This works when you forward single emails manually to the forwarding address - the email is then attached to the corresponding contact.
It does not seem to work in a routing rule set up in Google Workspace which basically forwards all emails sent to a specific inbox to the forwarding address.
A reason might be that the forwarded message header generated by the email client is not present as expected - but that is just a guess, yet.
The HubSpot forwarding address is indeed meant for manual forwarding of 1:1 emails to the CRM as it relies on the message header generated by your email client to log the email on the correct contact record.
The hosted email which you'll forward emails to looks something like this: [username]@[subdomain].hs-inbox.com
The forwarded emails will appear in the conversations inbox, but they'll also be logged on the contact records. If you'd only like to route specific emails to HubSpot, you can configure detailed routing rules in your inbox (like excluding certain email domains from forwarding).
I also wanted to share this Google Workspace help article where Google recommends creating a new email address that will be forwarded and not using a real Google Workspace account or email address.
