Preparation

1. Kindle with WIFI connection (mine is Kindle Paperwhite 2, bought from Japan)
2. Amazon account (Registered with your kindle; for email sending)
3. IFTTT account (for .mobi, most easy way)
4. Dropbox account (for .mobi)

Why Two Account

Copyright problem

.mobi can be sent by email to amazon account while .azw3 cannot. But why still using .azw3? Because it supports x-ray or Word Wise, which gives you hot highlights and difficult words hints respectively.

Sending ".mobi" Files

Find the Kindle Email Address

Two methods: 1. From Kindle (recommended) 2. From web

From Kindle

Settings --> Device Options --> Personalise your Kindle Then the Email address will show at the bottom.

From web

Here we use the Amazon.com account for example. To know the email addriese, follow the step: Your Account --> Manage Your Content and Devices --> Settings --> Personal Document Settings --> Send-to-Kindle E-Mail Settings

Set Up

Set up IFTTT by creating a folder named kindle in Dropbox and add the Kindle email address to that IFTTT Recipe.

How to Use

Put any .mobi files you want to read to that Dropbox folder. It will sync to your Kindle within 10 minutes.

Sending ".azw3" Files

Put .azw3 files to your Dropbox folder (any folder) and download it from the Kindle browser.
