# Replace audience members

`PUT /v1/admin/email/audiences/{id}/members`

URL: https://docs.spacerun.co/docs/platform/reference/email-audiences/setEmailAudienceMembers

- **Operation ID:** `setEmailAudienceMembers`
- **Tags:** Email audiences
- **Base URL:** `http://localhost:8787`

Replaces the member list with either `members` (emails and/or user ids) or a pasted `csv` (first column; optional `email` header). Duplicates are removed case-insensitively; at most 50,000 members. Invalid CSV rows return 400 `validation_failed` with `invalid_emails` and `invalid_count` in `details`.

**Workflow:** [Integration guide](https://docs.spacerun.co/docs/platform/guides/email-campaigns).

**Authentication:** staff Bearer JWT with permission `email.write`.
