Your voicemail doesn’t have to be monotonous or impersonal. What you need is something that is unique to you but works in a professional manner.
If you want them to leave a voicemail, tell them right from the beginning, “Please leave your name, reason your calling, and the best way to contact you.” If you want them to call you back during normal business hours, tell them, “Please call back during normal business hours.” If you want them to call back prepared for a lengthy conversation, you can say something like, “Please refer to our website’s FAQ page,” and then provide the URL. Self-service should never be underestimated.

Ensuring that your tone and message is nothing less than perfect, you’ve to rehearse it over and over again. Script it down, and let your crew sift through it. Perform several trials runs on your business voicemail greeting until you come up with an absolutely apt script. Remember to update it often so that you can include/remove some lines based on seasonal business changes.
In previous blogs, I’ve mentioned the importance of making a good first impression on a potential client. Most of the time, the first contact will be over the telephone. Since we are often in session, it is very likely that the first time a client hears our voice is on our voicemail greeting. This is why a professional greeting is so important. Identify yourself because you need to reassure the client that they have called the correct number. Clients will be a lot less likely to leave a message if they wonder who will get it. Use a warm friendly voice to say something like, “You have reached xxxx, licensed mental health counselor.” Tell clients what to do if they are in crisis. Although it seems obvious to us, clients may not realize that it could be several hours until we can return their call. I suggest something like, “If you require immediate assistance, please dial 911 or go to your nearest emergency room.” Ask for what information you need. Yes, the obvious name and number, but if it would be helpful to get their insurance information, ask for that, too. Give clients an idea about when you’ll return their call. Common business practice is within 24 business hours. Any extra messages or information you’d like clients to know. For example, if you are no longer accepting a particular insurance plan, the end of your voicemail greeting is a great place to convey that information.
