Written below are some of the examples in which different types of templates are used to set up a reply in English.
I start work at 9.30am but always leave the OOO on until at least then and schedule it until 10am – that way if the backlog is terrifying, people who email me that morning will know why I’m not replying straightaway. Similar to how some people mark their first day back from a few weeks off as out of office so they don’t have meetings (which is a great idea although I rarely do it).

An out of office message is a compact text that conveys the most important facts: How long you’ll be unreachable, when your contacts can expect an answer, (optionally) the reason for the absence, and, if necessary, a personal note. A referral to another email address, e.g. to one of your colleagues, is often helpful or even necessary.
After I tweeted this example, dozens of people sent me examples of OOO messages they’d set or particularly good examples they’d seen in the wild. One example from a boss (via a TikTok) who offers emailers a decision tree of sorts. “Option 1.) Wait it out. Ask yourself, ‘is this urgent and important?’ If not, take a beat…you and I will be better off with this expectation set now,” the email begins. This one stands out because it’s extremely detailed, manages expectations and also offers who to contact in different situations. It models good behavior of taking time off, but also gives the original sender a variety of option. Most importantly, the responder forces the original sender to assess whether this is actually an urgent request.
