A non-endemic advertiser wants to exclude existing customers from their new-to-brand campaign. Which audience solution allows them to do this most effectively?

Advertiser audiences allow non-endemic advertisers to use first-party customer data for activation or suppression in Amazon DSP . This is the most effective way to exclude known customers from a new-to-brand strategy. Suppression helps reserve campaign delivery for potential new customers instead of existing ones. The audience source is advertiser-owned, so it fits brands that may not rely on Amazon retail purchase signals.
