Best Practices: mktEditable on non-div elements for emails?
The "mktEditable" class is only supported for <div> elements, and tends to cause problems when used for other elements, so we recommend modifying your template.
So, I saw @Grant Booth mention this in a forum reply a little bit ago and this piqued my curiosity: in the beginning of working with Marketo email templates, I did in fact use separate divs for editable elements but have migrated towards using the class directly on table cells for tidying purposes. Thus far, I haven't seen any issues (if only because the tags operate similarly)—but is this going to cause problems either on Marketo's backend or for users later on?
