AMP for Email in Marketo

AMP brings modern interactivity to emails and could really help marketers make their email experiences exceptional. In addition to HTML and plain text, Marketo should also begin supporting text-x-amphtml, the MIME Type for AMP for email. Email clients like Gmail and Outlook.com already support it, and it's rolling out to others too. 

Bonus points if Marketo could integrate with Litmus or get 250ok to support AMP email version previews for testing/QA.
