The VMO service worked well as a contact service for our class reunion. It worked as described and was a great resource for our classmates.

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.
You can trick the caller with funny jokes before the actual greeting message beeps. Keep such kind of voicemails for close friends and family members. They will find it amusing soon after making the call. The machine says Hello, not Me. So respond to what the mechanical device orders you. Play the game of in and out to find me out! Listen to the voice after the beep. Yes yes yes, we are not yet in and we do not want to bore you with a long voicemail text. Leave your message after the beep. I cannot lend my ear so I have kept the machine as my assistant. Record. I love your voice! I want to hear you. Speak up to record.
