"When closing your voicemail, say that if you do not hear from them in three days, you promise to call back. Three days later, start your voicemail (or live call if you reach the person) with, 'As promised, I am calling again to share...' Close with, 'If you haven't had a chance to return my call, I promise to call back in two days.' Two days later, call back and open with, 'As promised, I am calling back...' The message you are sending is that you keep your promises!"
That’s why it’s never been more important for salespeople to be good at leaving messages. Not only that, but voicemail can—and should—be measured, coached, and improved.

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.
Once done recording, go to the Voicemail greeting to find all the recorded voicemails. Click on the "Play" button beside the name of the voicemail to play it. To change the name of the recording, tap on it, and enter the name of someone who called you and set it as active. The caller will hear the voicemail greetings once they called you.
