> you don't think engineers who build web crawlers cannot build email classifiers?

Nope, I don't. So many things get constantly marked as spam in my inbox, even server notifications, from the same domain, same daily emails, marked repeatedly as "not spam", and added to address book.

Then there's the second problem of google support... your 2fa passwords, email-authentications, password reset links, etc. will be sent out, gmail will send them to spam, your users won't see/find the email, and there's nothing you can do... noone to call at google that would actually listen and try to do anything, no penalties if they don't do anything, only hope that your service is large enough that it gets some traction on twitter or here and some random googler sees it.
