If this is the first time someone has emailed you their book as an .epub or .mobi file, then chances are that you may be a bit confused as to how to move the file from your inbox to your device.
Below are links to guides we’ve found for various situations.

.mobi is the format used by the Amazon Kindle reader (the device as well as the app that you can load on your smartphone or tablet).
Perhaps the easiest way to get a .mobi file into your Kindle is via email.
