Hi. This is a bit of a long shot but I was wondering if it would be possible to create an email template where a client could edit the background colours of cells by themselves?
Hi WSeddon, welcome to the forums! There isn't a way to do this at present in the template editor, I'm sorry to say. I'll add your vote for it and keep you posted if it's something we add to the editor in the future.
Note that you can change some of the source in the template editor - this may be handy for limited edits, such as highlighting paragraphs.
