I'm not sure there isn't a legal way to send a modest newsletter type emailing out without problems. But obviously you'd want to look into it. I get stuff from people I purchased stuff from all the time and I don't think I OK'd it. You'd just want to make sure you keep it really light and not set off anything with your ISP. But I'm sure there's info available on the legalities.
