I don't send bulk email, and I don't send marketing email. If you send me mail, I will not share your email address with any third party. If you're a teacher informing me that you've adopted my books, then by default I will list your name, with a link to your school's web site, on my site, but I will not give out your email address. If you don't want your name listed, let me know. If you adopt my books, then I may send you email from time to time, e.g., to let you know when a substantially different edition is coming out. If you don't want to get that type of email, let me know.
