One way to avoid this is by writing a script. When you’re writing a script for your business voicemail greeting, make sure to look over it to see if there’s any slang or business jargon that could mean two different things depending on your point of view. If there’s any potential for confusion, revise the script and simplify the language. You can always ask a friend you don’t work with to see if your message is clear as well.

Put yourself in your listener’s shoes. Have you ever tried listening to someone on the phone who’s just talking so fast?
