Audience population drops after 30 days for custom CSV uploads

Last update: Thu Dec 11 2025 00:00:00 GMT+0000 (Coordinated Universal Time)

An audience created by uploading a CSV file in Adobe Experience Platform (AEP) can show a sharp decline in qualified profiles after 30 days. This happens because custom audiences have a default expiration period, causing most profiles to expire. Some profiles may remain due to later ingestions or updates from other datasets.

To fix this, confirm the upload date, check the expiration period, and re-upload the CSV file if needed.

Description description

Environment

Adobe Experience Platform (AEP)

Issue/Symptoms

A custom audience generated from a CSV upload initially contains the expected number of profiles (for example, 166k).
After 30 days, the audience count drops sharply (for example, to 26 profiles).
A few profiles remain even after the expiration period.

Resolution resolution

Confirm the date when the custom audience was uploaded via CSV. Refer to Audience Portal Overview in AEP’s Segmentation Service Guide.
Check if more than 30 days have passed since the upload.
If the audience is older than 30 days and shows a reduced profile count, re-upload the original CSV file to create or refresh the audience.
Wait for batch processing to complete and verify that segment membership appears correctly on relevant profiles.

Notes

The expiration period for externally generated audiences is currently set at 30 days.
Remaining profiles may exist because:
- Some IDs were ingested later than the first upload.
- Some IDs have attribute data from other datasets, updating their last qualification time.
There’s no way to query which specific profiles remain after expiration.
