There are two simple and easy ways to transfer the purchased EPUB onto your Kindle.
Use “Send to Kindle”
Go to: https://www.amazon.com/sendtokindle
⚠️ If your Amazon account or your Kindle device are registered in a different country, change the domain extension ending accordingly (e.g., .de, .co.uk, .ca: https://www.amazon.de/sendtokindle)
Log into your Amazon account.
Drag and drop your EPUB file into the upload box.
Switch Add to your library on
Click Send.
It will appear on your Kindle after a few minutes (via Wi-Fi).
Use Send to Kindle for Email
Every Kindle has its own Kindle email address (example: name_123@kindle.com).
Find your Kindle email in your Amazon account:
Click on your account
Scroll down to the section Digital content and devices
Open the link Devices
Click on Kindle
Get the email address linked to your Kindle device
Email the EPUB as an attachment from an approved email address (to get your email address approved, use this guide: https://www.amazon.com/gp/help/customer/display.html?nodeId=GX9XLEVV8G4DB28H)
You can leave the subject empty — just attach and send.
It will sync when your Kindle is on Wi-Fi.
