Smartx Mail is clean responsive email template for professional and personal usage. It comes in 6 color themes, 6 layouts each, and 2 backgrounds for each color to choose from (light and dark background).
Smartx Mail uses Media Queries to display nicely on different devices, if the device and the email app you are using support Media Queries the layouts will appear more optimized to the dimensions of the device.
On devices which don’t support Media Queries the email will relay on the device itself to scale its dimensions like the usual HTML email templates.
