How to find your Kindle email address and approve a sender

Every Kindle, and every Kindle app on a phone or tablet, has its own email address. Anything sent to it — an EPUB, a PDF, an article from a service like ours — turns up in your library. To stop spam, Amazon only delivers mail from addresses you’ve approved. Both settings live on the same Amazon page.

Find your Send to Kindle email address

1. Sign in to Amazon and open Manage Your Content and Devices from your account menu.
2. Open the Preferences tab.
3. Scroll to Personal Document Settings and expand it.
4. Under Send-to-Kindle E-Mail Settings, find your device. Its address ends in @kindle.com.

If you have several Kindles or Kindle apps, each has a different address, so copy the one for the device you actually read on. You can change the part before the @ to something easier to remember from the same list.

Approve a sender

1. Stay in Personal Document Settings.
2. Scroll to Approved Personal Document E-mail List.
3. Choose Add a new e-mail address, type the address, and select Add Address.

Add your own email if you’ll be sending files yourself, plus the address of any service that sends for you. For RSS to Kindle, that’s newpost@rsstokindle.com. Amazon allows up to 15 approved addresses.

If a document doesn’t arrive

• The sender isn’t approved. This is the cause nine times out of ten. Check the exact address, and look for a message from Amazon in your inbox saying a document was rejected.
• It went to a different device. Check you used the address for the Kindle in your hand, not an old one or the phone app.
• The Kindle is offline. Delivery needs Wi-Fi. Amazon keeps retrying for up to 60 days, so it will turn up once the device syncs.
• The file is too big or the wrong type. Email delivery accepts up to 50 MB per message and 25 attachments. EPUB, PDF, HTML, TXT, RTF and common image formats work; MOBI is no longer accepted.

What to send once it’s set up

With the address in hand you can email yourself books with our free EPUB to Kindle tool, pick up free EPUBs from these ten sites, or have the blogs and newsletters you follow delivered every morning.
