An overview of all active campaigns can be found in the 'Campaigns' menu. New campaigns are marked with a green label on the left side.
In the 'Message Center > News' menu in your account, you can find news items from all the campaigns you have started. Additionally, you will find recent updates, promotions, coupon codes and Daisycon news here. You will also receive a daily and/or weekly news overview by email. You can set this frequency in the main menu under your profile at the top right.
Stop messages from campaigns can be found in the 'Message Center > System Notifications' menu. If you cannot find a campaign in the campaign overview, it is likely that the campaign has been stopped.
