Fan of inbox zero? Maybe some minimalism? Like Medium as a writing tool?
Bearing in mind it was only released a week ago, CloudMagic for Mac is already a serious candidate for your desktop mail client. Loves = the attachment view (visual sorting + click to Quick Look!), the gorgeously simple ‘Compose’ window (with rich formatting options), and the blazingly fast interface (sorry, Mail). Plus, the developers comprise a visionary team, so you can comfortably expect great things to come!
Here are my suggestions for improvement, some which may or may not be already on the developers’ “to do” list:
• Improve Split View. At the time of this writing, the CloudMagic window takes up the vast majority of the screen, making multitasking impossible. I tend to use my mail client in tandem with Wunderlist for easy task management and delegation; options like these are currently unavailable to users. Gimme that responsive window, yo!
