Before you record your business greeting, make sure to write it down first. Finalize your script and then rehearse a few times before you record the final business voicemail.
20. Hi, you’ve reached [your name]’s phone. I’m busy making deals or rock climbing [replace with your personal hobbies], so leave your contact information and a brief message so I can call you back when I have a free moment.

This is optional, but you can also leave another form of contact on your voicemail, like an email, that the employer who is calling can utilize. This will show that you want to get back to them as quickly as possible, and you are giving them multiple ways to do so. This isn’t necessary, but can be a good step if you want to squeeze a little more into the voicemail without going overboard.
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.
