Hello, I want to send out a broadcast. However, I want the address at the bottom of the email to be listed as the one shown on this page: https://help.convertkit.com/en/articles/2502494-alternatives-for-your-physical-address However, every time I change it, I get a warning that says "Domain has already been taken" and it just reverts back to my original address. I can't find a solution for this anywhere.
