Do they want to sit through an IVR menu that may or may not direct them to the right person? Do they know you’re a one-man/woman team and there’s no reason to sit through a menu? Skip the menu entirely and let them leave a message as quickly as possible. There’s no reason to add any additional steps or make your customers go through leaps and hurdles to leave a simple voicemail. When you identify what your customers’ pain points are, you make it much easier to determine what you want them to do to save everyone from the unnecessary stress.
7. Explain when you expect to return calls. This is crucial. Instead of telling clients that you'll return their call when you have time, tell them when you return calls.

Once you identify your pain points, you’ll find it much easier to identify what instructions need to be present in your voicemail greetings. We hinted towards these before, so let’s just break down another example. If you want your customers to leave a voicemail, but you also want them to visit your website for additional help regarding their issue, give them a clear call to action, like a website address they can easily write down while they listen to your message.
