I don't understand this. I'm a developer, I create products. I'm not a professional writer. For me this means you value >>presentation<< more than my skills, despite I won't be a professional writer in your company...
I am not asking for paragraphs, but show me you are interested. I honestly spend hours writing and reviewing the jobs I post and it takes probably 100+ hours total from a team to hire a person. We want to hire you, but you've got to help us. :)
For me "Hey, I saw your post for [...]. I thought this looked great for me because I have worked on [...] and I am super excited to learn more about [....]" means absolutely nothing. Frankly, I do NOT know you or your company and in a job description there is nothing about the team, culture etc. But I have no other option just to make something up, because otherwise no one'll hire me.
