While email and text support saw an increase in recent years, many customers, partners, and potential hires still prefer to call your company directly. When writing your voicemail script, include basic information such as a short greeting, your company name, an invitation to leave a short message, and the time frame in which the caller can expect a return call. If relevant, you may want to include your office hours, extensions for company departments, and the contact information for your office manager or HR department.
It also ensures that, in the age of voicemail transcripts, your number stands out at the end of your message. And because most phones link to numbers automatically, all your prospect has to do is press the number provided at the end of the transcript to easily call you back.

A compelling sales voicemail won't be particularly effective if your prospect has no idea how they should respond. You can't just rattle off what they stand to gain from leveraging your product or service and then hang up. Always offer some next steps or insight on what they should expect next — like another phone call or a follow-up email.
