I have similar, but, in my case, it's because I have an account with the delivery company, and they associate the email with my address, so I get emails, whenever a package is to be delivered at my address, regardless of its origin.

That doesn't seem relevant to the subject of whether or not delivery companies get your address from Amazon, nor to the main topic of an Amazon-only email getting leaked?

But yes, some couriers do let you tie an email address to a physical address to get notifications.

I wouldn't say it "not relevant." The symptoms are similar; but the cause may well be different.
