I don't know how practical this is, but I'd be impressed as all get-out with any company that sends marketing emails to which replies are individually read and answered knowledgeably in case I want to follow up something in them. An autogenerated reply that I should "simply" visit their web page seems to imply that they consider their time more valuable than mine. Is this another case where they've done the math and concluded that it would be too labor intensive for them to do the right thing, or are people in corporate marketing departments genuinely unaware of the impression they're making? I'd be grateful to anyone on HN in a position to satisfy my curiosity about this question.
