You don’t read much advice about how to close a query letter, perhaps because there’s not much to it, right? You say thanks and sign your name. But here’s how to leave a good final impression.

• You don’t have to state that you are simultaneously querying unless the guidelines require it. Everyone assumes your query letter is being sent to multiple parties and not to a single person at a time. I do not recommend exclusive queries.
• If your manuscript is under consideration at another agency, then mention it only if/when the next agent requests to see your manuscript.
• Resist the temptation to editorialize. This is where you proclaim how much the agent will love the work, or how exciting it is, or how it’s going to be a bestseller if only someone would give it a chance, or how much your kids enjoy it, or how much the world needs this work. Basically, avoid directly commenting on the quality of your work (whether to flatter OR criticize yourself). Your query should show what a good writer you are, rather than you telling or emphasizing what a good writer you are.
• Thank the agent, but don’t carry on unnecessarily, or be incredibly subservient—or beg. (“I know you’re very busy and I would be forever indebted and grateful if you would just look at a few pages.”)
• There’s no need to go into great detail about when and how you’re available. At the bottom of your letter, include your email address and phone number. About 98 times out of 100, the agent will email you if they’re interested and set up a call via email if they want to talk.
• Do not introduce the idea of an in-person meeting. Do not say you’ll be visiting their city soon, and ask if they’d like to meet for coffee. The only possible exception to this is if you know you’ll hear them speak at an upcoming conference—but don’t ask for a meeting. Just say you look forward to hearing them speak. Use the conference’s official channels to set up an appointment if available.
