If you queried me by email I have responded.
I either sent you an email
1. passing on further consideration (stupid me, I know);
2. telling you I had your query and needed more time;
3. asking for the manuscript.
If you queried me and have not gotten one or more of those emails, query again. DO NOT email asking if I got it. I didn't-- (or you failed to say Hola Snookums in the email or sent it to every agent in the TO: line--those are emails I discard without response.)
