us to call you back, please leave your name and number after the tone."

I’d be willing to bet that a lot of Maid businesses really don’t think about their voicemail recording more than a handful of times over the course of the lives of their business.
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.
