I created a few different newsletter templates for Inedo, each to fulfill a different purpose.
The Inedo Bootcamp emails are part of the on-boarding process users go through when downloading one of the Inedo products. I provided two options, one is a recognizable newsletter-esq email. The other doesn't fit into MailChimp's normal 640px constraints, and is intended to feel like a tutorial or knowledge based article. The purpose of these emails is for users to learn how to get started with the product.
