2. Quickly Provide the Relevant Information. When someone reaches your voicemail, it’s important that you help them confirm that they have reached the right person by providing all of the relevant information that they will need.

Departments and teams are typically organized by function – customer service, tech support, sales, billing questions, etc. When a team is busy handling other calls, encourage your callers to leave a message and reassure them that you will get back to them within a reasonable time frame. It’s important that you actually follow through to avoid upsetting your callers.
I have a confession to make: I haven’t recorded a new voicemail greeting since 2014. In the past four years, I (hopefully) have become more articulate, poised, and self-assured. But hear my voicemail recording, and you’d think I was still new to the work world, a little unsure of myself — and probably not an authority. Obviously I need toupdate it. And if you haven’t changed your voicemail greeting in over a year, you’re likely in the same boat. After all, a professional voicemail recording boosts your credibility, makes you seem more competent, and encourages whoever’s listening to it to continue the relationship. A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction. With that in mind, I’ve written 18 unique voicemail greetings for every situation. Pick your favorite, practice a few times, then record your new voicemail.
