Sorry Joey, I should have been more specific. 4.0.1.
I’m not using MJML. I tried building the email from scratch in the builder which converts everything to standard HTML tags. Which is what it does with MJML code too. There are text blocks that I specified as white. The background of the container was grey. But when the emails are sent those text blocks were always black. Nothing I tried would fix it. It shows it correctly in the editor window. Just not in the client, Gmail in my case.
Eventually, I just disabled the new editor and built the email out in DW using tables like normal. I limit my designs to 600px wide and can’t be concerned about responsiveness at this point. Email clients are so far behind in what they support it’s best to not get fancy at all.
