MOBI has been deprecated for a long time. Standard formats now are AZW3 (KF8) and KFX. They’re a bit more advanced than MOBI, and thank goodness, since it was a terrible format. AZW3 is essentially a MOBI/EPUB container, and I believe KFX is equivalent to EPUB2, possibly with some EPUB3 features.
Comment on YSK: You don't own your Kindle e-books.

FWIW, Amazon deprecated mobi files recently and epub is the new “sideload” standard. You still have to email the file to the kindle address to be able to read them, or convert to azw3.
If you’re already using Calibre, check out Calibre-Web, which essentially uses a Calibre database as the back end. The interface is so much nicer than Calibre.

You can use an USB cable to upload files to the Kindle, the @kindle email address is just a convenience thing. Calibre is great for converting to a compatible format.

Yeah, AZW3 was the format I was thinking of. For things purchased from the amazon store for the kindle they will be in that format. If you want to move your amazon books library elsewhere you have to use some funky plugins for calibre to convert them to a standard format like mobi or epub
