And I never liked Gmail the client. It's not as godawful as Outlook, nothing even comes close, but it always gets in my way and does things in weird Googly ways. I'll stick with Kmail, thanks.
Incidentally, those emails are definitely from less-than-reputable (and in some proven cases North Korean) actors trying to get footholds into Western Companies! Crazy!
I set up specific folders based on aliases. Thanks to GDPR I have found a few companies that have shared / sold my data illegally (the company-assigned address popped up somewhere else) and managed to have them delete my data right away.
I fret losing my domain, and that my recovery addresses are Gmail and Outlook - which could be lost at any time.
I would like to see government issue a lifetime inbox in the same way they issue you a SSN, a passport or driver license so I can have that as last line recovery.
But on the other hand, if we had that politicians would likely enforce mandatory identification across all web services…
