Tell People What You Want Them To Do—Here’s my voicemail greeting: “Hi, you have reached the voicemail for Todd Smith. At the tone please leave your name, phone number, the purpose of your call and the best time to reach you and I will return your call as soon as possible. Thank you”

While missed calls aren’t ideal, you can let your caller know you’re still there for them by having a great voicemail greeting. The best business voicemail greetings let your customers (and potential customers) know why you’re not available and how they can best get in contact with your business. They are also short and to the point. You usually want to keep your greeting between 6 and 24 seconds long so callers don’t hang up halfway through.
On hold messages can be recorded for many purposes, such as promoting your business, answering FAQs or announcing important customer service information. It's important to be clear in the message you are trying to get across. Confusion leads to disengagement and reflects badly on the brand. Determining your callers' wait times is necessary to determine the required length of the on-hold message. Making the recording too short can lead to the message being played too many times. This can be repetitive and lose the caller's attention while they hold.
