Our subscription includes unlimited talk, text, picture messaging, ability to share responsibility for the phone number with a partner or team, dedicated business voicemail, set business hours to direct callers to voicemail when you’re off, and much more.
Business owners and everyday customers know that there will be times — like the holidays — when things get busy. When you’re transparent about why you weren’t able to come to the phone, people typically understand and are much more willing to be patient with your business. If the goal is to encourage more people to leave a voicemail, your greetings have to be actionable and clearly dictate what you want the caller to do. Having a caller go to voicemail is not the end of the world; it’s going to happen, so you have to make the most of it.

You can fine-tune this similarly to how companies A/B test their websites, ads, call scripts, and anything else that requires a change. The more elements of a call you look at, the more likely you’ll be able to optimize your voicemail greetings. If you jump right into the greeting without saying “Hello,” go back and make your greeting more personal on the second attempt.
