A secretary in a doctor’s office creates a voicemail greeting that says, “If you have a scheduled meeting with us, we could use copies of all your medical documents from last year, so come prepared.” Using the word “could” gives patients the impression that they don’t necessarily “need” last year’s documents. See the difference between “could” and “need”? Your word choice can impact a future meeting significantly. If you want a customer to perform a specific action, you need to pay close attention to how you express your calls-to-action.

The right way to leave your phone number is to start saying your phone number with your area code and then take a 2-3 second pause while the person listening to your voicemail message gets a pen and paper. Then, continue with the next 3 digits, make another 2 second pause, and then say the last 4 digits. Then, slowly repeat your phone number again.
