Thanks for the reply with screenshots. By "history" I was referring to more than when it was sent, viewed etc. I also wanted to see the body of the email itself...

Looks like this answer is out of date as the interface has changed enough that the steps listed no longer match the UI of QBO.

It would be useful to include screenshots. The written directions don't seem to match the UI of the invoice UI I'm seeing. Maybe the interface has been updated.
