There you have it, a basic introduction into how to write the best voicemail greetings. As you have seen, they’re not as easy as you’d think, but once you get comfortable with the type of information required by each, writing and recording your own should be a piece of cake. If you’ve tried to write one yourself and still don’t ‘feel you’ve captured the right essence, then please look at one of our voicemails greeting templates. When it comes to recording it, remember to rehearse your script and speak clearly. If you don’t care for your own voice, then have someone else record it, or hire a professional voice actor. Remember, there are also free audio editing software programs like Audacity, where you can manipulate your recording until you get exactly what you want.
Please leave us a message with your name, number, and any other necessary information, and we will return your call when the office reopens. Thank you for calling." As you can see, this professional voicemail greeting is similar to the absent receptionist greeting but more inclusive.
