What is a suppression list?

A suppression list is the list of an audience for a mobile app or game that advertisers share with an ad network to improve targeting and return on investment (ROI) for user acquisition campaigns.

What types of suppression lists are there?

Static: Lists all device IDs that have previously interacted with your mobile game.

Dynamic: Allows a tracking solution to pass on device IDs that install your mobile game dynamically.

Custom: These lists are used for retargeting campaigns. Ad networks would leverage custom lists to target users who already have your mobile game installed, looking to re-engage them.
