I have a confession to make: I haven’t recorded a new voicemail greeting since 2014. In the past four years, I (hopefully) have become more articulate, poised, and self-assured. But hear my voicemail recording, and you’d think I was still new to the work world, a little unsure of myself — and probably not an authority. Obviously I need toupdate it. And if you haven’t changed your voicemail greeting in over a year, you’re likely in the same boat. After all, a professional voicemail recording boosts your credibility, makes you seem more competent, and encourages whoever’s listening to it to continue the relationship. A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction. With that in mind, I’ve written 18 unique voicemail greetings for every situation. Pick your favorite, practice a few times, then record your new voicemail.
The last few years have seen a huge rise in the use of automated voicemails and auto-attendant greetings. This has been especially true for the business sector, where professionals should record friendly and polite voicemails to greet their customer callers.

According to the examples, this voicemail greeting is primarily used to interact with individuals who do not know who Mike Avery is or what he does. The second example displays a higher level of professionalism by clearly identifying who Mike Avery is, and what his relationship to the caller is.
The voicemail message can be anywhere between 10- 25 seconds. Keep it as short as you can because the prospects need to hear the vital details in it.
