Note: nowadays EPUB is a 'kindle friendly format'. Amazon promised to ditch .mobi support (when sending as e-mail or using Send To Kindle apps) on August. They still work (you will have an e-mail with a warning 'in August 2022 it will be gone', lol), but people are encouraged to use EPUB.
I assume there is some conversion from EPUB to 'new mobi' (azw3 maybe, I forgot the name), but it's on Amazon's side. I've sent 20+ EPUBs via e-mail to my Kindle in the last two months and all of them work like a charm, no problems with formatting and stuff.
Other open source devices like the kobo seem really cool and I'd like to try one but my kindle is still working some years later so it's all I've used.
