Bring lists you already own into the platform.
Supported sources
- Customer lists — upload a CSV file (for example hashed emails or device IDs).
- Customer data platforms — Segment and other CDPs, through the Audience Import plugin.
- The AdTech Europe DMP — build audiences from visitors, customer lists, converters and engagers and use them across programmatic, search and social. See What is the DMP?.
One-off or refreshed
A list can be imported once, or kept current: imported audiences are matched and refreshed daily. Refreshing matters most for suppression lists, which go stale quickly — an out-of-date customer list means you start paying to re-acquire recent buyers.
How to import
- Create a new audience with Import as its source.
- Upload your CSV, or connect your CDP.
- Once processed, the audience is available in every campaign.
Your data stays yours
Audiences belong to the account that created them and are never shared with other advertisers.
Compliance note: you are the controller for data you import and are responsible for having a lawful basis and appropriate consent for it. See GDPR: who is the controller?.
