Just imagine the ease your customers feel when they receive a warm and friendly automated message that sounds human. Hence when you craft autoresponders, keeping your brand’s voice and style is very important to give a human touch.
Here are four tips to help you create an effective after-hours voicemail greeting: 1. State your business name and hours of operation upfront. The first thing your callers should hear is the name of your business or organization. If they are calling when you are closed you should also be sure to let them know your standard business hours.

Meanwhile, I do sometimes put up long ones when I will be away for some days during a season in which there are a confluence of three or four very likely reasons someone would contact me, and who else they need to contact isn’t the same. Like, it’s high llama grooming season, and generally during this month I get two or three requests per week for each of llama bleaching (for which my backup is Stella), llama shaving (for which it’s Arturo), and llama perming (for which it’s Carter). My message says I’ll be out until blah blah, and if it’s not an urgent llama grooming issue, I’ll get back to you after that, but meanwhile, for urgent llama grooming here’s who to call.
That said, be careful with messages that are this curt. Make sure you're familiar enough with your audience — and your boss, for that matter — to know that this sort of out-of-office message will be met with a snicker, and not with annoyance.
