It’s more important that your callers feel like they can ask you for help on a subject they don’t know too well. A really easy way of simplifying your greetings is by using smaller words. Imagine yourself explaining what you want to a three-year-old. Your customers aren’t stupid, but they’re not going to always be familiar with typical business jargon. Make sure you’re adjusting your greetings to accommodate for the lack of familiarity, unnecessary details, and technical 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.
A good way to do this is to maybe add, “Have a wonderful day” at the end of the greeting. It’s short, so it won’t contradict the first point, and it makes the message more personal.
