Whether you are a solo therapist recording a voicemail greeting, or you have a whole office and need a system message, don't just wing it! Take the time to actually write out a script. Read it aloud to colleagues to make sure it says what you need it to say. Make sure to identify what your service is, to ward off any callers who aren't sure they've reached the correct person.
Hello. You have reached [Name]. I apologize for not being able to answer your call at the moment. However, if you leave your name, number, and a short message, I’ll make sure to contact you when I return.

We have collected 10 of the best voicemail greetings for business applications that we could find. Our goal is to demystify this tricky form of communication, which we detail at the end of this post. But first, it will be useful to go over some general suggestions to keep in mind if you plan to write a voicemail greeting for your business.
For example, a message like, “Hi, this is Jim. You know what to do.” Well, not everyone is going to know what to do—i.e. they won’t leave you inclusive information. Additionally, they may not leave you a message at all. Aside from this, humor can again be detrimental to your message, this time lending itself to ambiguity and costing you clarity. For example, if a message read, “Hi this is Jim, sorry I can’t answer your call right now. Please leave your name and number and I’ll call you as soon as I can, but you already knew that right? Do I need to tell you what to do?” This is worse than the previous example as this is confusing and can also come across as rude and unprofessional. Complicating a greeting with phrasing like this is sure to cause some harm. e. Ignoring Personality & Identity: Don’t use computer generated greetings. Some users leave default messages (‘you’ve reached the voicemail box of 777-777-777, please leave a message). Believe it or not, even this can cause problems. Callers may be unsure if the voicemail box belongs to you; therefore, they don’t leave a message. Also, some may even be uncomfortable leaving information through a message in a nameless voice message box. As such, impersonalization can cause ambiguity, which again can hurt the effectiveness of your voice message system. This doesn’t mean you have to make an elaborate greeting if you don’t want to, just insert your voice and name so at least callers know they’re calling the right person.
