Thank you for reaching out to the Community! We understand your concern that you're not making the most out of your lead base. Because email deliverability is a complex topic there can be differences in how ESPs approach deliverability rate protection and bounce policies. One of the protective measures HubSpot has in place is cross-checking deliverability data across different HubSpot accounts: the software will automatically drop contacts from future emails if an email address bounces across three HubSpot accounts. There are a couple of other reasons why a contact may be marked as bounced in HubSpot, you can read more about different bounce errors in this Knowledge base article. The discrepancy with the Unbounce data may stem from the measures HubSpot has in place to protect deliverability rates.
To be able to pinpoint what causes this difference we would need to check the contacts on a case-by-case basis. Our customers can work with Support to understand why a contact is marked as bounced in HubSpot. I would therefore recommend creating a ticket for our Technical Support, including a list of bounced contacts and also the audit you performed in Unbounce.
Please note that the HubSpot platform is not boucing contacts and does not have control over is a message can be delivered or if it bounces. A bounce is a signal from the recipient mail server that the message was rejected within the SMTP exchange. HubSpot is simply displaying the bounce message received from the recipient email server in the HubSpot app.
Even when it comes to UNKNOWN_USER bounces, no email validation vendor is perfect. Contacts marked as deliverabile from a validation vendor may still bounce with an UNKNOWN_USER code attached or for other reasons that cannot be detected by valdiaiton software.
Discrepancy between Hubspot and Debounce deliverability data

This is 100% a thing - I don't trust their automated bounce detection at all - not only is it wrong but there's also no indicator to leverage for segmentation if someone is on the global list.

Our mail domain is not on a blocklist, at least according to the MXToolbox and it is a warmed-up domain.
This situation is affecting a small subset of our CRM. We are constantly sending >200k/mo emails with good open rates (38.47%) and low hard bounce rates (0.07%).
We just want to be sure that we make most of our lead base, I guess as a next step we will reach out to Debounce to understand what might be causing this dicrepancy.

Discrepancy between Hubspot and Debounce deliverability data

Like @karstenkoehler mentioned, was the emails you sent the first emails in a long time?
How many emails did you send? Was it a new email that wasn't warmed up?
Most of the time emails aren't delivered because your ESP flagged your address.
This usually happens because the email wasn't warmed up (IE: You sent a bunch of emails from an email address that is new )
OR because the type of emails you're sending are spam.
If it was an older email address (IE: warmed up) and you aren't sending questionable emails, I would reach out to debounce to see what they recommend.
In extreme cases you may not be able to get unflagged and the solution would be to start over. This has happened to a client of mine before and its no fun. I am sorry this is happening to you.
First of all, sorry to hear this. Definitely a marketer's nightmare.
Was this the first send to all of these contacts after a long time?
Most email validation tools offer certain degrees of convervatism – if that's the case in Debounce as well, what level did you choose? This could've affected the number of bounces. In any case, I'd recommend reaching out to Debounce support about this as well. After all, it might be a bug.
I'd also recommend checking whether your email sending domain has been put on a blocklist. You can do at MXToolbox: https://mxtoolbox.com/blocklists.aspx
These are the steps I would take before thinking about unbouncing any contact in the tool. You're risking damaging your sending reputation further if email these bounced contacts again.
