# email.bounced

Event triggered whenever the recipient's mail server **permanently rejected the email**.

## Response Body Parameters

All webhook payloads follow a consistent top-level structure with
event-specific data nested within the `data` object.

- `type` (string) — The event type that triggered the webhook (e.g., `email.bounced`).

- `created_at` (string) — ISO 8601 timestamp when the webhook event was created.

- `data` (object) — Event-specific data containing detailed information about the event. The data object for the `email.bounced` event contains the following parameters:

:::::accordion{title="object parameters"}
* `broadcast_id` (string) — Unique identifier for the broadcast campaign (if applicable)

* `created_at` (string) — ISO 8601 timestamp when the email was created

* `email_id` (string) — Unique identifier for the specific email

* `message_id` (string) — RFC Message-ID header value for the email

* `from` (string) — Sender's email address. For sent events, this matches the value passed at send time and may include a display name (e.g., `Name <email@domain.com>`). For received events, this is the bare email address only; the display name from the original `From:` header is preserved in `headers.from` on the [retrieve endpoint](/guides/receiving-retrieve-received-email).

* `to` (array) — Array of impacted recipient email addresses

* `subject` (string) — Email subject line

* `template_id` (string) — Unique identifier for the template used (if applicable)

* `tags` (Record\<string, string>) — Object of tag key-value pairs associated with the email.

Example:

```json theme={"theme":{"light":"github-light","dark":"vesper"}}
{
  "category": "welcome",
  "user_id": "1234567890"
}
```

- `bounce` (object) — Bounce details from the receiving server

::::accordion{title="bounce object"}
* `diagnosticCode` (array) — Array of SMTP diagnostic responses from the receiving server, including the status code and reason for the bounce (e.g., `smtp; 550 5.5.0 Requested action not taken: mailbox unavailable`)

* `message` (string) — Detailed bounce message from the receiving server

* `subType` (string) — Bounce sub-type (e.g., `Suppressed`, `MessageRejected`)

* `type` (string) — Bounce type (e.g., `Permanent`, `Temporary`)
