Every campaign needs to be assigned to groups of your organization.
In order to segment the best way your users fro your next banners, here are the steps:
Create your campaign (My campaigns menu). You can directly assign it to one or more groups.
Make sure that your users are associated with the correct group (My Users menu).
In the My Organization menu, modify your group from the Groups menu of your entity. Then just select the campaign (s) you want.
If you select several campaigns, you have 2 options:
Set up your campaigns to display them in the order of your choice.
Example: Your "Best Wishes" banner will be displayed from January 1 to 31, then make way for the "Product launch" banner from February 1 to 20.
Don't configure your campaigns. Whenever the signatures are updated, Signitic will then randomly affix one of the banners.
