Verbal Content – generally, you should use 100 words to make up 1 minute of content produced with background music. In other words, one to two paragraphs per minute. The topic can range from product promotions to general company information.
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.

Consider adding 'You can also email your query to us at [insert email address here]. These queries will be answered within [insert time frame].' Again, if you intend to make a promise to your customer in a voicemail, ensure you keep it.
Sound upbeat in your message. When recording, be sure to say your message with a smile on your face. It’s obvious when people aren’t happy in their message. Since your work revolves around keeping happy customers, do your part by keeping a happy-sounding voicemail message.
