Small anecdote: The acceptance email to my universities study abroad program landed in my Gmail spam folder. An email that I had 5 days to react to or someone else gets the spot.

I thought it's great that I have so rarely stuff in my Gmail spam folder that I don't even have to check it regularly until I nearly missed a very important email. Apparently I was lucky that ot didn't get outright rejected.

I rather have to deal with some spam than to miss important, or even regular, emails.
