A good voicemail greeting is short and professional, lets people know that you’ll get back to them, and invites callers to continue engaging with a call-to-action. You should also show your personality if you’re in an industry or role that allows that. If your industry is more conservative, however, you’ll want to keep humor and personal touches to a minimum. A greeting Your name Your company A simple explanation for missing the call (e.g. you’re away from the phone or are on holiday) A rough estimate of when you’ll get back to the person An alternative person to reach out to (if you’re out of office) An alternative mode of communication (if you prefer email or text) A call-to-action such as “Leave a message” or “Send me an email at [email protected]”

Is your refrigerator running? You better go catch it! Corny jokes like this don't work anymore...and won't work in your voicemail greeting. Saying things like, "Hello, you've reach the machine that lives inside Mark's cell phone. Leave a message and I'll tell him!" are really unappealing and aren't even funny.
Your voicemail doesn’t have to be monotonous or impersonal. What you need is something that is unique to you but works in a professional manner.
