KDP Rejected Your Book Without Saying Why? The Silent-Failure Checklist

The loop: publish, “In Review,” back to Draft

You click publish. The book sits in review for a day or two. Then it silently returns to draft. The email — if you find it at all — names a category (“cover issues,” “metadata issues”) without pointing at anything specific. You check everything, it all looks right, so you resubmit the same files. Review, draft, repeat. Some authors ride this loop for months.

The trap in that loop is the resubmission itself: KDP's review is running the same checks every time, so sending unchanged files guarantees the same rejection. The way out is knowing what those checks actually compare — because the five most common failures are all mismatches between things that are each individually correct.

1. The cover text doesn't match the metadata — verbatim

This is the single most common silent rejection. The title, subtitle, and author name printed on your cover must match the Details-page fields exactly: same punctuation, same subtitle (present on both or absent from both), same middle initial, same everything. “The Complete Guide to Sourdough” on the cover with “The Complete Guide To Sourdough: Bake Better Bread at Home” in the metadata is a rejection — and it looks perfectly fine to a human, because both versions are “right.”

Check it by reading the cover out loud, character by character, against each metadata field. If you have a subtitle in metadata but not on the cover art, either add it to the cover or remove it from the field.

2. The interior title page disagrees with either of them

The same rule applies inside the book: the title page and copyright page should carry the same title and author name as the cover and the metadata. Books revised over multiple rounds often drift here — the subtitle got reworked in metadata but the interior PDF still carries the old one.

3. Spine width drift (paperbacks)

If you edited the interior after designing the wrap cover, your page count changed — and the spine width of a print-on-demand cover is computed from the page count. A cover built for 168 pages wrapped around a 174-page book fails review, even though the cover file itself is exactly what you uploaded last time it passed. Rebuild the wrap with the current page count (KDP's cover calculator gives exact dimensions).

This is also why “I only fixed a typo and now the cover is rejected” happens: the typo fix reflowed a chapter and moved the page count across a spine-width boundary.

4. The faint red outline

When review bounces a metadata item, KDP marks the offending field with a thin red border — thin enough that authors routinely stare straight past it. Before resubmitting, walk all three tabs (Details, Content, Pricing) slowly and look at every field's border. On some screens you need full brightness to see it.

5. ISBN mismatch

If an ISBN is printed inside your book, it must be the same ISBN assigned to that edition on KDP — a leftover ISBN from another edition, another format, or another publisher is a rejection. If in doubt, remove the printed ISBN entirely; KDP doesn't require it to appear in the interior.

If the email says “publicly available content”

That's a different animal — a rights question, not a formatting one. KDP is asking you to prove you hold the rights to content that appears elsewhere (including your own website or your own other editions). Reply to the email with a plain statement of authorship and, where relevant, links showing you control the other location. Don't resubmit around it; answer it.

How to escape the loop

One change per attempt. Pick the most likely item above, fix that one thing, resubmit, and note what happened. The rejection categories aren't random — the same check fails every time until the mismatch it's comparing is gone. And if you truly cannot find the rejection email: KDP support chat can read you the reviewer's notes verbatim. Ask for exactly that — “please read me the specific issue noted by the review team” — rather than asking generally why the book failed.
