Depends if you're a world class bullshitter or not :). You've pretty much hit the nail on the head about the filters - they have some arbitrariness to them, and most people outside (and, if my experience is anything to go by, inside) HR use filters that work for them based on experience in the past. I'm not saying they are fair and unbiased (they aren't), but they work for that particular person. I for example would perfectly OK with you emailing me (if I were hiring, which I'm not) a cover email that says something like "I have the skills you're looking for, I like the area your company is in, and I'm looking for a job that allows me to bring my dog to work and have a work/life balance". That's again specific to the hiring manager tho', I'd take refreshing honesty over someone trying to visibly BS me any day. What a lot of people don't immediately see is that if a company is hiring, they're not looking to hire your resume - they're hiring a person (which a specific skill set) that they're going to spend 8-10h/day with. A cover email can convey more about you personally than a list of past accomplishments.
