@lenoxbrown I had the same idea, adding the address to the list of users, but has that actually worked for you? The emails get recorded in SMARSH? Our rep here says that CUNA does not find this sufficient because the sent from email is an issue.
We have SMARSH integrated with our Outlook client and I am looking into the Outlook and HubSpot integration to see if that might help us a bit. Have you looked into it? HubSpot Marketplace
It seems to me, at this time, the only thing we can do to be compliant is to create the emails in HubSpot and export te HTML and send them from Outlook which is not great
