I also believe that equeries are probably easier to reject. Some I never have got an answer of rejection from the agent, but they usually state that, if they are not interestest they will not respond. With that being said, of all the snail mail queries sent as well as e-queries, I've received a request for a full and a partial from an e-querie. One querie I sent my first 50 pages and the other was based on the query alone. Go figure, it's a funny business that I've yet to figure out. I just keep writing and sending out queries, entering query hell in SYW, and keep my fingers, toes, all the hairs on my body crossed in hope someone will like my work. Good luck!
