That's not just Google. My university uses Outlook and however they've set it up, I don't get spam, I get an email that I got a spam email. If I want to see the filtered email, I have to click a link in that email to a different webpage which takes a long time to load and requires multiple steps to view the message. The email also is sort of a digest so it's delayed, which is very frustrating when it decides a colleague's urgent message was spam.
