Archive Tab
The Archive tab provides a list view of archived campaign results. For events that trigger campaign results archiving, see the description of the Services and Campaigns - Results tab.
Archived campaign results are stored in .ZIP files. To download a selected archive, click Download. To delete an archive that you no longer need, click x.
Storage of archived campaign results is typically defined by the terms and conditions of your service contract. Expired archives are deleted automatically.
Note that all archived campaign results are also deleted automatically when the campaign itself is deleted.
