Marces William finds Superhuman too costly for personal use and doesn't feel they're getting value for the price, though they would reconsider it for work if security requirements permitted.
Fastest email app – but not a 5 star service, yet
Superhuman is faster than most other apps and the keyboard shortcuts are exceptional, but pricing is high and the lack of unified inbox functionality is a limitation.
Efficient email software for people striving for Inbox-zero.
Superhuman is a pleasure to use with many helpful features. After learning keyboard shortcuts, users can move through emails with ease and mark them done, snooze or set reminders.
