# Suppressions

The addresses this workspace will not send to.

## Suppressions tools

| Tool | What it does |
| --- | --- |
| listSuppressions | Every address this workspace will not send to, newest first: hard bounces, complaints and the ones blocked by hand. Returned a page at a time. |
| addSuppression | Stop sending to an address. Adding one already listed changes nothing. |
| removeSuppression | Allow mail to an address again. A hard bounce stays. A chat always asks first. |

> Reading needs `settings:read` and changing needs `settings:write`, the scopes the Blocked addresses screen is gated on. The list stops mail from every address in the workspace, so only its owner, through an app that reaches every address, can change it.

> Adding and removing fire the `suppression.added` and `suppression.removed` webhooks, the same as the screen does.
