Whether you’re out for the day or are off for the week, the first rule of an out of office voicemail greeting is: let callers know when you’ll be back! You’ll save them the frustration of continuing to call and yourself the hassle of listening to redundant voicemails. It’s also a good idea to set the expectation of whether you are answering messages while you’re away, and who they can reach for assistance in your absence.
Expand your opening to with 'Thank you for calling [insert company/individual name]' or 'You've reached the voicemail of [insert company/individual name]'. This personal touch goes a long way towards building a rapport even when you're not available to answer the call directly.
