> Suppress records a Suppression for a Contact’s address, which every Startup honors forever.

Suppress records a [Suppression](/business/nouns/suppression) for a [Contact](/business/nouns/contact)’s address, which every [Startup](/business/nouns/startup) honors forever.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `contact` | [Contact](/business/nouns/contact) | Yes | The Contact who opts out. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `contact` | [Contact](/business/nouns/contact) | Yes | The suppressed Contact. |

## Effects
- Emits [`Contact.suppressed`](/business/events/Contact.suppressed).
- Performed by the [Prospector](/agents/sales/prospector).
- Ends every Sequence the Contact is in.
- Keeps the record: suppression is a row, never a delete.

## 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. | [Contact.suppress](/business/nouns/contact/suppress) |

## 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`. |
