When you use the reply to option in links, you can put a replacement code in the email, and it is replaced correctly; but neither in the subject nor in the body is it taken because it appears outside the platform (it is set up in Gmail, for example).

But the email from the reply to is replaced because it is done on the link itself. It would be nice to be able to implement this same action in the link, for the subject and the body of the email to be sent.
