Reviewers largely see Superhuman as a fast, polished email client that helps them clear inboxes quicker, stay organized across multiple accounts, and rely less on the mouse thanks to strong keyboard shortcuts. Many also praise AI features like thread summaries, drafting, and rewriting in their own voice, plus snippets, reminders, split inboxes, and team comments for handoffs. The main complaints are price, a pricing change some users found anti-customer, missing options like a unified inbox or certain add-ins, and a few rough edges on mobile.
