I have implemented a similar service (working from the WWW) that tracks your favourite RSS feeds and sends content to your kindle via their (terrible) sharing email address.
I find it sad that a company with Amazon's reach plays this dirty with what users are allowed to have on their devices. :(
To be honest I'm always surprised how easy it is to put things on your Kindle even if they are not purchases from Amazon. I regularly purchase ebooks some other place and then just send it to the Kindle with Calibre's feature using the amazon sharing email address and it works without a problem for years.
My specific use case is something like the integration that Pocket has with Kobo ebook readers: I see an article I want to read on the internet, I add it to Pocket and then at my next sync I can read it on my device.
An email that Amazon controls is no replacement for a proper API. Having tools to convert to mobi is not a replacement for supporting open ebook formats.
I've wanted to get an e-reader for a while now, but I'd really like to be able to read the articles I have saved in Wallabag[1] on it so I could go fully offline for a day or two a week. One potential solution I saw which is similar to this was wallabag-kindle-consumer[2] but both of this and your solution have issues that dissuade me from them. The first is that I think there's a lot of metadata that isn't encapsulated by both of these solutions. Tagging/highlighting are the first things that spring to mind. The second issue is both are very kindle-specific and I wonder if/how they'd work on a non-Amazon e-reader?
Take my comments with a grain of salt though - I haven't owned an e-reader in years so maybe the interface wouldn't even readily support tagging/highlighting the way I imagine it. I appreciate how simple your solution is and can readily see how it could be extended to support tags at least from the search interface and integrate with other services like Wallabag! Thanks for your work and if I do end up getting an e-reader you'll definitely be seeing some pull requests from me!

Outside of this project you can get tagging with TagSpaces[1] desktop app and highlighting with the SingleFile[2] web-extension.

If the e-reader have a web browser it would work without problems, maybe adjusting css properties a bit.

While KTool is still in active development, feel free to give it a try (no account needed). Much appreciated
The Send to Kindle browser extension is great but it's not really usable on mobile.
With Matter I can add something to my queue while browsing on mobile and from Matter send it to my Kindle already parsed and ready to read.
I use it as a (n effectively) free browser plugin, and also paid for the iPhone app, because it's super-useful to have available there, and also to support the creator - this was something I'd wanted to write for myself and was very glad to not have to.

It's much better than the kindle option where sending the content over email feels like a twenty years step back.
Account closure was due to different reason. Few months back I ordered a phone from Amazon India, but they delivered a perfume. When complained to CS, they closed my account with a vague reason reason that I violated ToS by using a duplicate account. This account closure after I had this account for more than 10 years and have used it in Amazon.com and Amazon.in. Earlier this month, I have a filed a consumer court case (similar to small claims in US) in India.
