Dear Miss Snark,
Say you get a query with the first few pages as requested in the guidelines. You decide there are three or four questions on the proposal topic; the hook and so on, and you return the query in the SASE with these questions written in the margin. The writer/potential author/client then responds to these questions in an email. Is this improper? Did the agent want a hard copy response? Or is email just completely not kosher in this context? Because this is a far cry from "not right for my list." Thanks.
Respond to the questions with the same form. Paper begets paper. Electrons beget electrons. Lipsticked cocktail napkins begat ...well, never mind.
If you get something back in your SASE, and you respond in an email, there's a very very big chance the agent will not make the connection with what you've sent previously. Absent the direct instruction "email this answer to me", respond on paper. And if you're REALLY savvy, you'll include a photo copy of the page with the scrawled notes.
Not that I have trouble remembering things due to ...well, I forget what but...never mind.
