As probably know, a professional voicemail greeting can make or break leaving a great impression. However, it all starts with your voicemail script.
A virtual business phone system like Grasshopper can help you create a professional, reliable voicemail greeting. It includes instant response and custom greetings, as well as access to the Grasshopper Voice Studio and professional voice talent for a one-time fee of $75.

When your small business is closed, ensure that your callers know that! If appropriate, you might want to reiterate your business hours to manage callback expectations.
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.
