I´d like to suggest that the e-mail sent after the game is finished would contain the black and white ELOs and also the game end date, just like when you click on "get the PGN of all games" at the match page.
I´d also think it would be nice to receive an e-mail when the match ends, so that you can have your progress in that match and also keep track of your improvements.
That´s all
