Whatever you decide before heading out for that much-needed time off, it’s imperative that you set up an out of office reply. Your customers and co-workers don’t get that same pause button as you do. That’s why you should inform everyone that needs to know about your time off.
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).

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?
That’s just sloppy. We always check who will be available, because usually someone is. We also have a service address, and usually use that for OOO–messages. Then the ones working are responsible for those messages. That said, in my branch nobody seriously awaits an answer in July, but I’m in academica.
