Every email that goes out from the Event Hub app is being tracked to:
The email was sent
Confirmation of delivery to the recipient's Server.
If the email has been viewed/opened
If the recipient clicked a link from the EDM.
It should be noted that viewing or opening email is now often blocked by Mail servers for privacy reasons. (Example Apple mail)
As a consequence, EH began tracking option 2 - confirmation of delivery to the recipient's server. This indicates whether the mail at least got the recipient's mail system
You can view this information from any event on the Manage Guest List where emails have been sent to guests.
Email Logs are also now tracked in Event Hub. They are found here./
