There used to be a way to add my own link into an email newsletter so that my customers could update their profile information. The link at the bottom footer of the emails is tiny, doesn't look great, and I'm not able to add it anywhere else as a call to action in my emails. PLEASE add this link option back to the sign up tools area so that I can put it where ever I need.
Thanks for posting this feedback. At this time, the link in the footer is the only solution available but we suggest encouraging your contacts to click this using directions in your email. Some users even send out a specific email just to ask your contacts to take an acttion for you.
