I tried it several times, but Amazon says it cannot convert nor delivery files of such type (but only Mobi, Doc, Docx etc.).Įdit: Maybe I should have mentioned that I live in Brazil, and my Kindle is registered here: I'm not sure if that's relevant, but perhaps that's why I could sent Azw3 via e-mail. Now, - at least since today, when I noticed it, - I am not able to do it anymore. In fact more than half of all my Kindle library is made of Azw3. That’s saying nothing of innovations like color e-ink and stylus support.Have you been having any problem lately sending Azw3 to Kindle via e-mail? I was able to do it with no problem at all at least till Sep 6, which was the last time I sent an Azw3 to Kindle via e-mail. These more versatile devices generally run Android, meaning that they can access Kindle libraries via Amazon’s app on top of easily loading up DRM-free files. Meanwhile competitors like Onyx, Xiaomi, and Pocketbook have been offering tons of new tech and form factors. Kindle models have iterated in teeny-tiny increments for years, only gaining USB-C charging support on the latest models. This is entirely speculative on my part, but it seems to me that the widening market of ebook readers is making Amazon sweat a little. Amazon announced support for ePub files in the Send To Kindle and Kindle Documents Service earlier this year. An analogy might be the Sony-branded MP3 players from the early 2000s which didn’t actually play MP3s, instead insisting users convert all their music to the proprietary ATRAC format.

Kindle refusing to allow easy use of the most common open digital book standard was a glaring downside to Amazon’s mostly-closed system.
