Once you’ve found your dream editor, my hope is that you asked them a few out-of-the-box questions before signing the contract. And my other hope is that your editor had a resounding “yes” to said questions.

Because it’s not just about attaching the manuscript, typing something like Here it is! Can’t wait to hear your thoughts, and hitting send. Unfortunately, that’s where a lot of writers stop. The file goes out with almost nothing around it—no context, no map, no sense of what you were trying to build. But think about this: your editor is about to spend weeks living inside your book, and you’ve told her almost nothing about it.

She’ll do the work anyway. A good editor always does. But with no context, she has to guess—at your intentions, your influences, which choices were deliberate and which were accidents. Good editors guess well. But a guess is still a guess, and every guess that misses becomes a note you’ll spend a whole revision undoing.

The handoff—what you send before the editing starts—is the easiest way to make your edit sharper. Here’s what that looks like.

Context isn’t extra credit—it’s part of what you paid for

Imagine walking into a new doctor’s office, sitting down, and saying Something’s wrong, fix it—then refusing to fill out the intake form. No history, no symptoms, no “here’s what I’ve already tried.” The doctor could still examine you, but she’d burn the first half of the appointment rediscovering things you already knew.

Sending a manuscript with no context is the same move. The intake isn’t busywork that delays the real thing. It’s how the edit gets aimed at your book instead of a generic version of it.

(A note on how this works in practice: some editors send you an intake questionnaire before they start—if yours does, fill it out completely, even the questions that feel obvious. If yours doesn’t, everything below is your version of that form. Either way, you’re the one who benefits.)

Start with what every editor needs

Before we get into the differences between edit types, there’s a core set of things any editor—developmental, line, or copy—will work better with. Send these no matter what you hired for, and think of each one as answering a question your editor would otherwise have to guess at.

• Where the manuscript actually is. Be honest—rough first draft, or tenth polish? This answers how hard can I push? An editor handles a raw draft differently than a nearly final one, and pretending you’re further along than you are just gets you notes pitched at the wrong altitude.

• Your comps, or where you think it sits. Two or three books yours is in conversation with. This answers “What shelf does she think this belongs on?” so your editor stops editing toward the wrong book. A cozy mystery and a literary thriller can share a plot yet need opposite edits.

• Your real deadline, and what “done” means to you. Not just the date—the destination. Are you editing toward querying agents, or straight to self-publishing? This answers what am I actually preparing this for?

• The two or three things you’re secretly worried about. The slow middle. The ending you’re not sure meets the reader promise. The character who feels flat to you. This answers where does she need to look hardest? Naming your fears doesn’t invite attack—it points the flashlight.

• Your non-negotiables. The choices you will not move on: a present-tense voice, a nonlinear structure, the sentence fragments you deploy on purpose. This answers what’s off the table? A good editor would rather know your lines up front than spend a margin comment discovering them.

Then send what your specific edit needs

Here’s the biggie: the three main edits do very different jobs, so they need very different things from you.

If it’s a developmental edit, send your intentions.

A developmental editor works on the big architecture: structure, pacing, character, whether the book delivers what it quietly promises the reader. She’s editing toward your vision, which means she needs to actually know what that vision is. So send the themes you’re chasing, and the emotional arc you meant to build. Send the backstory that never made it onto the page but shaped every decision a character makes. Tell her what you want readers to feel when they close the book. And tell her how much surgery you’re open to—an editor who knows you’ll consider cutting a whole subplot works very differently from one tiptoeing around a writer who won’t move a comma. The more of your intention she can see, the less she has to reverse-engineer it from the pages alone.

If it’s a line edit, send your voice.

Line editing lives at the sentence level—rhythm, tone, word choice, the texture of how you say things. It’s the edit that touches your voice most directly, which is exactly why she needs to know which parts of that voice are deliberate. Think of it this way: The fragment you love, the run-on that’s meant to feel breathless, the regional cadence that isn’t a grammar slip. Point her toward a few writers whose sentences you admire, so she can hear what you’re reaching for instead of guessing. And flag your intentional rule-breaking up front—otherwise it comes back “corrected,” and you spend your review restoring the very choices that make the book sound like you.

If it’s a copyedit, send your canon.

A copyedit is about consistency and correctness—and consistency needs a source of truth. If you already have a style sheet, send it. If you don’t, ask whether she’ll build one as she goes (most copyeditors will, and it’s worth its weight later). Hand over the spellings of invented names and places, the terms you want capitalized, the grammar you’re breaking on purpose in dialogue, and which style guide you’re following (or just a note that you’d like her to choose). Every rule from your book’s private rulebook that you supply up front is a rule your editor doesn’t have to reconstruct one query at a time. It’s the difference between an editor who knows your character’s name is spelled “Mikael” and one who has to flag it forty times to be sure.

The paradox of the handoff

Now, here’s the part that surprises writers: the things you’re most tempted to hide are usually the things most worth sending.

The areas you’re most scared of? Don’t keep quiet. Flag them, because a good editor, told this is the chapter I’m most nervous about, gives it her most careful attention, not her harshest. Your fears, handed over, get closely looked over and handled.

So the handoff isn’t paperwork you complete before the collaboration begins. It’s the first move of the collaboration itself. Your editor’s whole job is to help you make the book you meant to write—but she can only aim at a target she can see.
