Question: Yesterday I got a rejection email from an agent, no biggie. However, despite being addressed to me, it appears to have been written in response to someone else's query. (This query was still in the email)
And this is where the etiquette pickle comes in. I'm assuming that I'm rejected, because despite the agent's public statements the email clearly states that he's not interesting in any new clients. That's not my problem.
My concern is about the other guy. Did he get my rejection? Did he get anything at all? (no knowing is just awful, trust me, I know) However, I don't want to get some poor overworked assistant into trouble for the mix up, or leave someone hanging because they didn't get the message.
What should I do?
Answer: Nothing. The other guy got the same rejection you did.
If you can't live with doing nothing, it's ok to email the agent back and say "this one was intended for someone else by the looks of the query." You won't get some poor overworked assistant in trouble; this kind of thing happens every once in a while. I've done it myself.
