It runs linux so you could in theory run mutt or something like that to get emails in when your on WiFi. I've found with most of the homebrew-y stuff you need to create a launcher that draws the application to the screen of the reMarkable, by default its running a program called xochitl which handles the user interface, file system, etc. So to sum up, doable but not done...yet!
