First Email Campaign - "Unknown user" Hard Bounces for Well Known Contacts
We pushed out or first email campaign through HubSpot on September 4th. Didn't really think anything of the bounce rate since they would be filtered moving forward, thought they were once-valid emails that were no longer active.
I received a call today from a coworker saying that our *internal* email addresses could not be sent email to through HubSpot since they hard bounced on the campaign. We send email to each other very often through the CRM and have never had a single issue with bounces between eachother, yet every single one of our addresses bounced. There is also another contact that is highlighted in the image below that we speak with often and have never had an issue.
I did verify that we do not have history with the other redacted contacts in the image below, so I cannot speak to them. I navigated to the help document (https://knowledge.hubspot.com/articles/kcs_article/email/how-can-i-send-an-email-to-a-contact-that-h...) for help on how to unbounce our four internal emails, but we do not have the ability apparently unless we upgrade? We CC each other frequently in the CRM when discussing customers, are we going to be bullied into upgrading just to get that functionality back, or is there another way to unbounce our addresses?
Thank you for your help,
