In that case, I bought a Fire for no good reason. (Unless the restriction I mentioned was previously true and has since been relaxed.)
All your Kindle devices/apps should have an assigned kindle.com e-mail address, which can be found at Amazon: Your Account --> Manage Your Kindle --> Personal Document Settings --> Send-to-Kindle E-mail Settings.
It's only a kindle.com address - there is no distinction for non-kindle devices as the free designation only serves to tell it to only deliver to a kindle device via wifi. It only matters with actual kindle with 3g because of Amazon's document delivery charges over their 3g.
No, not all of my apps have assigned email addresses. Only my tablet was given one. Prior to posting earlier, I set up Calibre to send to that address, tested my Gmail outgoing, then did a news download. Calibre downloaded the news item and sent it. On my tablet, kindle app automatically downloaded the news item and it was ready to read. I also got an email letting me know of the delivery. It worked exactly the same as when I had an actual kindle keyboard.
As I mentioned previously, my phone was never given an email for kindle, but it was installed ages ago and later removed because I can't read on my phone. Too small. You may be right that it's been recently relaxed, as I've had my tablet less than a month so the app install was quite recent.
