As a first step, I would recommend checking to see if your DKIM is successfully connected and using this tool to see if there are any SPF errors.
If you find an error, I would recommend connecting with HubSpot Technical Support, as Support is included in your subscription and they will be able to provide real-time assistance for this matter, where you are able to share screenshots and further information about this.
