Do we get notifications when the ads are fully approved?

Unfortunately there is no notification when it is fully approved but you can see the approval status of the artwork in both your Gallery as well as the Artwork section in your campaign dashboard (provided you’ve used that ad/artwork in a campaign). 

I use a modified traffic light system to denote ad/artwork approval status:

• Red - Rejected
• Amber - Pending approval, or partially approved by some of the targeted media owners

Green - Fully approved by both CAASie as well as the targeted media owners.
