worst practice - Internet Marketing News and Blogs

At our recent Email Marketing Roundtable one of the attendees said: "I hear the phrase 'best practice' email marketing bandied about, and everyone nods sagely. I'm sure some people could give a definitive list, but where is that list? And is there a list of 'worst practice'?"

I had a little dose of worst practice this morning, something worth adding to any email marketer's Things Not To Do Under Any Circumstances Because You Will Have Angry, Disbelieving Customers list.
