Apple email

I would like to add snaps but can not Can someone explain how these iCloud emails are from iCloud? Apple? I noticed that the Find Me app had send me email only to find it appeared wrong and fake . When I blocked it I noticed some of my emails from Apple were then blocked and not others from “Apple”.

I have had cyber data breaches for over three years when my first MacBook was completely hacked and wiped. I have had multiple and I mean multiple- Apple devices. Ten iPhones at least, five watches, an ulte watch, and two MacBooks all breached. Over and over. My Apple ids and phone numbers all have been changed so many times I can’t count. It never ends. Now on a completely new iPhone 15 somehow my new email is linked to receive mail only after I log into an old yahoo or outlook email I do not even have or use? Any suggestions? My backup always ask if I want to backup my Chinese/Japanese keyboards. I don’t use either Chinese or Japanese keyboards so where is this coming from? My cars which were never connected are also affected and synced. Two BMWs and a Bronco. Every rental car I have rented in past year also affected via radio n yet I don’t connect phone and car?

thank you
