Meta Custom Audiences

    Sync your customer base to Meta as Custom Audiences so you can retarget them on Facebook and Instagram, or build lookalikes from your best customers.

    What gets synced

    • Only customers who have opted in to SMS or email marketing.
    • Their email and phone number, normalised and SHA-256 hashed before leaving the platform — Meta never sees raw PII.
    • Audiences can be sourced from a saved Customer List, an RFM segment, a churn band, a manual tag, or all opted-in customers.

    Sync cadence

    Each active audience is refreshed automatically once per day — new opt-ins are added and opt-outs are removed, so your targeting always reflects current consent.

    Setup

    1. Go to Integrations → Meta, enter your Ad Account ID and enable Custom Audiences.
    2. Make sure your Meta access token includes the ads_management scope.
    3. Open Marketing → Meta Audiences and create your first audience.
