Everything that would stop this campaign sending, as a list of checks, the same set the dashboard shows before you press start, and worth calling before [`POST /campaigns/{id}/start`](https://warmerly.com/docs/campaigns/readiness-check#start-a-campaign) so a failure is explained rather than guessed at.

```json
{
  "ready": false,
  "checks": [
    { "key": "has_steps", "label": "Message sequence has at least one complete step", "ok": true },
    { "key": "senders.email", "label": "At least one email sender connected", "ok": true },
    { "key": "plan_gates.send_limit", "label": "Monthly campaign send limit not reached", "ok": true },
    {
      "key": "sender_identity",
      "label": "Sender postal address set for the email footer",
      "ok": false,
      "severity": "warning",
      "detail": "Campaigns send without one, but the footer won't carry it."
    },
    { "key": "leads", "label": "At least one lead queued to receive the sequence", "ok": false, "detail": "Add at least one lead" }
  ],
  "usesEmail": true,
  "usesLinkedin": false
}
```

A check with `severity: "warning"` does **not** block sending, `ready` can be `true` with warnings present (starting then needs `acknowledgeWarnings`, see [Start a campaign](https://warmerly.com/docs/campaigns/readiness-check#start-a-campaign)). Anything without it is a blocker. Further copy and deliverability checks appear in the list too, such as `merge_tags`, `brief_for_opener`, `lead_research`, `deliverability` and `content_quality`. Unlike `start`, this call does not run the live AI provider check. For a draft with no senders it also attaches the project's healthy mailboxes that can send campaigns. The `usesX` flags say which channels the sequence actually uses, so a LinkedIn-free campaign is never held up by a LinkedIn check.
