Send to Kindle Not Working: How to Fix [2023]

Kindle may be many things, but the ability to read and download books from the internet via the Send to Kindle feature is a blessing. But what if this feature no longer works?

I, too, had to deal with this issue many a time, may it be as a result of network issues or due to irregularities with the E-mail registration.

Here are the many fixes to resolve this issue on your Kindle.

If Send to Kindle is not working, first, check the status of your network. Second, ensure that the email address employed is registered and approved on Amazon. Additionally, check the file type. If the issue persists, downgrade your Kindle firmware or factory reset the Kindle device.

Check the Status of the Network

Check the Status of the Network

The most probable cause for the Send to Kindle feature to not work is if your Kindle device does not have an active internet connection.

As a result, the sent email with the contents won't reach your device.

This issue is usually a glitch resulting from a bad wireless connection.

Usually, the book will download with a second attempt. Be patient, set the device down, and check it again after 10 to 15 minutes.

Amazon servers are often bogged and need some time to process your request.

Additionally, you should also check if your Kindle device is in 'Airplane' mode. Users often turn on Airplane mode to conserve battery by reading books offline on Kindle.

Alternatively, you can check your content library to know if the book is visible.

If you are sure that you are connected to the internet and have not yet received your books even after waiting for a reasonable period of time, you should check your internet connectivity.

Try connecting another device to your network and check if that device has access to the internet.

Restart the Router/Modem

Router unplugged

Restarting the router/modem is a step you can do to unclog your network from any issues it is having.

Doing so will refresh the system internals and obviate any temporal issues that may be causing networking issues on your Router.

Refreshing the Router/Modem also happens to be an effective fix for resolving issues with Kindle Unlimited.

To restart your Router/Modem, follow the steps below:

  1. Power off your modem (and Wi-Fi router if separate).
  2. Disconnect the power cord and let the device idle for at least 2 minutes.
  3. Reconnect the power cable and wait for all the LED indicators to stop blinking.
  4. Try connecting your Kindle to check if network issues are resolved.

If you are still unable to connect to the network even after restarting the router/modem, try forgetting the Wi-Fi network on your Kindle device.

Rescan to connect once again to your Wi-Fi network to restore functionality.

In the absence of a stable network connection, you also won't be able to connect to the Kindle store.

Ensure Your Email Address is Registered and Approved on Amazon

Send to Kindle

To use the Send to Kindle feature, you need to have an email ID approved by Amazon.

Here's how you would normally send a document to your Kindle via the Send to Kindle feature:

  1. First, add the sender's email address to your approved personal document email list in the 'Manage Your Content and Devices' section.
  2. Check if the document type is supported by Amazon Kindle.
  3. Attach the document to the email.
  4. Press Send.

This is the conventional way to send content to your Amazon Kindle via email. However, there are a few things in between that can go wrong.

Since you are unable to send your books via email, the first check is to verify if your email ID is indeed on the list of the approved personal document email list.

To check the email addresses associated with your Kindle device, follow the steps below:

  1. Log into your Amazon account and go to the 'Content & Devices' settings tab.
  2. Click on the 'Devices' tab. Here, you should be able to see the Kindle device.
  3. On selecting the Kindle device, you will see the email address associated with the device.
  4. Ensure the email address you are sending the books to is the very same one in the approved list.

To reiterate, the email ID that is in the approved list should be filled in the recipient field of the email that you compose.

If you have received your device as a gift from someone who has been using it before, chances are that the Kindle is not registered to your account.

It could be that the previous owner has not yet deregistered the Kindle from their Amazon account. Or it could also have been done to give you access to the books already purchased under the account.

When you buy a Kindle E-reader, oftentimes, the device will be registered to the Amazon account used to purchase the device. So make sure you keep this in mind if you have received your Kindle as a gift.

Use Another Email Address

Using another email address rather than the one you have been using is known to be an effective remedy for this glitch.

If you have been successfully sending books via email before and are unable to now, it could be that your email address got removed from the approved list.

So make sure you check if the email address is still valid in your registered Amazon account or create a new one and add it to your account.

Check the File Type

Check the File Type

Another possible reason why you are not receiving your books could be due to the file type you are sending the content in.

Amazon Kindles are programmed to accept only certain file types. For example, books in the ".epub" or ".kfx" formats are not recognized by the Kindle.

A list of file types that can be read by the Amazon Kindle is given below.

File TypeExtension
Microsoft Word.DOC, .DOCX
Kindle Format.MOBI, .AZW
File Formats supported on Kindle

If you happen to send a file belonging to a format other than the ones mentioned above, your Kindle may not be able to recognize the same.

Ensure the File Doesn't Exceed the Size Limit

Another parameter you need to abide by when you send books over email to your Kindle device is the number of files and their size.

You are allowed to send a maximum of 25 books or files in one go to your Kindle email address. This is unaffected by any compression (like .zip or .rar) you have done.

The total number of books across all of your bundles should not be greater than 25.

Just like the limitation on the number of books, the maximum size of the books or content that you can send to the Kindle in one go is 50 MB.

To clarify, this does not mean that each file should be less than 50 MB but rather the cumulative size of all files that you send via a single email should be less than 50 MB for the Kindle to read the email properly.

This is where compressing files can be useful.

If you have compressed any files, Kindle will automatically unzip the archived books and show each document independently.

If you have not met any of these criteria, the email will not be successfully read by your Kindle.

Downgrade the Kindle Firmware Version

Downgrade the Kindle Firmware Version

If you have recently upgraded your Kindle software, bugs or glitches in the newer firmware could be causing the emails to not be read.

Upgrading the software may help fix issues such as the Kindle Store unavailable. But for this issue, you may have to do the opposite.

If Send to Kindle has stopped working since you last updated your Kindle, try downgrading your Kindle firmware to the previous version.

You will have to look up the version of your Kindle device. Search for the previous software and install it on your Kindle device.

The drawback to this method is that to successfully downgrade your firmware is quite a task and you need to be tech-savvy to do this.

Not to mention that you'll have to jailbreak your Kindle to downgrade the software. And for sure, this is risky business. A wrong step and you might brick your Kindle.

However, there is no guarantee that this will fix the problem. So execute this fix at your own peril.

Factory Reset Kindle

If none of the solutions in this article has yielded any results, then it is time to factory reset your Kindle. Make sure you have tried all other troubleshooting methods before you factory reset.

A factory reset will erase all personal data and downloaded content returning your Kindle to factory default settings.

So before you do the factory reset, try if a simple soft reset can fix your issue. To do a soft reset of your Amazon Kindle, follow the steps given below:

Kindle Power Button
  • Press and hold the power button of your Kindle device till a dialog box appears or the screen goes blank.
  • Keep the power button pressed and do not let go for approximately 40 seconds and then let go.
  • In a few seconds, the charge indicator light should turn on and the device will reboot.
Kindle Restarting

Check if the content you sent via email is accessible now or try resending the email.

To Factory reset your Amazon Kindle, follow the steps below:

1. From the Kindle home screen, swipe down to access 'Quick Actions' or open 'Menu'.

Kindle All Settings tab

2. Navigate to 'Settings' and open 'Device Options'.

Kindle Reset option

3. Tap on 'Reset'. For older devices, you should tap 'Reset Device' again.

4. A prompt will ask you to confirm. Tap on 'Yes'.

When the process is complete, your device is deregistered from Amazon. You need to set up your device as you did when you used your Kindle for the first time.

Factory resetting could also come to your rescue if your Kindle becomes slow.

Final Thoughts

The Kindle, unlike the Fire tablets (another Amazon offering), is purely meant for reading, and that too, it does so wonderfully. And so, encountering such issues on this device can infuriate the best of us.

From scouring through user forums, this issue seems to be a bug in the software. However, you should wait for some time for the books to arrive.

There have also been some recent changes to the process of sending books via email to Kindle.

You might be receiving a confirmation email to the primary email account registered with Amazon to receive the documents send to the Kindle email address.

Check to see if you have got such a mail. Check under the spam section as well. This is a step that is easy to miss as you might not be aware that you need to approve the confirmation email.

If you are unable to find a fix for this frustrating issue yet, contact the Amazon support team for personalized suggestions.

Hope the solutions outlined in this article have helped you to restore the functionality of your Kindle.

Have a Good Day!
