Meta Custom Audiences

Part of ad audiences. If Meta says coming soon, needs setup, our Meta app isn't approved yet.

Set it up

1. Open Ad audiences and click Connect Meta. Sign in to Facebook with a user who can manage the ad account and approve access.
2. Choose the ad account. Only active accounts you can manage are listed.
3. Accept Meta's Custom Audience terms for that ad account if you haven't. We link to them from the page. Without them, Meta rejects uploads.
4. Create an audience. It appears in Ads Manager under Audiences after the next sync, named as you named it.

Good to know

• We create a customer-list Custom Audience and send SHA-256 hashes of trimmed, lowercased emails. The audience is marked as partner-provided data, because the emails come from WhoLayer, not directly from your customers.
• Meta shows an estimated size range. It needs about 100 matched people before the audience can deliver.
• Meta access lasts about 60 days. We show the expiry date; click Reconnect before then to keep syncing.
• Deleting the audience in WhoLayer deletes it in Meta, and ads using it stop.
