I am creating a GAE Golang application that will be notifying users of what is happening in the system. Since I want the emails to look nice, I am already using HTMLBody. However, as I'm creating more and more complex emails, I would like to start using something like html/template to crease nice looking emails with CSS and so forth. However, I'm not sure how I can do Template.Execute to turn it into HTMLBody string that can be sent.
How can I use something like html/template to create HTML emails to use with appengine/mail ?
