Superhuman

Superhuman is the email client that costs more than most people's streaming subscriptions combined. At $33/month (annual) or $40/month billed monthly for the Business plan, you need a good reason to pay. The reason: speed.

Every interaction in Superhuman happens in under 100 milliseconds. That sounds like marketing, but it's noticeable within minutes of using it. Combined with keyboard shortcuts for every action, power users report saving 3-4 hours per week on email. Whether that math works for you depends on what your time is worth.

The AI features are the newer selling point. Superhuman learns your writing style from past emails and drafts replies that sound like you, not like a robot. Auto Summarize condenses long threads into one-line previews so you can triage your inbox at a glance. Instant Reply suggests one-click responses for common patterns. The AI drafts are good enough that many users send them with minor edits.

Split Inbox sorts email into customizable streams (newsletters, notifications, VIP contacts), which is more useful than it sounds once you stop swimming in one giant inbox. Read Statuses show when recipients open your emails, a feature sales teams love and everyone else finds slightly creepy.

Important pricing change in 2026: Superhuman reorganized into a suite product. The Free and Pro ($12/month) tiers include Grammarly, Coda, and Go, but not the email client. You need the Business plan ($33/month annual, $40 monthly) to get Superhuman Mail. This confuses people who see the $12 price and assume they're getting the email app.

Superhuman works with Gmail and Outlook only. No Yahoo, no ProtonMail, no other providers. The mobile apps exist but don't match the desktop experience. If you live in your inbox and handle 100+ emails daily, the speed advantage is real. If you check email twice a day, spend that $33 elsewhere.
