250? That could easily be only 2-3 days of emails. You can’t declare “email bankruptcy” for only a few days worth of emails. I average about 200 a day, so if I was on vaca and came back to only 250 mails, I would be putting in a ticket with IT, thinking something was broken.
Yep. When I was at an on-call job and sometimes had to check email while I was off it was a little more tailored; I would specify whether I had access to email or not, and give more detailed info on who to contact for what if I didn’t. Nowadays this is fine. And fine for me on the other end as well. I just need the relevant info, it’s not remotely a big deal if someone’s out.

Thanks for explaining, that makes sense. To me, it seemed like a well-communicated coverage plan and I would have especially appreciated the setting of expectations on how soon I could expect a response so never would have even considered that to be condescending.
No one thinks much about cybersecurity while traveling. However, email security company Tessian warns the out of office message actually plays right into the hands of threat actors and cybercriminals. It’s a social engineering attack vector that no one thinks about. The out of office message is ubiquitous and handy. But if it includes any personal information at all — such as attending a funeral or going out of the country — attackers have all the information they need to impersonate the person who is out of the office, without the attacker having to do any real work.
