Does anyone know what I need to do to my email templates to make the body text responsive for mobile devices? My emails look great on desktop, but on mobile devices, the body copy is small by default and requires the recipient to zoom in.
Is there any basic code I can copy/paste into an email template that will force the body copy to be desvice responsive?
