Test bounce emails not showing up in web hooks

Complex Sailfish

Hi team, 
I used the https://developers.mailersend.com/tools.html to track the bounces and they were not sent to my Webhook (using V1 or V2).
Can you please confirm this is intended? 
We'd like to test email delivery status synchronization, to sync delivery statuses from MailerSend into our system. We need to distinguish between hard bounced and soft bounced emails to correctly set the status on our end and we always receive some unified "rejected" status for those emails via API polling.

Hey Complex Sailfish, thanks for flagging this — super helpful context. We’ll check whether bounces generated via the developer tools are expected to trigger webhook events (v1/v2) and why you might only be seeing a unified “rejected” status when polling the API. We’ll dig in on our side and follow up once we have more clarity.
