    The `email.opened` event is triggered when open tracking records a pixel load.

    ## Event Details
    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 (`email.opened`).

    ### created_at `string`
    ISO 8601 timestamp when the webhook event was created.

    ### data `object`
    Standard outbound email fields. `status` reflects the email log status (usually `delivered` or `sent`), not a separate open status.

    ## Handling this event
    When your endpoint receives an `email.opened` event, you might want to:
    - Track email open rates.
    - Update user engagement scores.
    - Trigger follow-up workflows.
