# Admin Email Campaign Backfill

`POST /api/admin/email/campaigns/{campaign_id}/backfill`

## Request

- Base URL: `https://api.sambodh-ias.in` (the document declares no server; this is the origin it was published from)
- URL: `https://api.sambodh-ias.in/api/admin/email/campaigns/{campaign_id}/backfill`
- Auth: none declared

Add recipient rows for eligible users this campaign missed, and send.

Adds rows as 'pending' and re-enters the normal send loop, so backfilled
recipients get the identical body, personalization and unsubscribe handling
as the original run — and the loop's pending-only select means nobody who
already received it can be sent to twice.

## Path parameters

- `campaign_id` string, uuid, required

## Headers

- `authorization` string, nullable

## Request body

- CampaignBackfillRequest
  - `include_joined_after` boolean

## Response `202`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
