As of today, you will be able to see a View Count and Last Viewed Timestamp when viewing Automatic E-mails on the My Sent E-mails page.
To view the screen, go to the Contacts tab and click My Sent E-mails, then select Automatic. From here there will be two new columns of information. The View Count will show how many times a user has clicked to view their newsfeed for the automatic e-mail and the Timestamp will show the last time that newsfeed has been viewed.
