# Suppressions API

> Read and manage the addresses Emailit will not send to.

Base URL: `https://api.emailit.com/v2`. Authenticate with `Authorization: Bearer <API key>`.

## Create a suppression — POST /suppressions

> Add an address to the suppression list, permanently or until a date you choose, so Emailit stops sending to it.

# Create a suppression

Adds an address to your workspace's suppression list. API and SMTP emails to an address with a `recipient` suppression get the status `suppressed` instead of being sent, and campaigns skip suppressed addresses. Requires an API key with `full` scope.

`POST /suppressions`

## Request body

- `email` (string, required): Address to suppress. Emailit stores it in lowercase.

- `type` (string): Suppression type. Default `recipient`. Emailit uses `recipient`, `bounce`, `complaint` and `unsubscribe`. Only `recipient` suppressions stop emails sent through the API and SMTP. Campaigns skip every address with an active suppression of any type. An address can have one suppression per type.

- `reason` (string): Free-text note, for example `manual` or `Asked to stop receiving invoices`.

- `keep_until` (string | number | null): When the suppression expires. Accepts an ISO 8601 timestamp (`2026-12-31T00:00:00Z`), a Unix timestamp in seconds (`1798675200`), or natural language such as `in 30 days` or `tomorrow at 9am`. Omit it or send `null` for a permanent suppression. After this time the suppression stops blocking sends. It stays in the list until you delete it.

## Returns

Returns `201 Created` with the suppression object. Emailit also sends a [`suppression.created`](/docs/webhooks/events/suppression/created/) webhook event.

| Status | When |
| --- | --- |
| `400` | `email` isn't a valid address or `keep_until` can't be parsed (the body has an `error` string), or `email` is missing (standard validation error). |
| `409` | The address already has a suppression of this type. The body includes the `existing` suppression. |

## Retrieve a suppression — GET /suppressions/{id}

> Retrieve a suppression by its ID or by the suppressed email address, including its type, reason and expiry.

# Retrieve a suppression

Returns one suppression, looked up by ID or by email address. Requires an API key with `full` scope.

`GET /suppressions/:id`

## Path parameters

- `id` (string, required): Suppression ID (`sup_…`) or the suppressed address. URL-encode the address, for example `ada%40example.com`. An address can have one suppression per type. When you look up by address, Emailit returns one of them; use the ID to target a specific type.

## Returns

Returns `200 OK` with the suppression object. A suppression whose `keep_until` is in the past no longer blocks sending.

Returns `400` if `id` is neither a `sup_` ID nor a valid email address, and `404` if no suppression matches.

## Update a suppression — POST /suppressions/{id}

> Change the address, type, reason or expiry of a suppression, looked up by its ID or by the suppressed address.

# Update a suppression

Updates a suppression. Send only the fields you want to change; at least one is required. Requires an API key with `full` scope.

`POST /suppressions/:id`

## Path parameters

- `id` (string, required): Suppression ID (`sup_…`) or the suppressed address, URL-encoded (`ada%40example.com`). When an address has suppressions of several types, use the ID.

## Request body

- `email` (string): New address. Stored in lowercase.

## Returns

Returns `200 OK` with the updated suppression. Emailit also sends a [`suppression.updated`](/docs/webhooks/events/suppression/updated/) webhook event.

| Status | When |
| --- | --- |
| `400` | The body has none of the fields above, `email` is invalid, or `keep_until` can't be parsed. |

## List suppressions — GET /suppressions

> List the suppressed addresses in your workspace with search, filters, sorting and page-based pagination.

# List suppressions

Returns the suppressions in your workspace, newest first. The list includes the suppressions Emailit adds automatically after bounces and complaints, and expired suppressions whose `keep_until` has passed. Requires an API key with `full` scope.

`GET /suppressions`

## Query parameters

- `page` (integer): Page number, starting at `1`. Default `1`.

- `limit` (integer): Suppressions per page, from `1` to `100`. Default `10`.

- `search` (string): Case-insensitive match on the address or the reason. `q` works as an alias.

- `match` (string): `all` (default) requires every `key.condition` filter to match. `or` matches any of them. See [Filtering](/docs/api-reference/filtering/).

- `sort` (string): Sort key: `email`, `reason`, `type` or `created_at` (default).

- `order` (string): Sort direction: `asc` or `desc` (default).

## Filters

Filter and sort keys: see [Filtering](https://emailit.com/docs/api-reference/filtering/).

On this endpoint, `order` only accepts `asc` or `desc`. Pass the sort key in `sort`, for example `sort=email&order=asc`.

## Returns

Returns `200 OK` with the suppressions in `data`, plus `next_page_url` and `previous_page_url` (`null` when there is no next or previous page). The page URLs keep your search, filters and sort.

## Delete a suppression — DELETE /suppressions/{id}

> Remove a suppression by its ID or by the suppressed address so Emailit can send to that address again.

# Delete a suppression

Deletes a suppression so the address can receive email again. Requires an API key with `full` scope.

`DELETE /suppressions/:id`

## Path parameters

- `id` (string, required): Suppression ID (`sup_…`) or the suppressed address, URL-encoded (`ada%40example.com`). A request by address deletes one suppression. If the address has suppressions of several types, delete each by ID, or repeat the request until it returns `404`.
