The client runs the Ad Manager, a self-service portal for business customers to book and manage advertising products on the GMX and WEB.DE email portals. The Ad Manager is already live and serves as the central platform for campaign management in the B2B sector. There is currently a separate B2B portal called the trusted Dialog Manager, whose features are to be merged into the Ad Manager. Project goal The goal is the technical and functional enhancement of the Ad Manager with features from the trusted Dialog Manager. In the first step, a unified login system will be implemented.
