The Amazon Kindle Publishing Guidelines describes acceptable EPUB content and formatting, but it is incomplete, inaccurate, and some parts do not apply to personal documents.

EPUBs sent via email are passed through Amazon's kindlegen program for conversion to the Kindle formats that will be delivered to the user's devices and apps. That conversion process is less forgiving than the converter built into calibre.

You can try running your failed EPUBs though the Check Book function of the calibre ebook editor or EPUBCheck to look for problems. You can also use Amazon's Kindle Previewer to get Amazon-specific error messages.
