Steve writes, "My email list has grown very large over time (it's about 80,000 now). I'm sending out a non commercial email article of a religious nature. It covers a controversial issue which I believe may lead to some recipients flagging it as SPAM, (even though I have an unsubscribe button with my dedicated hoster). I want to be able to link to articles at various websites but I don't want those websites to be in danger of getting blacklisted. How do I avoid this?"
