Hi,
Some points that will make things easier I feel
(1) Please can work be done to make it easier to see when you have unred emails, the colours are a blend of yellow/green and grey and its very hard to see whats unread, sure you make the row bold but this is not enough.
(2) Its actually very difficult to select and open emails can take many presses sometimes, id also like to see and 'Open' option when you hold your finger down on an email, above the 'Delete' option, this would also help somewhat
