OK, what do I do now?

Personally, I would probably wait another week or two and then politely email the agent you queried (not the original agent) simply inquiring whether he received the query since things DO get lost in the cyber world. I've read that many agents don't mind simply responding about whether they received the email or not. (And of course I'm operating under the assumption email queries are kosher with this agency, which would seem to be the case if the original agent didn't tell you otherwise!)

You might try sending a copy of the query by snail mail with a SASE. If he doesn't respond to that either - well, I don't think you'd want an agent who doesn't respond to e-mail or snail mail.

Welcome to agent hell. First, understand that agents get dozens of queries a day, often more & they want to respond to all but can't. A two week wait is, alas, not that long. The problem is that if you e-mail agent #2 again, there's no guarantee he or she will remember your first e-mail...in fact, it's more likely not.

I'm unpublished, but I finally got an agent & I've done a lot of research, so take this advice for what it's worth. I'd wait a week & resubmit the query, apologizing for submitting it a second time. (Of course your query was in the body of the e-mail, right. Agents won't open attachments for fear of viruses.)

More important, I got enamored of e-queries because they're so easy, but e-mails are just as easy to erase. So I went back to snail mail queries, and I've had better luck getting responses. If you get organized, you can do quite a few a day. It's just a pain.

If you go the snail mail route, invest in good-quality paper, make sure you know the "rules." (Either check out agent web sites or Larsen's "How to Write a Book proposal" although that's most useful for non-fiction. And proof, proof, proof. One typo & you're toast. And, remember the SASE--otherwise you'll never hear from them.

Finally, be prepared to send out 20, 30, 40+ queries and send them out as fast as you can, making sure you note in your query you're sending out multiple submissions. Don't get discouraged. You'll get lots of rejections and lots will never respond. Just shrug & keep going.

I vote for giving it a little more time. It's the end of summer and for all you know the agent could be on vacation right now or recently returned from one with a backlog of email to sort through. If you don't hear anything within the next few weeks, you might politely ask if the agent received the email or not. I know it must be hard to wait, but patience has its rewards.
