On a side-note: I'm surprised devices like Kindle survive where superior ones like those from Sony perish simply because of the software walled garden. Not a good outlook for humanity.

What walled garden are you talking about? I never even connected my ~8 year old kindle to the internet, only send files that I own via USB.

I very consciously did not buy a Kindle when choosing an Ereader about a year ago. The Kobo H2O is incredible and has served me very well. The format support is wonderful, and the stock OS does more than I need (though there is a whole community of custom OSes that also look cool). Combined with Calibre, I don't even see what the Kindle value prop is.

If, like me, Amazon dropping support for the MOBI for at was news to you then here is an article discussing the announcement: https://blog.the-ebook-reader.com/2022/05/03/amazon-dropping...

This is just a transfer feature, the deprecation is older as I was already unable to source the official CLI converter a few years ago.

Has anyone had any success sending epub with send to kindle via email? So far since the announcement of them dropping support, I've tried but every time I get a message saying the epub I sent is not in the correct format.

I tried 2 days ago and it worked.

So far the kindle oasis is the best ereader in term of hardware and ergonomy I've used and that's comparing to a kobo sage I also have and to all the ereaders I've had over the years (never had sony but I used to purposefully avoid amazon)

I build a tool to send articles and newsletters to Kindle[0]. I’ve been sending EPUB for a few months and it’s tricky.

Amazon still use the old Kindlegen software and to check if your epub has issues, you need to download their Kindlepreview app and open your epub.

I'm very confused about what file format(s) Kindle actually supports. * They are dropping support for MOBI from their Send to Kindle website and apps. * They are adding support for ePub in their Send to Kindle website and apps, but apparently they will be converted to Kindle format (MOBI? AZW?) under the hood. * Several sites mention AZW3 as the official Kindle format. Is that the same as MOBI? * It is unclear whethe…

Mobi and AZW3 (aka KF8) are both at their core Palm DB files. AZW3 are basically Mobi files for backwards compatibility purposes, with an added compiled ePub file for improved layout options. Kindles can read both formats, with newer Kindles using the HTML/CSS from AZW3 files.

As far as I know, the only options to get an ePub onto a Kindle convert to an AZW3 before putting sending it to the Kindle (or manually convert to a Mobi file before sideloading it). And those conversions aren't perfect, I've absolutely had technically correct ePubs end up as a confused mess when sent to a Kindle. Though, these days most publishers seem to be targeting whatever subset of ePubs Amazon supports in their conversion pipeline.
