Is there a way to create an audience of ECNs that were a part of a different audience in the last 30 days

Hi @nickmannion ,

You can use Journey Canvas with a streaming audience trigger to capture Audience A qualification and make it usable for Audience B exclusion:

Step 1: Create a Journey for Audience A Qualification

• Entry condition: Audience Qualification (Streaming Audience) for Audience A.
• This ensures the journey starts as soon as a profile qualifies for Audience A.

Step 2: Capture Qualification on the Profile

• Inside the journey, add:
  • Update Profile Activity
    • Set a flag like audienceAQualified = true.
    • Add a timestamp audienceAQualifiedDate = current date.
  • Custom Action (Optional but Recommended)
    • Create a custom action that sends an event to AEP, e.g.:
      {

      "eventType": "AudienceAQualification",

      "timestamp": "<current date>",

      "audienceId": "AudienceA"

      }
    • This event becomes part of the profile’s experience events, giving you historical context for segmentation.

Step 3: Build Audience B

• In Segment Builder, define Audience B with exclusion logic:
  • Exclude profiles where audienceAQualifiedDate is within last 30 days
    OR
  • Exclude profiles that have the custom event AudienceAQualification in the last 30 days.

This approach ensures:

• Real-time qualification is captured immediately.
• You have two ways to reference historical membership: profile attribute or custom event.
• Audience B can reliably exclude anyone who qualified for Audience A in the last 30 days.

Thanks a lot.
