Sent marketing e-mails should show up under the contact record’s Emails tab. Right now we don’t have a way of viewing exactly what was sent to the contacts, thus we don’t have a good way tracking sent e-mails and spotting errors with our personalization tokens.
If it’s too hard to have this done automatically, then at least give us the ability to add a BCC to our marketing e-mails so that we can log them using our personalized hubspot logging e-mail.
