I just look at my notifications when I pick up my phone to check what new emails came in, if it's important I'll either reply to it there or if I need to reply later with something I need a PC for I'll leave the notification up so I remember later. I don't have any issue with this and it seems pretty much perfect to me. I don't get the problem.
