I have a suggestion for renaming compaign names, if you can add feature like quick edit instead of opening full compaign them edit name but just for renaming not need to open full compaign. so it will be easier to manage and rename quickly when it have quick rename or edit feature.. pls see if you can do this.
Please also enable rename function for a campaign that has already been sent. This existed in the previous version of Constant Contact but doesn't seem to exist in the newest iteration.
