# List addresses a quality pause flagged

`GET /api/v1/email/campaigns/{id}/quality/affected`

After an automatic quality pause: the recipients whose message hard-bounced (`hard_bounce`) or drew a spam complaint (`complaint`). They're already suppressed; this is for cleaning the source list. By address, `limit` per page (default and most 10,000); when `has_more`, pass the last row's `email` as `after` for the rest. Take them out of the campaign's segment with [Remove flagged addresses](https://www.unitpost.com/docs/email/post-email-campaigns-id-quality-remove-affected). Requires the `campaigns:read` capability.

## Parameters

| `id` | path | string | yes | — |
| `limit` | query | integer | no | Addresses per page, 1–10,000 (default 10,000). |
| `after` | query | string | no | The last row's `email` from the previous page. |
