Can't recommend Foundation for Emails highly enough for rendering html. I found it super easy to use (Moustache templates) and very flexible for managing multiple versions (translations) of a newsletter.
The assignment I had was to write, coordinate translations, produce and send a quarterly newsletter with anywhere between 20 and 35 translations per issue + optional separate content to be included on a country-to-country basis. Production time from drafted newsletter to final send was about 2 weeks.
The Foundation tool felt to me a little like jekyll for email. I had a a lot of fun with it.
