Hello,
We have great level of expertise in developing fully responsive email templates as we have been working with some affiliate email marketers. Developing an responsive email is different from that of normal html pages because it must be done with inline coding and keeping in mind the constraints from hotmail, gmail and outlook rendering.
We test on multiple devices like: iphone, android mobile, ipad, macbook and windows.
Please feel free to discuss more and we are immediately ready to start the work.
Thanks, Bipul
