You can view all generated registrations (leads) of your advertising campaign in your individual Doorboost advertising account. You can register for this at appnew.doorboost.com/login and find all relevant results of your campaign under Report (click 'View' and the 'Report'). The last section of your campaign evaluation contains all generated registrations.
at the end of your report section, you will find the leads, i.e. the registrations of the interested parties.
You will then be redirected to an external page. There you will find an Excel list of your leads.
