You must not be signed up for those emails (at least not for an environment of any real scale), because the most common reason people miss those mails is not because they ended up in the wrong folder, it's because there's too many of them to be able to read them all.
It's an incredibly common problem. Super important email, like an outage is brewing, or they are EOL'ing something which is going to blow you up (like older TLS versions), and yeah, you got it, but you probably didn't read it.
