Hello -- I'm a newbie: new MG novel, new at querying, new to forum...

Anyhoo, sent out 10 queries (5 last week, 5 this week) -- and I got a rejection in 4 minutes flat. I'm pretty sure it was a form, even though it was addressed to me (and spelled my name correctly). I didn't think my email server even worked that fast.

I got another email rejection (explaining it was a form, in case I didn't recognize it from the "Dear Author" intro) and a request for a full (yay!).

So what's your fastest query rejection time? Or longest (with a reply, not those lost in space). I did send out 2 via snail mail, but I expect those will be returned with warm holiday wishes...

Also -- do you send queries in batches or all at once? Is there an advantage either way?

Thank you!
