Email is good.

I’m afraid I won’t be answering Julie here.

For one, it feels a bit like spam. Like a response just marks in a database some where they’ve got a live one.

For two, that broken image feels awfully suspicious, like it’s trying to do the same.

For three, even if Julie happens to be real and it’s a genuine question, it’s just weird. What book? Why not just ask what you want to ask? Don’t ask to ask. It’s the opposite of polite.
