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.

The above greeting is a professional voicemail script used by many growing and established businesses. It delivers the message quickly and efficiently, without wasting the caller’s time.
Your voicemail is important. Keep in mind, this is essentially one of the first impressions the hiring manager will have from you. You need to make sure your voicemail is as professional as possible. Whether you are trying to be funny, trying to show off your singing abilities or shouting in the car with the windows down, chances are the hiring manager won’t be impressed. Go into a quiet room and record a simple, “Hi, you’ve reached Kim Costa. I’m sorry I missed your call, but if you please leave your name, number and a brief message I will get back to you as soon as I can. Thanks!” You really can’t go wrong with this. Trust me when I say that hiring managers probably don’t want to hear your high school’s fight song.
