This. I’m surprised more people dont havent mentioned this, but this has always been my back to work routine – and sometimes if vacations overlapped, I’d find a summary email of “While you were away, X,Y,Z happened, I covered A, but you might want to check on B and C” which was always very helpful.
She continues: “However, there should be a way for whoever is emailing you to have an urgent request handled, and that should be included as part of your OOO as well as being known to your work team (supervisor and colleagues). That might look like including a coworker's email on your OOO or it might simply involve setting a forwarding rule for while you're away, so that your email goes to the colleague who's covering.”

Please accept our apology for the inconvenience this may cause. We are thankful for your understanding.
There are a million reasons why people feel the need to sheepishly telegraph that they’ll be checking email while OOO: a toxic workplace culture; a set of bad managers who don’t model work/life balance or use manipulative tactics like saying, ‘feel free to take some time if you need it’; companies that are so focused on lean growth they don’t have anyone to pick up the slack when an employee opts to take time off. These days, merely having the confidence to step away from your job by taking the vacation time granted to you in the terms of your employment agreement is still a privilege in the American workforce.
