The "Send to Kindle" has a hard limit of 50MiB if done via Email, or 200MiB if done via amazon.com/sendtokindle.
My complaint on this feature is mostly that the only supported proper ebook format is now epub, and I frequently run into the E999 error. Sometimes I can workaround it by converting the epub to mobi and back, but sometimes it just keeps failing which is frustrating.
(I run Calibre on a Linux headless box in Docker so connecting it to USB then transfer is toily)
