# Email bounced

> Sent when the recipient's mail server rejects an email. The address is added to your suppression list and further emails to it are rejected. Failures caused by the sending side are not reported as bounces.

Sent to the webhook URL configured in your dashboard for emails sent with `Send Email`. Every event is a `POST` with a JSON body, and all events share the same envelope: `id`, `type`, `created` and `data`. `data.message_id` matches the `message_id` returned by `Send Email`.

**Retries:** respond with any `2xx` status within 10 seconds. Otherwise the event is retried 3 more times, after 1, 5 and 15 minutes. Events can occasionally arrive more than once or out of order, so use `id` to ignore duplicates. If an event is missed, `Retrieve Sent Email` returns the email's current activity.



## OpenAPI

````yaml /openapi.yml webhook bounce
openapi: 3.1.1
info:
  title: DeliverymanAI API
  version: 2.0.0
  description: >-
    API documentation for DeliverymanAI. Send emails, track their delivery and
    engagement, read replies, verify addresses, manage your suppression list and
    receive webhook events.


    **Strongly recommended:** leave 5 to 10 minutes between emails sent from the
    same domain. Sending many emails from one domain in a short time can hurt
    your domain and IP reputation.


    **Rate limits:** emails from one sending domain go out at least a minimum
    interval apart. If you send sooner, the email is queued and `Send Email`
    returns `202`. Each endpoint also caps how many requests your account can
    make per minute. Over the cap you get `429` with a `Retry-After` header.
    Treat these limits as an upper bound and keep to the gap recommended above.
