How about not placing two divs alongside each other in the first place? Every time I see that, I immediately start looking for the unsubscribe link or mark it as spam.
Your preference is not everyone’s preference. It’s silly to suggest every email client disable media queries because you dislike seeing two elements side by side.
That's true, but is anyone going to be up in arms because things are not side by side in an email?
I agree with others that emails should just be plain text. It has never bothered me or anyone else I've known to just have plain text and a link that sends them to an actual webpage if HTML is absolutely necessary.
