What platform does clarity use for autogenerated emails? Should we be building that content and have that setup within our app programming?

We are currently using mailchimp and signed up for their integration partner Mandrill, I love how clarity has such a personal touch with each added question, we are bootstrapping, but does it make sense to add the email workflow into the programming from the start? We are working in a corporate git with CTO team. How does your programmer access the automated content? Can you set that up through a git hub wiki?
