In a University it is completely out of control. Every individual you ever meet or encounter electronically seems to generate an email or meeting invite from them, their university, their department, their school/faculty and from associated departments with a shared resource that you are required to understand. Sometimes it's multiple messages per day, and I haven't worked there in 3 years. Anacedata as I have only worked at one university.

It's out of control in general. Email itself is a little bit like phone calls these days - almost entirely useless to me as a medium due to the amount of spam generated.

Email is, of course, worse. For every 15-20 emails I get maybe one of them I was expecting or is personal. It's just a glorified spam box.
