It would be fantastic to be able to see a former email within the system. Right now, you have to copy the email which then saves it as a draft which you then have to delete. If there was a little "view" feature that would bring up a preview of the previously sent email, that would be very helpful.
I've been trying to figure this out for a couple years now! This would be a very welcome function. At least now I know I can do a copy to see it, but just have to remember to go and delete the copy so I don't end up with a bunch of junk draft emails.
