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.
Expand your opening to with 'Thank you for calling [insert company/individual name]' or 'You've reached the voicemail of [insert company/individual name]'. This personal touch goes a long way towards building a rapport even when you're not available to answer the call directly.

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.
“Hey there! This is [name] at [XYZ company]. Thank you for calling. I can’t take your call right now but if you leave your name, contact info and reason for calling, I’ll call you back right away. Take care and speak with you soon!”
