Superhuman built its name on speed. Split inbox, keyboard shortcuts, AI drafts, and read statuses turned it into the email client that busy executives bragged about. But that speed comes at a price. The Starter plan runs $30 a month, or $25 a month if you commit to a year. The Business plan costs $40 a month, or roughly $33 annually, and that tier is the only way to unlock Ask AI, Auto Drafts, and CRM integrations with HubSpot and Salesforce.
For a solo founder or a small sales team, that adds up fast. $360 to $480 a year per seat is a real line item, not pocket change. And Superhuman still runs on top of Gmail or Outlook, so you are paying for a layer, not a replacement for your existing email provider.
The good news? You have options. Some alternatives match Superhuman's speed for a fraction of the cost. Others go further into AI territory. A few skip AI entirely and focus on privacy or team collaboration instead.
This guide breaks down the best Superhuman alternatives for 2026, what each one actually does well, who should buy it, and what it costs.
Why People Look for a Superhuman Alternative
Before jumping into the list, it helps to know what pushes buyers away from Superhuman in the first place.
- The price feels steep for solo users who just want a faster inbox.
- Some buyers want a native Mac app instead of a browser-based experience.
- Teams need shared inboxes and internal comments, which Superhuman handles differently than dedicated collaboration tools.
- Privacy-focused users want end-to-end encryption, which Superhuman does not offer.
- Gmail-only or Outlook-only users sometimes want a client built specifically for their provider, not a general layer on top of both.
Keep your own priority in mind as you read. The right alternative depends on whether you value price, privacy, team features, or raw AI power.
1. Shortwave: The Closest Feature Match at a Lower Price
Shortwave was built by former Google engineers who worked on Gmail and Google Inbox, and it shows. The app organizes your inbox into bundles, uses AI to summarize threads, and lets you turn any email into a task.
Why buyers pick it:
- AI Assistant that answers questions about your email history, not just individual messages.
- Auto-generated drafts that match your writing style.
- Meeting scheduling and translation built into the AI layer.
- One-click labeling and smart bundling of similar emails.
- Works across web, iOS, Android, Mac, and Windows, all synced to Gmail.
Pricing: Shortwave offers a free plan with 90 days of search history and one connected email account. The Business plan costs $30 per user per month, or $24 per month billed annually, and includes five years of search history. Premier runs $45 per user per month, or $36 annually, with unlimited search history and double the daily AI requests.
Who it fits: People who already love Gmail's Inbox-style bundling and want an AI layer without Superhuman's price tag. Shortwave's free tier alone makes it worth trying before you spend anything.

2. Spark Mail: The Budget-Friendly All-Rounder
Spark, built by Readdle, has been around since 2015 and has quietly become one of the most complete free email clients on the market. It supports Gmail, Outlook, iCloud, and any IMAP account, which gives it an edge over tools locked to a single provider.
Why buyers pick it:
- A genuinely useful free plan with unlimited email accounts and a Smart Inbox.
- Spark +AI for drafting, proofreading, summarizing, and translating email.
- Real-time team collaboration with shared drafts and comment threads.
- Smart Notifications that mute noise and highlight what matters.
- Native apps for macOS, Windows, iOS, and Android.
Pricing: Spark Free costs nothing and covers the essentials. Spark Plus costs $10 per month, or $99 a year, and adds the AI Assistant with a full year of email history, 40 AI meeting notes per month, and advanced productivity tools like Gatekeeper and Smart Folders. Spark Pro costs $20 per month, or $199 a year, and adds unlimited AI meeting notes plus CRM integrations with HubSpot, Salesforce, and Pipedrive.
Who it fits: Anyone who wants a full-featured, no-cost starting point, with room to grow into paid AI features later. Small teams that need shared drafts without paying for a dedicated collaboration platform will also find good value here.
See the full breakdown on the Spark Mail pricing page.
3. Canary Mail: Built for Privacy and Security First
Canary Mail takes a different approach. Instead of leading with AI, it leads with encryption. The app supports end-to-end encryption and PGP, which matters if you handle sensitive client communication, legal documents, or financial data.
Why buyers pick it:
- End-to-end encryption and PGP support baked into the client.
- AI Copilot for drafting and summarizing, but fully optional.
- Read receipts, follow-up reminders, and snooze built in.
- One purchase covers macOS, iOS, Windows, and Android, up to five devices.
- A shared inbox feature for small teams that need lightweight collaboration.
Pricing: Canary Mail Free covers core inbox productivity with unlimited mail accounts. Growth costs $3 a month and adds the AI Copilot, read receipts, send later, and calendar scheduling. Pro+ costs $10 a month and layers on advanced security features and priority support. New users also get a seven-day trial of the paid tiers with no credit card required.
Who it fits: Lawyers, healthcare workers, consultants, and anyone who treats email privacy as non-negotiable. Canary's pricing also makes it one of the cheapest AI-enabled clients on this list.
Details live on the Canary Mail pricing page.
4. Mimestream: The Native Mac Client for Gmail Loyalists
If you live in Gmail and you live on a Mac, Mimestream deserves a serious look. It was built by a former Apple Mail engineer, and it uses the Gmail API directly instead of generic IMAP, which unlocks features other clients cannot match.
Why buyers pick it:
- True label support with synced colors, matching Gmail's web interface exactly.
- Categorized inbox tabs that mirror Gmail's own organization system.
- Signature and alias syncing across devices.
- Fast, lightweight, and built natively in Swift for macOS.
- Support for Google's Advanced Protection Program.
Pricing: Mimestream costs $49.99 a year, or $4.99 a month, for individual use, and that price includes family sharing across up to five devices. Group plans for teams cost the same per seat, with centralized billing. A 14-day free trial requires no credit card.
Who it fits: Mac-only users who want the fastest, most native Gmail experience possible and do not need Outlook or IMAP support. This is one of the cheapest options on this list by a wide margin.
Full pricing is on the Mimestream pricing page.
5. HEY: A Completely Different Philosophy on Email
HEY, built by 37signals, throws out the traditional inbox model entirely. Every new sender gets screened before their email reaches you. Once approved, messages get sorted into the Imbox, Feed, or Paper Trail based on what kind of message it is. There is no algorithmic AI drafting here. HEY is about control, not speed shortcuts.
Why buyers pick it:
- The Screener stops unwanted senders before they ever reach your main inbox.
- Spy pixel blocking stops senders from tracking when you open their email.
- A built-in calendar designed to match HEY's philosophy on focus.
- 100GB of storage and a personal @hey.com address.
- No ads, no data selling, ever.
Pricing: HEY for You costs $99 a year and includes a custom @hey.com address, the HEY Calendar, and 100GB of storage. HEY for Domains, built for companies using their own domain, costs $12 per user per month, with the first user discounted to $10. HEY for Families adds up to four more people for $179 a year total.
Who it fits: People exhausted by spam and tracking pixels who want an inbox that actively defends their attention. It is not built for AI power users, but it solves a different problem extremely well.

6. Missive: The Team Collaboration Powerhouse
Missive is not really competing with Superhuman on speed. It is competing on teamwork. If your business runs support, sales, or client communication through a shared inbox, Missive turns email into a genuine team workspace, complete with internal chat, task assignment, and rules automation.
Why buyers pick it:
- Shared inboxes with internal comments that never leave your email thread.
- Real-time co-editing of drafts, so two people can work on the same reply.
- Support for SMS, WhatsApp, and social channels alongside email.
- An AI assistant and automation rules on higher-tier plans.
- SOC 2 Type II compliance for security-conscious teams.
Pricing: Missive's published plans run $18 to $45 per user per month billed monthly, or $14 to $36 annually. Starter costs $14 a month annually and supports up to five users with unlimited history. Productive costs $24 a month annually and adds rules, AI assistant features, and API access, supporting up to 50 users. Business costs $36 a month annually with unlimited users and advanced security controls like SAML SSO.
Who it fits: Small businesses and support teams that need multiple people working from the same inbox without forwarding emails back and forth all day.

7. Front: Built for Customer-Facing Teams at Scale
Front sits a level above Missive in scope. It is a full customer operations platform disguised as an email client, built for support, sales, and account management teams that need reporting, automation, and omnichannel routing.
Why buyers pick it:
- Shared inboxes with ticket-style assignment and internal notes.
- Omnichannel support across email, SMS, social, and WhatsApp on higher tiers.
- AI add-ons including Copilot, Smart QA, and Smart CSAT.
- Advanced analytics and up to 20 automation rules on the Professional plan.
- SSO and SCIM support for larger organizations.
Pricing: Front runs three tiers billed annually per seat. Starter costs $25 a month and covers one channel type for up to 10 seats. Professional costs $65 a month, supports up to 50 seats, and unlocks full omnichannel support plus advanced analytics. Enterprise costs $105 a month and includes unlimited rules, unlimited workspaces, and the AI features bundled in rather than sold separately. Note that AI add-ons on the Starter and Professional tiers cost extra, so budget accordingly.
Who it fits: Growing support and operations teams that have outgrown a basic shared inbox and need real reporting, SLAs, and automation.
Full plan details are on the Front pricing page.
How to Choose the Right Alternative
With seven solid options on the table, the decision comes down to a few honest questions.
- Are you buying for yourself or a team? Mimestream, Canary Mail, and HEY are built for individuals. Missive and Front are built for teams that share inboxes.
- Do you care more about AI or privacy? Shortwave and Spark lean into AI. Canary Mail and HEY lean into security and control.
- What is your budget? Mimestream and Canary Mail cost a fraction of Superhuman. Front and Missive scale up in price as your team grows, but they replace multiple tools at once.
- Which email provider do you use? Mimestream only supports Google accounts. Spark and Canary Mail work across Gmail, Outlook, and IMAP.
- Do you need a native Mac app, or is a web app fine? If you live entirely inside macOS and Gmail, Mimestream is hard to beat on speed and price.
Final Thoughts
Superhuman earned its reputation, but it is far from the only fast, AI-powered email client worth paying for. Shortwave and Spark come closest to matching its feature set at a lower price. Canary Mail and Mimestream serve users who want speed without the subscription shock. HEY rebuilds the inbox around focus and privacy instead of speed. Missive and Front serve teams that need to work inside email together, not just move through it faster alone.
