Rehearse or write down your message before recording it. Remember that old saying “practice makes perfect?” It’s certainly true when it comes to creating an electronic greeting. The more you’ve rehearsed, the easier the message will be to restate. If you don’t have time to practice, writing down the greeting before recording it – and then reading it aloud from the paper – may help you stay focused on the correct wording.

I have a confession to make: I haven't recorded a new voicemail greeting in nearly a decade. Since then, I've (hopefully) 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.
It's never been more important for salespeople to be good at leaving voicemails. Not only that, but voicemail can — and should — be measured, coached, and improved. First, let's review general voicemail etiquette. Keep your greeting up-to-date. Let callers know when they can anticipate a response. Share your name and company affiliation. State the intention of your message. Include your contact information at the beginning and end of the message. Be concise. Share your availability.
