Superhuman changed how people think about email. It proved that a fast, well-designed email client is worth paying for — The Verge called it "a slick, flashy email app with a cult-like following." But at $25/month per user (billed annually), it's one of the most expensive email clients on the market — and in 2026, you have more options than ever.
Whether you're looking for a lower price, different AI features, or platform support Superhuman doesn't offer, this guide covers the best alternatives available today.
We tested each tool hands-on and compared them across the things that actually matter: AI capabilities, pricing, platform availability, and what makes each one unique.

| App | Price | AI Features | Platforms | Gmail Support | Best For |
|---|---|---|---|---|---|
| Filo | Free (Plus $7/mo annual) | Summary, To-dos, Smart Labels, AI Chat | iOS, Mac, Android, Windows | ✅ | Action-oriented professionals |
| Spark Mail | Free (Plus $10/mo) | AI Compose, Summary | iOS, Mac, Android, Windows | ✅ | Team email collaboration |
| Shortwave | Free (Personal $8.50/mo) | AI Search, Summary, Labels | Web, iOS, Android, Mac | ✅ | AI-first power users |

| Gmail (Default) | Free | Gemini | Web, Mobile | ✅ | If you prefer staying in Gmail |
What to Look for in a Superhuman Alternative
Before diving into specific tools, here's what to consider when switching:
- AI that does more than write replies. In 2026, every email app has AI drafting. Research consistently shows professionals spend 5 to 15 hours per week managing email. The real question is: does the AI help you act on your emails, or just respond to them?
- Price-to-value ratio. Superhuman costs $300/year (Starter plan). That's worth it for some people. But if you're paying for features you don't use, it's not a good deal — it's a habit. It's also worth noting that some alternatives (like Filo and Spark) offer fully functional free tiers — you only pay when you need more.
- Platform coverage. Superhuman now covers iOS, Mac, Android, and web. But not all alternatives do. Check what you need.
- Migration friction. Since most of these tools sit on top of Gmail's API, switching is usually painless. Your emails stay in Gmail — you're just changing the window you look through.
1. Filo — Best for Turning Emails into Action
Pricing: Free / Plus $7/month (billed annually at $84/year) or $10/month (monthly)
Platforms: iOS, macOS, Android, Windows
Best for: Professionals who want their inbox to tell them what to do, not just what to read
What Makes It Different
Here's something important: Filo is completely free for most users. Unlike Superhuman, which has no free tier and requires a paid subscription to use, Filo gives you full access to its core AI features — summaries, to-dos, smart labels, AI chat — at no cost. The Plus plan ($7/month annual) simply increases usage limits for power users who process hundreds of emails daily.
That's a fundamentally different approach. Superhuman is subscription-first: you can't use it without paying. Filo is product-first: use it for free, and upgrade only if you need more.
Filo is what we'd call an action-first email client. Instead of optimizing how you read and reply, it extracts what actually needs to happen from your inbox and surfaces it as actionable items. (We wrote more about this philosophy in Why Filo Isn't a 'Better Gmail'.)
Key Features
Automatic To-do Extraction — This is Filo's headline feature, and no other email client does it. Filo reads your emails and automatically pulls out action items into a to-do list. That meeting you need to schedule? The document you need to review? The deadline that's buried in paragraph three? It's already in your to-do list before you open the email.
AI Summary — Every email gets an automatic summary. Not just a shorter version of the text — Filo extracts key links into clickable buttons (even unsubscribe links buried in footers) and summarizes foreign-language emails in your native language.
Smart Labels — Three default categories (Important, Updates, Marketing) work out of the box. But the real power is custom labels: describe what you want to filter in plain language, and AI handles the rest. It's not keyword matching — it understands context.
Filo AI Chat — Ask questions about your emails, analyze attachments, search conversationally. Think of it as having a research assistant who's read every email you've ever received.
AI Drafts — Tell Filo what you want to say in any language, and it generates a reply matching the language of the original email. Adjust tone, length, or rewrite specific sections.
How It Compares to Superhuman
| Filo | Superhuman | |
|---|---|---|
| Auto To-do Extraction | ✅ Unique feature | ❌ |
| AI Email Summary | ✅ Automatic | ✅ Available |
| Smart Labels/Categorization | ✅ Custom AI labels | ✅ Split Inbox |
| AI Draft in Your Voice | ✅ | ✅ (learns your tone) |
| AI Chat with Inbox | ✅ | ✅ (Instant AI) |
| Keyboard-First UX | Basic shortcuts | ✅ Industry-leading |
| Price | Free (Plus $7/mo annual) | $25/mo annual (no free tier) |
| Security Certification | CASA Tier 3 | SOC 2 Type II |
The Honest Take
Filo isn't trying to be a faster Superhuman. If your primary need is blazing-fast keyboard shortcuts and split-second email triage, Superhuman is still hard to beat. But if you're tired of manually turning emails into tasks, calendar events, and follow-ups — that's where Filo pulls ahead. The automatic to-do extraction alone eliminates one of the biggest daily time sinks — manually turning emails into tasks.
Since Filo is free to start — no credit card, no trial timer — there's zero risk in trying it alongside whatever you're using now.

2. Spark Mail — Best for Team Email Collaboration
Pricing: Free / Plus $10/month ($120/year) / Pro $20/month ($240/year)
Platforms: iOS, macOS, Android, Windows
Best for: Teams that share inboxes or collaborate on email responses
What Makes It Different
Spark's biggest differentiator isn't AI — it's collaboration. Shared inboxes, email delegation, internal comments on threads, and team templates make it the go-to choice for teams that treat email as a group activity. Spark has been around since 2015 and has built a loyal following, particularly among Apple users.
Key Features
- Spark +AI — AI compose, rephrase, translate, and summarize. Solid but not groundbreaking in 2026.
- Shared Inbox & Delegation — Assign emails to team members, comment privately on threads, share drafts before sending.
- Smart Inbox — Categorizes email into Personal, Notifications, and Newsletters. Less customizable than Filo's Smart Labels.
- Email Scheduling & Follow-up Reminders — Set-and-forget scheduling with nudge reminders.
- Multi-Account Support — Works with Gmail, Outlook, iCloud, Yahoo, and any IMAP provider.
How It Compares to Superhuman
Spark is significantly cheaper than Superhuman for teams, and the collaboration features have no equivalent in Superhuman's individual-focused product. However, Spark's AI feels more like an add-on than a core experience — it helps you write, but doesn't fundamentally change how you process email.
Good if: You need team email features. Not the best if you're an individual looking for AI-powered productivity.
3. Shortwave — Best AI-First Email Experience
Pricing: Free / Personal $8.50/month / Business $24/month / Premier $36/month (billed annually)
Platforms: Web, iOS, Android, Mac
Best for: Power users who want the most aggressive AI email automation
What Makes It Different
Built by ex-Google engineers (the team behind Google Inbox), Shortwave treats email like a chat-style interface with AI deeply integrated into every interaction. It bundles related emails automatically, and its AI assistant can search, summarize, and draft across your entire inbox.
Key Features
- AI Assistant — Natural language search and actions across your inbox. "What did Sarah say about the Q3 budget?" actually works.
- Auto-Bundling — Groups related emails (newsletters, GitHub notifications, etc.) into collapsible bundles without manual rules.
- AI Labels & Priorities — Automatically categorizes and ranks emails by importance.
- Markdown Support — Compose emails in markdown with rich formatting.
How It Compares to Superhuman
Shortwave is the closest to Superhuman in philosophy — speed and keyboard-centric design — but with deeper AI integration. The Personal plan at $8.50/month is cheaper than Superhuman, though the Business plan at $24/month is comparable. The main downside: it's still primarily web-based, and the mobile apps feel secondary.
Good if: You want AI that's deeply woven into email, not bolted on. Less ideal if you live on your phone.
4. Canary Mail — Best Budget Option with Privacy Focus
Pricing: Free / Growth $36/year (~$3/month) / Pro+ $100/year
Platforms: iOS, macOS, Android, Windows
Best for: Privacy-conscious users who want AI features without breaking the bank
What Makes It Different
Canary Mail leads with privacy — end-to-end encryption, on-device AI processing, and a Sequoia-backed security pedigree. PCMag noted that it "stands out among email clients thanks to privacy-minded encryption features and built-in AI." The AI features are capable if not spectacular, and the pricing is the most affordable on this list.Key Features
- Copilot AI — Email drafting, summarization, and prioritization.
- End-to-End Encryption — Built-in PGP and SecureSend for encrypted email.
- Read Receipts & Link Tracking — Know when your emails are opened.
- Unified Inbox — Supports Gmail, Outlook, iCloud, Yahoo, and IMAP.
- One-Time Purchase Option — Rare in 2026 — you can buy a lifetime license.
How It Compares to Superhuman
Canary is the budget pick. At $3/month (Growth plan), you get 80% of what most people need from an AI email client. The AI isn't as sophisticated as Superhuman or Filo, but if your needs are straightforward — draft help, summaries, and good organization — it does the job.
Good if: Price and privacy are your top priorities.
5. Mimestream — Best Native Mac Gmail Client
Pricing: $49.99/year (~$4.17/month)
Platforms: Mac only
Best for: Mac users who want a beautiful, fast, native Gmail experience
What Makes It Different
Mimestream is a love letter to macOS. Built entirely in Swift, it uses the Gmail API directly (not IMAP), which means it supports Gmail features like labels, categories, and search operators natively. MacStories called it "the perfect email app for Gmail users on the Mac." It's widely regarded as one of the fastest Gmail clients on Mac.Key Features
- True macOS Native — Built in Swift with full system integration (notifications, keyboard shortcuts, Quick Look, Shortcuts app).
- Gmail API Integration — Labels, categories, and search work exactly like web Gmail.
- Multiple Account Support — Multiple Gmail and Google Workspace accounts.
- Fast. Really Fast. — Opens instantly, searches instantly, scrolls like butter.
How It Compares to Superhuman
Mimestream is Superhuman's opposite in philosophy: no AI, no productivity gimmicks, just a beautifully fast email client. If you love Gmail but hate using it in a browser, and you don't need AI features, Mimestream is the answer.
Good if: You're on Mac, you love native apps, and you don't need AI. Not for you if you want AI-powered workflows or use Windows/mobile.
6. Outlook (New) — Best for Microsoft Ecosystem
Pricing: Free (Copilot requires Microsoft 365 subscription)
Platforms: Windows, Mac, iOS, Android, Web
Best for: Anyone already in the Microsoft 365 ecosystem
What Makes It Different
The new Outlook is Microsoft's unified email client, replacing the legacy Win32 app and Windows Mail. With a Microsoft 365 subscription, you get Copilot integration for AI-powered email features.
Key Features
- Copilot Integration — Summarize threads, draft replies, catch up on long conversations.
- Unified Experience — Same app across all platforms.
- Calendar Integration — Best-in-class calendar built right into the email client.
- Free to Use — The base email client is free; AI features require M365.
How It Compares to Superhuman
Outlook is free and works everywhere, which Superhuman can't match. But the email experience itself is more utilitarian than delightful. Copilot is powerful but generic — it works the same way in Word, Teams, and Outlook. It doesn't feel like an email-specific AI.
Good if: You already pay for Microsoft 365 and want "good enough" AI email.
7. Gmail with Gemini — Best for Staying Put
Pricing: Free (Gemini features rolling out to all users)
Platforms: Web, iOS, Android
Best for: People who don't want to switch at all
What Makes It Different
Google is steadily adding Gemini AI features directly into Gmail — in January 2026, they announced that Gmail is "entering the Gemini era" with AI Overviews, Help Me Write, and Suggested Replies. If you're mostly satisfied with Gmail and just want some AI help, this might be all you need.
Key Features
- Gemini Summarization — Summarize long threads with one click.
- Help Me Write — AI drafting directly in the compose window.
- Smart Reply & Smart Compose — The originals, now enhanced with Gemini.
- Google Ecosystem — Calendar, Drive, Meet — all integrated natively.
How It Compares to Superhuman
Gmail is free and familiar. The AI features are improving but still feel like additions to an existing product rather than a reimagined experience. You won't get automatic to-do extraction, smart categorization, or conversational AI search. But you also won't pay a dime.
Good if: You're fine with Gmail and just want incremental improvements.
The Verdict: Which Superhuman Alternative Should You Choose?
Here's the honest recommendation based on what you actually need:
Choose Filo if you want AI that turns emails into action — automatic to-dos, smart categorization, and AI chat — completely free to start, with a $7/month Plus plan for power users. Best overall alternative for individual professionals.
Choose Spark if you work in a team that collaborates on email. Nothing else matches its shared inbox and delegation features.
Choose Shortwave if you want the most AI-forward experience and don't mind a web-first interface.
Choose Canary Mail if privacy is non-negotiable and you want the lowest possible price for AI email features.
Choose Mimestream if you're on Mac, love native apps, and don't need AI.
Choose Outlook if you're already in the Microsoft ecosystem and want AI included with your existing subscription.
Stay with Gmail if you're mostly satisfied and don't want to change.
Frequently Asked Questions
Is Superhuman worth $25 a month?
For high-volume email users who value speed above all else, Superhuman delivers. But in 2026, alternatives like Filo and Shortwave offer comparable or superior AI features at a fraction of the cost — or even for free. The question isn't whether Superhuman is good — it's whether the $300/year premium is justified when free alternatives with similar AI capabilities exist.
Can I use these alternatives with Gmail?
Yes. Every alternative on this list works with Gmail. Most use the Gmail API or IMAP, so your emails stay in Gmail — you're just using a different interface to access them.
Do I lose my emails if I switch?
No. Since these tools connect to your existing Gmail account, all your emails remain in Gmail. You can switch between tools freely without losing anything.
Which alternative has the best AI features?
For action-oriented AI (turning emails into tasks and workflows), Filo leads. For conversational AI search, Shortwave is the strongest. For AI writing assistance, Superhuman and Spark are both solid. It depends on what kind of AI help you need most.
What's the cheapest Superhuman alternative with AI?
Filo, Spark, and Canary Mail all offer free tiers with AI features — making them technically free Superhuman alternatives. For paid plans, Canary Mail at $3/month (Growth plan) is the cheapest, while Filo's free tier already includes AI summaries, to-do extraction, and smart labels.
