Ink is a responsive email framework, used to make HTML emails look great on any client or device. It includes a 12-column grid, as well as some simple UI elements for rapid prototyping.
Ink is MIT-licensed and absolutely free to use. Ink wouldn't be possible without the support of the entire ZURB team, our friends and colleagues who gave feedback, and some luminaries who did some heavy lifting that we took advantage of (thanks guys).
Ink was made by ZURB, a product design company in Campbell, CA.
