What causes this error?

Your targeting parameters are mathematically too restrictive. The custom audience size falls below Meta’s absolute minimum threshold required to initiate learning/delivery (usually < 100 people).

How to fix it

1. Broaden your parameters: Add more interests, expand the geographic radius, or increase the age brackets.
2. Check your custom lists: If using a customer CSV upload, realize that only a percentage matches to a Meta user. Ensure your uploaded file has at least 1,000 clean emails/numbers.
