Hello there! The link is not broken in general. I received your email yesterday at 9:38pm MDT containing the word "testing." (I also received the personal email at 9:20pm MDT.) Can I ask what you did differently between the "testing" email and the "testing2" message shown in your screenshot?
I do see that the Feedback module's formatting is a little messed up (the header should not be left-floating.) I can definitely get that fixed (I know why it's happening) and I'll look into it when I have time.
