Reviewers mostly praise Superhuman for speed: keyboard shortcuts, split inboxes, snippets, reminders, and AI summaries or drafting help them clear email faster, stay organized across multiple accounts, and reach inbox zero with less stress. Many also like the clean interface and strong collaboration features such as comments and shared context. The main complaints are price, especially for personal use, plus some friction around mobile interactions, missing features like a unified inbox or certain Outlook add-ins, and concern that recent changes feel more sales-focused.
