My first query letter was eight paragraphs long. The last one I wrote contained three sentences. It was none the less polite, contained my pitch and my achievements. Every word counted; played a very deliberate and strategic role.
The people you’re querying hear from thirty of you a day. A day. While they’re doing other, far more important things. They read your pitch on tiny little screens they keep in their pockets. They decide in 5 seconds whether or not your 90 pages is worth their very elusive time. If you finesse the hell out of those three lines and a thousand stars all line up at that very moment then maybe they’ll reply in kind. “Send it” is usually the most they’ll say.
