I had a case where a contact wanted to change their verified email address. Due to certain medical conditions, this contact cannot accomplish even basic operations most of us take for granted, such as following a link to change their own email address. Because of that, the contact reached out to me to make the change on their behalf. Constant Contact doesn't allow me - the mailing list administrator - to make that change. That's a problem, since it turns out that many of my active subscribers have similar medical issues. I encourage Constant Contact to make some reasonable exceptions for administrators that need to make limited changes to their subscribers' email addresses, especially when it comes to bona-fide issues such as this one. ADA/Accessibility is a real thing in the online world, too, and Constant Contact's voluntary compliance with ADA law in the online world would set a great example. It's a decent trade-off vs strict compliance with best-practice online security, IMHO, AND, if permitted, a manual change by the list administrator in this case also would have the advantage of retaining a contact's engagement history...a benefit that's important when it comes to ADA/Accessibility issues in the real world.
