Superhuman and Spike both want to make email faster, but they disagree on what ‘faster’ actually means. Superhuman says faster is zero lag and keyboard shortcuts on a Mac. Spike says faster is rendering email as chat bubbles so short back-and-forths feel like iMessage. After three weeks on the same account, the winner comes down almost entirely to how long your typical threads are.
The One-Sentence Verdict
Go with Superhuman if your day is filled with long, formal threads with clients and investors. Go with Spike if your team lives on two-line replies and wants team chat and video calls folded into the same app for $6/user/month.

What Each One Actually Is
Superhuman
Superhuman is a VC-backed email client out of San Francisco that rebuilt the Gmail and Outlook experience from scratch. It bills itself as the fastest email experience in the world, and after three weeks of daily use I kept landing on the same word: instant. The Mac and iOS apps are mature; Windows and Android are newer but catching up. It’s not a team help desk and not a calm-inbox reset tool—it’s a precision instrument for people who plow through hundreds of emails a day.
- Split Inbox auto-separates team, VIP, and tool mail
- Built-in AI: Auto Summarize, Instant Reply, Auto Drafts, Auto Archive
- Command palette and keyboard-first flow (n, e, r, s)
- Integration sidebar: Slack, Notion, Linear, Figma, GitHub, Calendly
- Read receipts, scheduling, recurring reminders, snooze
| Plan | Price |
|---|---|
| Starter | $25/mo annual ($300/yr) or $30 monthly |
| Business | $33/mo annual ($396/yr) or $40 monthly |
| Enterprise | Custom pricing (SSO, security, dedicated success) |
Spike
Spike is a client that re-renders email as instant-message bubbles. It bundles team chat, one-click video calls, and Magic AI into one cheap cross-platform app. The bet is that most business email is really just short back-and-forths that feel wrong in a threaded list. It works beautifully for casual, fast exchanges and falls apart on long, formal multi-recipient threads.
- Chat-style conversation view
- Built-in team chat and one-click video calls
- Magic AI for summarising, drafting, translating
- Priority Inbox and cross-platform apps
- Cheap Pro tier (~$6/user/mo)
| Plan | Price |
|---|---|
| Free | $0 — one account, 1 GB storage, limited Magic AI, Priority Inbox |
| Pro | ~$6/user/mo annual — up to 3 accounts, 5 GB, unlimited Magic AI, priority support |
| Ultimate | ~$12/user/mo annual — unlimited accounts, 20 GB, advanced customization |
| Team | ~$4/member/mo annual — team chat, shared inbox, video, 100 GB/member |
Where Superhuman Wins
I ran both clients on a 14,000-email archive. Superhuman handled long client threads—the kind with 30 messages, attachments, and five CCs—as a clean, scannable list. Spike re-rendered the same thread as chat bubbles, which meant scrolling past 20 one-line replies to find the original attachment. On a formal thread, that’s actively harder to read. Superhuman’s keyboard flow also won: I could archive, snooze, and reply without touching the trackpad, and the integration sidebar opened the matching Linear ticket.
On G2, Superhuman users call it ‘ridiculously fast,’ and the concierge onboarding gets repeated praise. The cost is $300/year and a two-week learning curve. If you’re not a keyboard person, you’re paying for something you’ll never fully use.
Where Spike Wins
Spike won on the short stuff. When a colleague sent ‘lunch at 12?’ and I replied ‘sure,’ the chat-bubble view made the exchange feel like texting instead of a formal thread. The built-in team chat meant I didn’t have to context-switch to Slack, and the one-click video call worked when we needed to talk. The free tier is genuinely usable for one account, and Pro at ~$6/user/month is a fraction of Superhuman’s price.
The caveats are real. Spike’s own Capterra reviews note gaps in calendar and meeting-invite handling—I saw a meeting invite land without a button to accept it. Pro caps the unified inbox at three accounts and 5GB of storage. And the AI is shallow: Magic AI summarizes and drafts, but there’s no auto-archive, no auto-labels, and no auto-drafts like Superhuman has.
The Price Math
Solo user (1 person, 1 year)
Superhuman: Superhuman Starter annual: $300/yr. Built-in AI, shortcuts, integrations — $300/yr.
Spike: Spike Pro annual: ~$72/user/yr. Or $0 on the free tier for one account — $0 (Free) / ~$72/yr (Pro).
Verdict: Spike is $228/year cheaper than Superhuman for a solo user. If your email is short and chatty, that is a clear win. If you live on long formal threads, Superhuman’s readability is worth the gap.
Team of 5 (1 year)
Superhuman: Superhuman Business for 5: $33/mo × 5 × 12 = $1,980/yr. Plus Slack (~$6.67/user/mo) for internal chat: ~$400/yr more. Total ~$2,380/yr — ~$2,380/yr (Business + Slack).
Spike: Spike Team for 5: ~$4/member/mo × 5 × 12 = $240/yr. Includes team chat, shared inbox, and video calls—no Slack needed — ~$240/yr (Team x5).
Verdict: Spike Team is roughly $2,140/year cheaper than Superhuman + Slack for a five-person team, because it absorbs the chat and video tool. The trade-off is that long formal threads get harder to read.
Pros & Cons
Superhuman Pros
- Blazing speed—zero lag even with 10,000+ emails; ‘fast’ is the most-cited word on G2.
- Split Inbox automatically separates team, VIP, and tool notifications with zero manual triage.

- Strongest integrations sidebar in the market—Slack, Notion, Linear, Figma, GitHub, Calendly.
Superhuman Cons
- Expensive: $25–$40/month—one Capterra user called it ‘a bit expensive considering it is basically a front-end for Gmail.’
- Steep shortcut learning curve; G2 new users say the first two weeks require the onboarding to click.
- Deep CRM integrations (Salesforce/HubSpot/Pipedrive) are gated behind the Business tier.
- Team features are lightweight; no full shared inbox, assignment, or internal chat for large teams.

Frequently Asked Questions
Is Spike a real shared inbox?
Sort of. The Team tier adds a shared inbox and team chat, but there’s no ticketing, no SLA, and no assignment queue. For a real help desk, use Front or Missive.
Does Superhuman have chat bubbles?
No. Superhuman is a traditional threaded list, by design. It’s built for scanning long threads quickly, not chat-style exchanges.
Which is cheaper for a small team?
Spike Team at ~$240/year for five people is dramatically cheaper than Superhuman Business at $1,980/year—and that’s before you factor in Slack.
Can I use both at once?
Yes—both are clients on top of Gmail/Outlook. You could run Superhuman for formal client mail and Spike for internal team chat, though that sort of defeats the point.
