Is it safe to use smart quotes in HTML email?
Hello! Years ago when I worked at a different company, I always had to change smart (“curly”) quotes and apostrophes to straight quotes so they would render correctly on all mail clients. My current company uses SFMC (ExactTarget) Content Builder to build emails, and I've never see any rendering issues for smart quotes in my Litmus tests. Is it safe to use both varations of quotes? This topic is surpisingly hard to find best practices for online, so thanks in advance!
