I find it hard to believe that 90% of the resumes is that bad. To be honest, I have never been in a situation where I have to recruit people.
You are basically saying that you don't send a simple email because people don't send you a proper resume. However, by sending you a resume they have already put in a lot more effort than you do. It comes across as very arrogant when you don't even send an automated mail. I would even argue that it IS arrogant.
