In Gmail Compliance & Spam settings you can exclude certain addresses from the spam filter.
In my opinion, it's a good idea to do so for the official sender addresses from Google services, so they always reach their recipients. Google, of course, makes sure all such emails are properly signed and sent from the service, so they should generally be safe to recieive.
Ot course, the recipient must then abide by same safety precautions as always, as the actual content of the email, may still be dangerous or malicious in some way. That an email is properly sent only means that. It does not mean that the content is safe.
You find the Spam setting here.

I have the following options set for this NeverSpam rule.

And this is my list of known sender addresses (I added Keep today).

Here they are in a copyable list in Google Sheets.

The two at the top (cosafe & lifesify) are specific for our organisation, and not Google's.
