Creating a voicemail greeting might not be fun, but with the scripts I’ve shared, you should have an easier time. No need to practice time and time again — simply plug in your name, company title, and other details, then read it out loud to your phone’s voicemail greeting recorder. With a professional greeting, you’ll continue nurturing prospects even if you don’t pick up the phone.
You’ll want to have your office hours in the voicemail so that cleaning customers know when they can connect with you. You don’t have to always be available during all of those times, it’s just the possibility you’ll actually pick up your phone or will be able to give them a call back during those hours. Adding in office hours makes your business sound much more professional. It’s the sign of a more established, well-run company to have business or office hours.
