We are trying to find a mobile-responsive newsletter template to use in Marketo. The ones Marketo has available do not work for our needs in terms of layout and design. I uploaded some HTML templates from outside sources into Marketo, but as you probably can guess, the only way to edit them is through the HTML. I am not an HTML expert enough to navigate the vast code and make changes to get the newsletter to look the way we would like.
Does anyone have any advice on being able to edit a responsive template in Marketo? Thanks in advance.
