Do Crappy Sales Email Templates Lead To More Revenue? [SlideShare]

I've been mulling over this concept for a while - do the crappy emails I send on a lazy day actually close more customers than my most personalized ones? 

To be clear, here's what I define as a "crappy email" -

This prospecting email says nothing about the prospect or about my business - in fact it sounds like it could be from anyone in the world. It presents no unique value. 

But if someone does respond to this, they must be truly interested in generating inbound leads, and don't care about anything else I said. 

To dissect this concept further, I put together the SlideShare below. I'd love to hear other stances on this in the comments.
