Here is a pretty good email client that successfully combines functionality and ease of use. So, most commands are intuitive swipe (if you wish, you can customize them); there is seamless integration with cloud storage: you can upload files directly from Dropbox or Box without downloading it to your device; about the same, you can work with your notes from Evernote. Particularly interesting is the function of the “Like" that allows you to simply notify your companion that you have read his letter.
