Try to avoid unnecessary phrases that only make your greeting longer, like “leave your name and number and what you’re calling about.” Most people know what “leave a message” means.
Now that you are aware of the tips to create an efficient voicemail message, the next steps would be to understand from the examples below how you can get started.

Humor also leaves a lot of room for misinterpretation—which subsequently weakens sincerity and authority. A caller can be very turned off by merely misinterpreting your joke. Why take this risk? Additionally, this could even cause callers to question your character. Say, for example, the president of a company’s mobile phone voicemail greeting was funny. What’s to happen if the caller didn’t like or get the joke? What if they found it offensive? Another scenario is that a caller is reaching out to you for the first time—i.e. they have no idea regarding your personality. What next? The point is, with this type of greeting, humor is bound to be more divisive so just avoid it altogether. c. Poorly Pacing Your Message and Bad Time Management: Don’t speed through your message. Speak clearly so callers know what to include in their message and when to leave the message. At the same time, don’t drag your message out. No one wants to sit through a diatribe. Just get to the point clearly.
After you recognize yours and your customer’s pain points, it will be much easier for you to classify what instructions that you need to mention in your business voicemail greetings. Modifying your calls to action will help to make a big difference in eliminating pain points and enhancing the customer experience.
