Several of my coworkers still have page-long “Due to the COVID-19 Pandemic, our department will be…” auto-replies set up 24/7, even though the basic function of our office has barely changed. I’m currently working odd part time hours right now, and if there weren’t so many of these annoying emails going around, I’d have one that clarifies my email timelines, but I don’t want to be another spammer.

I might sound nitpicky but the language is important. “Might” or “may be” or “slower than usual” are vague and don’t offer the sender all that much information about when you’re really going to respond to them. Worse, they do a horrible job of protecting the time of the email receiver who, as the responder notes, is not in the office! Such a responder implies that, not only will the vacationer reply to the email, but they may not even miss a beat. They may be slow to respond, but they also might not.
