I have tried emailing it via the kindle email address as well as the kindle windows utility.
Each of your devices/apps has its own email address so you email directly to your iPad and iPhone, your Kindle email address is only for your Kindle. You can find the addresses associated with each device on your Manage Your Kindle page under Manage Your Devices. If you've emailed a document to one device, that document will be in your Amazon Library (cloud) and you can send it to your other devices from your Library instead of emailing it to each one if you find that easier.
