I added a comment with some example HTML. The email to my colleague contained the HTML all nicely formatted as if I had hand-rolled that HTML for the email. I’m guessing this shouldn’t happen.

we need to take the escaping from the Send Email action, and apply it here instead…!

Hello Colman, Thank you very much for reporting this issue. We’ve fixed it and will deploy it in the coming days.
