The bad news is that, if you are a millennial, you cannot afford to regard leaving voicemail messages as obsolete. There are four generations actively participating in the workplace. This is unprecedented. It means that, while Baby Boomers are learning to text, millennials also must become adept at using voicemail.
Repeat your phone number twice. People seem to forget that the receiver of their message has to write the number as you say it. Don’t rush through it. Even when you say it slowly, it’s hard to get down the first time. So repeat it again, so they can check to be sure they got it down right.

Apple makes it easy to save and share voicemails. This is excellent for business or scholastic use. Share important messages with coworkers or classmates, or upload them to a computer anyone can access. Just be careful you’re sharing only what you want to.
