BuzzStream can track and add your emails to your contact's records 3 different ways:
1. Automatic Email Tracking
2. BCC BuzzStream using your personal BuzzStream email address
BCC - Every BuzzStream user account has it’s own unique ’BuzzStream email address found in “settings” under the My Info Tab in the Email Tracking Information section. Use this address to BCC the BuzzBox anytime you send out an email. If that email is addressed to a Contact with the same email address in their contact record that email will be added to the Contacts history.
3. Manually adding emails to a contact record.
You can manually add emails to contacts record. When you add the email you'll copy and paste the email body in the notes section. So even if you forget to BCC BuzzStream you'll still be able to make sure your contacts history is complete and up to date with the emails you've sent them.
