It works, but it's slow. I emailed one MOBI book to all 3 devices. Each one took nearly 5 minutes to be transfered according to the job list.
Is this normal?
Yes this is normal there is a 300 second delay between sending each book to avoid any spam detection by gmail. You can change that delay by going to Preferences - Tweaks
and changing the The number of seconds to wait before sending emails
tweak. I have mine set to 30 seconds, but rarely use the feature.
