In the recent past, we've witnessed a huge increase of internet enabled devices.
The range of device screen size and resolution has widened. So, the email
we design will definitely not look the same in all kinds of devices and email
clients. Now that being so, it is as important to render our email equally good
in all devices and email clients as is designing a creative one. We could easily
accomplish this with responsive designing. Unlike static design, responsive design uses fluid widths for columns, definite style for various viewports and multiple breakpoints.
