Yes, the our email/newsletter templates are fully reponsive.

They will display efficiently on desktop, tablets and mobiles. Both media query and fluid versions are included for all newsletter templates so that you can choose which you want to use.

The media query newsletter templates are the better option but they may not display correctly in some very old email clients and certain webmail clients such as Gmail since media queries are not supported. They should be supported by Yahoo Mail and Gmail soon though.

The fluid version is the most cross-client compatible version and works great with inline styling as well.
