I have seen in the API (end point: http://api.hubapi.com/email/public/v1/subscriptions/) that there is a boolean field named "bounced" that indicates a hard bounce and therefore Hubspot will no longer send to that email address. I have tried to use that field name in a webhook to no avail.
I realize there are other fields such as emailsbounced etc but none of them determine that Hubspot will no longer send emails to it.
What is the field name that indicates an email address that hubspot will no longer send to. In the end Id like to use a webhook to retrieve those in order to remove them from mailing lists.
