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.
