URL: /business/nouns/newsletter/delete · Id: `verb:Newsletter.delete` · Call: `await $.Newsletter.delete({ … })` (SDK) or the `do` tool at `https://api.sb/mcp`. Inputs says what to pass, Outputs what returns, When it waits who approves.

> Deletes a Newsletter: a soft delete that keeps its history, undone by `Thing.restore`.

Delete removes a [Newsletter](/business/nouns/newsletter): a soft delete that keeps its history, undone by `Thing.restore`. It is inherited: every [Noun](/business/nouns/noun) has `get`, `list`, `create`, `update` and `delete`.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | `string` | Yes | The id of the Newsletter. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `newsletter` | [Newsletter](/business/nouns/newsletter) | Yes | The Newsletter. |

## Effects
| Fact | Value |
| --- | --- |
| Action class | None: it runs within its seat's Limits |
| Door | Two-way: it runs at once |
| Modes | `try` previews it and stores nothing; `send` returns a pending Action; `do` (default) waits for the result |
| Idempotent | With a key: a repeat with the same `Idempotency-Key` returns the first Action, and a repeat without one runs again |
| Undo | [Thing.restore](/business/nouns/thing/restore) brings the deleted Thing back with its history |
| Emits | `Newsletter.deleted` |

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | None. |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Low: two-way, nothing at stake |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | None: it runs once review passes. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
