All of these example are an easy insta-kill for me, especially if the placeholders like "problem" are filled generically. What bothers me more are personalized mails like this one: Hi <my first name>, Just curious what your impression of <product> is so far. Are there any technical issues you've come across which could be blocking you? Do you/your team have a particular project in mind, or are you just trying to keep up with the latest in <our technology>? -<sender first name> I have to think twice, if this is really auto/mass mail. This probably converts much better than the article's lines, but is also a different case.
