The only thing that isn’t boilerplate in mine is the inclusion of “But what if I have a word emergency?” before the who to contact stuff. I removed it at one point and people asked me to put it back in because it made them smile. And yep, we’re writers so the only emergencies we deal with are ones related to words.
Oh, it’s part of a much larger set of problems. He will put in the subject line “don’t read until Monday,” also not understanding that when I say I do not look at my email on my off days, I really do not see them, because I don’t open my work email out of work. And that I have a personal email account, that is not my work account?

By providing this information for anyone who tries to contact you, it ensures important emails don’t go unnoticed or ignored.
I hate when senders ignore the instructions in my OOO message. Usually, my message is something simple like: “I am out [Dates], returning to the office [Date]. Please contact Jane (jane’s email address) in my absence. General [department] questions may be sent to [general dept email address].” To me that says if you are sending me anything then I won’t see it until I return. If you have something you need to be resolved right away, you can contact Jane or send it to our department inbox (where it should be going anyway).
