Hi, someone on my list has just informed me they have stopped receiving my emails. I notice their email hard bounced in April due to a full mailbox and Hubspot have blocked me emails from being sent ever since. I am unable to unbounce them - there is no option to do this on their contact page - it just says contact has bounced. Any idea how I can get the option to ‘unbounce’ next to the contact?
Hey @BEquine, thanks for reaching out! This is a great question.
From this HubSpot Knowledge Base article on unbouncing contacts:
When a contact’s email address bounces globally, you cannot unbounce them in your HubSpot account. If the email address is legitimate, contact HubSpot support to unbounce them. However, certain bounce types such as unknown addresses and full mailboxes cannot be unbounced because these inboxes are likely abandoned.
It looks like HubSpot does not allow full inbox bounced contacts to be unbounced, though you could still try reaching out to HubSpot support to see if there’s anything they can do.
Otherwise, would it be possible to get an alternate email address from the contact? If the email inbox you were sending to did get full, it doesn’t sound like the contact is actively checking that inbox and would see your emails anyway. Feel free to share with them that you can no longer send to their current email address since HubSpot identified them as being undeliverable. You could let them know that you’ll need another email address that they’re actively using in order to continue receiving your emails.
Hope this helps!!
Hi thanks for the reply - the contact’s inbox became full in April but they increased mailbox space - it is an active account so we need to be able to unbounce the address ideally
Hi @BEquine,
Thank you for reaching out to the Community and thanks a lot @jolle for your help 
Can you please send me in private message the email address of the contact you would like to unbounce?
That way I will check internally for you why it has bounce and if it is possible or not to unbounce.
Thanks a lot!
Have a good day!

Hi there! I am having an issue where a contact has globallly bounced, but I just confirmed his email is correct. Can you help with this?
