Even with JS code in an HTML mail within a browser, cross domain policies are 
still enforced.

I would recommend reading up on cross domain policies, it is going to be a lot 
more helpful than you trying to guess what is going to happen when someone 
receives an email. There are very specific requirements that have to be met for 
a cross domain GET request to fetch data and allow the page it is being loaded 
into to use said data.
