The following will show email template design from rough sketch to wireframes to complete email examples.
As Box was re-designing their website and brand, they also needed a new look and feel for their email templates.

For our layouts, I wanted content to be interchangeable. We took the approach to construct the emails in modules. If one event or newsletter required more information, the sender could just add another module to fit their needs.
