Superhuman redefined what a fast email client could feel like. It's also $30 a month, Electron-based, and routes your mail through its own servers. If any of those is a dealbreaker, you have better options than you probably realize.
Six alternatives worth knowing about, ranked by how close they come to replicating what Superhuman does well — without the price, the Electron overhead, or the cloud middleman.
What Superhuman actually gets right
Before the alternatives, credit where it's due:
- A genuinely polished keyboard-first interaction model
- Sub-second perceived responsiveness (though Electron under the hood)
- Good read receipts, send-later, follow-up reminders
- Concierge-style onboarding that actually teaches you shortcuts
- Strong brand, consistent execution
What it gets wrong (for some people)
- Price: $30/month, or $360/year. That's more than most SaaS your whole company pays for.
- Electron: The app is a bundled Chromium. Fast, but never as light as native.
- Cloud dependence: Your email flows through Superhuman's infrastructure. Two parties see your mail, not one.
- No offline story: Superhuman is designed for always-connected use. Local functionality is limited.
The 6 alternatives
1. ZenMail — closest in philosophy, no cloud middleman
ZenMail is the closest philosophical match to Superhuman, built differently. Native Mac in Rust — not Electron. Email stays local in an encrypted SQLite database — no third-party server touches it. The keyboard-first flow is more aggressive: Zen Mode is a full-screen single-thread triage mode, and the Screener holds first-time senders outside the inbox until you approve them.
Under 15MB binary. Sub-100ms cold start. Around 150MB RAM. Currently in private beta in 2026 — free during beta, pricing announced before public launch.
Best for: Superhuman users who love the keyboard velocity but not the price or cloud model.
2. Mimestream — traditional three-pane Gmail client
$50/year. Swift-based, Gmail API, local storage. Keyboard support is present but not the point — the UI assumes mouse-and-keyboard use. If you liked Superhuman for the velocity, Mimestream will feel slower by comparison. See the full Mimestream vs. ZenMail comparison.
Best for: people who want an Apple-Mail-style client with Gmail API support, not a velocity upgrade.
3. Shortwave — AI-first reinvention
Free tier, paid plans for AI features. Heavy on AI summaries, bundles, and AI-drafted replies. Web-first with a Mac wrapper — startup and responsiveness trail native clients. A bet on AI doing most of your triage, not a bet on speed.
Best for: people who want AI doing most of their triage, comfortable with a cloud model.
4. Missive — team-focused collaboration
Subscription starting around $18/user/month. Built for shared inboxes, team chat attached to threads, internal comments. If your team needs to collaborate on incoming email (support, sales), this is the category leader. Overkill for individual users.
Best for: teams collaborating on shared inboxes, not individuals.
5. Gmail on the web + keyboard shortcuts
Free. Enable keyboard shortcuts in Settings and learn the full shortcut map. Under 30 emails a day, this is genuinely competitive — Gmail's search is the best in the business and snooze is native. Biggest weaknesses: speed and no triage mode.
Best for: light users who want zero install and $0 cost.
6. Airmail — the legacy option
Long-standing native Mac client. Handles Gmail and most IMAP accounts. Feature-dense, familiar, but recent development has slowed and the interface feels dated. Included here because it's frequently mentioned in Superhuman alternative discussions.
Best for: existing Airmail users who already paid and are comfortable with it.
Decision framework
What are you really optimizing for?
- Keyboard velocity + lower price + local-first: ZenMail.
- A three-pane Apple-Mail-style client with Gmail support: Mimestream.
- AI-first triage: Shortwave.
- Team inboxes: Missive.
- Zero-cost, light use: Gmail web + shortcuts.
The honest pick
If you're here because you love Superhuman's velocity but can't justify $360 a year or don't want your mail flowing through another server, ZenMail is the answer. Anything else is a step down in velocity for a different set of tradeoffs.
Superhuman is a polished product with a clear price tag. For most people who open this post, ZenMail ships the same velocity without the $360-a-year invoice or the cloud middleman.
