Personally, I’d think it’s funny to receive an OOO like was in the video, at least the first time. It wouldn’t fly AT ALL at my company, but it’s at least interesting. All I really want to see is how long you’re out, and who I need to contact instead.
Don’t beat around the bush! This is an expression that means you should get to the point. That is, you should make your message direct and brief. This will let the recipient quickly know that you’re not available and who they can contact instead. You can start with a simple greeting and then proceed to the message like in the following examples:

Dear Customer, Our office will be closed from [date] until [date] and close again for December and January to welcome the New Year. We wish you the warmest holiday. Regards, [Company name]
But I also believe there’s meaningful power in the mundane cultural norms we set and practice. Email, for better or worse, makes up a large chunk of how knowledge workers communicate. So much of this communication is muddled by broken email habits and larger anxieties around performing productivity. We’re constantly nervous about asking too much of others or doing too little on behalf of our coworkers. But we’re also stuck in work patterns that force us to communicate constantly and normalize working and demanding things from colleagues at all hours.
