Amazon/Kindle
METHOD #1: Transferring files to your Kindle using Email
Download the ePub file to your computer. This will have an .epub extension after the file name and would have been sent to you as an attachment, or if the file was too large for email, you would have been sent a Dropbox link to download the file from. Make sure you know where the ePub file downloads to on your computer (your Desktop or Documents folder may be a good place).
Go to Amazon’s website and log in to your account.
Click on Your Account and then scroll down to the Digital Content section and select Manage Your Kindle or Manage your Content and Devices
Select Personal Document Settings. You should see a heading Send to Kindle email settings. There should be an email address there, XXXXX@Kindle.com.
Go to Approved Personal Document E-mail List section which is further down the page Manage your Content and Devices. Add your email address to this list, so that the Kindle device will accept the file.
In your mail program, start a new email to the @Kindle.com email address you just found.
Attach the ePub file and then send your email.
Wait approximately five minutes and then open your Kindle and sync. Your book should appear in your Books or Documents
METHOD #2: Transferring files to your Kindle using a USB cable
Download the ePub file to your computer. This will have an .epub extension after the file name and would have been sent to you as an attachment, or if the file was too large for email, you would have been sent a Dropbox link to download the file from. Make sure you know where the Mobi file downloads to on your computer (your Desktop or Documents folder may be a good place).
Connect your Kindle to your computer using its USB cable. The Kindle should appear in “Computer” or “My Computer” for Windows users and on the desktop for Mac users.
Open the Kindle drive. You will see several folders. You want to locate the folder called Documents.
Now find the ePub file you downloaded to your computer and copy it to the Kindle Documents folder. You can do that by clicking the file and dragging it to that folder.
Safely eject your Kindle from your computer.
You should now see the Mobi file on your Home screen or in the Documents section of your Kindle.
