Hello, I am looking for help on how to make the registered trademark smaller than the rest of my text in our email campaign template. Is this only plausible in the email campaign portion of squarespace? When I select text to be paragraph, or large heading etc, it puts the registered trademark symbol as the same size. I want it to be smaller and preferably in the top right corner of the word. Any help is appreciated! Thank you! -Tina
