Are there any plans for administrator levels. We have staff that we need to access all of our client account, but I would prefer to restrict access to the customization and billing sections - is that possible or planned?
That's not something currently planned for Campaign Monitor - there is just one admin login for each account. We'll add it to our list of requests though as something to consider in the future, if we get more requests.
Yes I'd like to see this kind of feature also - nothing too heavy, just something that might mimic the basic management structure of your usual design agency - a customer, an admin, and a 'super' admin.
I personally (as a manager) don't like the freedom all admins get to edit passwords, billing settings, URL and see markup history. It's not that I don't trust the admins, I'd just rather it never be up for question should there be a mistake.
