# Remove flagged addresses from the audience

`POST /api/v1/email/campaigns/{id}/quality/remove-affected`

While a campaign is paused for its delivery quality: take every hard-bounced and complained contact out of its static segment. It edits a reusable segment for good. Each removal records its activity and fires `segment.left` (the first at once, the rest within a few minutes); a repeat removes nothing. A campaign that isn't paused for quality, or a filter (dynamic) segment, is a `409` (a filter's matches can't be removed one by one, and they're suppressed anyway). It doesn't resume the campaign. No body. Requires the `segments:write` capability.
