# Send Email Fallback Endpoint

`POST /api/v1/remy/bulk-dm/{job_id}/send-email-fallback`

## Request

- Base URL: `https://api.brandbooster.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.brandbooster.ai/api/v1/remy/bulk-dm/{job_id}/send-email-fallback`
- Auth: HTTP bearer

Email every creator in this job's fallback list; poll GET /email-fallback/status/{job_id} — not the bulk-dm job's id.

  - `attachments` EmailAttachmentDTO[], nullable
    - `filename` string, required
    - `content_base64` string, required
