Hi @Castro,
There isn’t any central notification for bounces.
If you have workflows, you can set up a simple contact-based workflow, triggered by “Email hard bounce reason is known”. You can then add a “Internal email notification” from the right sidebar. Once switched on, this workflow would notify you about new hard bounces.
In this notification, I’d recommend including a link to the contact that bounced. You can use personalization tokens for this. To generate this type link, use this syntax: https://app.hubspot.com/contacts/your_portal_id/contact/personalization_token_for_contact_ID/
Replace your_portal_id with, em, your portal ID, and add the personalization token for “Contact ID” at the end of the link. HubSpot will automatically create the full link in each notification.
Let me know if you have any follow-up questions!
