I am working on a email template in which I wants to create a three columns grid structure for desktop and single column structure for mobile devices, I don't want to use the media query because it is not supported in android devices. Is there any way to achieve this ?
Anshul, Media queries are supported on Android as long as you use table stacking and not TD stacking. More on that here: https://www.emailonacid.com/blog/article/email-development/how_android_is_strangling_responsive_design
Your other option, which will make it work everywhere, is to use fluid-hybrid design: http://webdesign.tutsplus.com/tutorials/creating-a-future-proof-responsive-email-without-media-queries--cms-23919
