Why is Send to Kindle not working?

Answer five quick questions to separate an EPUB problem from an Amazon service, email, account, library or device problem. Your answers stay in this browser.

Illustration of a failed file on the Send to Kindle website.
Start with the visible result. A failed upload needs a different fix from a delivered book that is hidden by a library filter.

Five-question check

Find the most likely cause

No Amazon login is required. This tool does not contact your account or upload your book.

1. What do you see?

What this tool separates

File problem or delivery problem?

01

EPUB file

One EPUB fails while a known-good file works. Inspect its package, manifest, spine, XML and cover metadata.

02

Amazon delivery

Several files fail, stay queued or the service reports an outage. Changing a healthy EPUB will not fix that path.

03

Library and device

The item reached the account but is hidden by the account, All/Downloaded view, filters, title metadata or sync state.

Already know the EPUB is the problem?

Run the private browser check to inspect cover metadata and the package errors most likely to block delivery.

Quick answers

Before you retry

Does this connect to my Amazon account?+

No. It is a browser-only decision tool. It cannot see your library, orders or device.

Can it tell whether Amazon is currently down?+

It can identify symptoms consistent with a service or account problem, but it does not claim to provide live Amazon service status.

When should I repair the EPUB?+

Repair the file when the same EPUB repeatedly fails while a known-good EPUB reaches the same account through the same route.
