Trying to use Marketo <meta> variables (mktomodulescope) hidden from the editor.
I'm trying to use the Marketo variables to stylise the email template, without relying on css classes. The problem is that defining these variables and using them to dictate things like border widths, border radius' means they are editable as local or global variables in the Marketo email editor. The mktomodulescope attribute is boolean and only supports 'true' or 'false'. Does anyone know how I can keep the variables working in the background, but not include them as local or global variables?
