I have multiple accounts from outside email providers in my Gmail inbox. Most of them have my first name somewhere in the email address, however I don't recognize the email addresses and I've never synced any inbox to my Gmail. I am out of storage now and having to buy extra. I was fine with google being a step in almost everything I do, until i started to feel like my privacy and account ownership controls were taken from me. Now I'm overwhelmed and trying to play catch-up.
