A new feature in the Line Item set up, the ‘Allow for Cookieless Users’ feature will enable impressions to serve to users that may have cookies disabled or for impressions where there is no cookie shared by the publisher. This feature is automatically applied for all CTV, OTT, and In App line items as requiring cookies in these environments may prevent campaigns from serving. It is also recommended to apply this feature for streaming Audio campaigns where cookies are unlikely to be available for targeting.

Including users without cookies will limit the accuracy of frequency caps and conversion tracking when cookies are not available.

For mobile web campaigns, ‘Allow for Cookieless Users’ must be applied to serve to Safari users, as Safari disables third-party cookies by default.
