Unable to send emails.

I am unable to send emails through Hubspot as they keep bouncing back. I have been through this with someone in Sales, have disconnected and reconnected my email, cleared cache and cookies and it is still happening. If I send the emails direct through Outlook, it’s fine. It only happens through Hubspot.
