Agreed. Many years ago I set up a personal email address for that very reason, i.e. one through which I only expect personal 1-to-1 correspondence, and which I only hand out to family & friends, never to companies (which easily get hacked and/or one day decide to reuse your email address for their newsletter).

I have one of those personal correspondence email addresses, but someone got "hacked" and their address list was scraped, and now I get spam to that address.
