Hubspot has a chrome extension for Gmail where they say you can log your replies to Hubspot. However, when you reply via Gmail, you can only see your reply if you go to contacts and then select the specific contact you have replied to. The reply is not added to the threads you see in your inbox with all of your e-mails.
Hubspot, please add replies sent to contacts via the Gmail chrome extension directly into the e-mail threads in the inbox.
