Hello,
Looks like Delticom has Campaign Classic environments and was integrated with the Experience Cloud for User Management (i.e. IMS Integration). As such, the Campaign login card will be visible online, but it won't serve as a login portal. Only Campaign Standard is accessible through the web and will look like your second screenshot.
To login to Campaign Classic, please download the Campaign Client Console and follow the steps outlined here to login: Launching Adobe Campaign
