I resisted Superhuman for two years because paying $30 monthly for email felt obscene—like buying a $200 hammer when a $15 one drives nails just fine. Then I spent a week processing 150+ emails daily during a product launch, caved and tried it, and genuinely got angry at how much faster everything became. The AI features that recently launched aren't revolutionary, but they're the first email AI I've encountered that actually saves time instead of creating more work.
Superhuman is genuinely the best email experience available, and the AI features are legitimately useful rather than gimmicky—but it's wildly expensive and only worth it if email genuinely dominates your workday. If you're a founder, executive, or sales leader processing 100+ emails daily and you value speed over savings, buy it immediately. Everyone else should try Spark or Shortwave first and upgrade only if you're still drowning.
