Verdict

Superhuman at $30/month is excellent if your job is email and you measured the time savings. For most users, Shortwave at $8.50 covers AI-assisted Gmail at a quarter the price; HEY at $99/year offers the most distinctive workflow rethink; Spark Premium at $5/month covers polished mobile-plus-desktop multi-account.

By Subrupt EditorialPublished Reviewed

Superhuman built the fastest email client by treating keyboard shortcuts and AI triage as first-class. The product is well-engineered: the keyboard model removes mouse latency, the AI summarize and reply features are best-in-class for Gmail and Outlook, and the read-receipt model gives accurate context. For users who measured their email-time-per-day in hours and found Superhuman saved 30+ minutes daily, the math at $30/month is honest.

Where Superhuman is shape-mismatched: a user who spends 30 minutes a day in email does not save proportionate time. A user who wants email re-thought from scratch (HEY's screen-the-sender, Imbox/Feed/Paper Trail) is in a different mental model than Superhuman optimizes. A user who wants a unified inbox across Gmail, Outlook, Yahoo, and IMAP wants Spark or Mimestream's territory. The list below addresses those shapes plus the AI-Gmail use case at lower price.

Pick by what email costs you. Heavy AI Gmail user equals Shortwave. Want email rethought equals HEY. Multi-account polished mobile equals Spark. Team-shared inbox equals Missive. Hardcore mac power user equals MailMate.

Our picks for Superhuman alternatives

#1

Shortwave

Free tierLow switching effort

Best for AI-assist in Gmail at a quarter of Superhuman's price

Try Shortwave

Shortwave is built specifically for Gmail and ships AI summarize, AI-driven smart bundles, AI search, and an AI assistant that drafts replies and triages. Personal Plus at $8.50/month is roughly 28 percent of Superhuman's price and covers the AI workflow Superhuman charges $30 for. For Gmail users whose actual want is AI augmentation rather than the keyboard-first workflow, Shortwave is the right shape. The free tier covers basic features for testing.

Strengths

  • +AI-assisted Gmail at $8.50/mo
  • +Gmail-native (no separate sync layer)
  • +Smart bundles auto-categorize
  • +Free tier for testing

Trade-offs

  • −Gmail-only (no Outlook, IMAP)
  • −Less keyboard-shortcut depth than Superhuman
  • −AI usage caps on free tier

  2. Install Shortwave on web, mobile, or desktop and connect Gmail.
  3. Configure smart bundles to match your existing labels.
  4. Test the AI summarize and AI search for two weeks before settling on Personal Plus.

Not for: Skip Shortwave if you use Outlook or non-Gmail providers; Spark or Missive are shaped better.

#2

HEY

High switching effort

Best for email rethought from scratch

Try HEY

HEY (by 37signals) takes the most distinct stance among email clients: every new sender hits Screen The Sender, transactional email goes to Paper Trail, newsletters land in The Feed, and your real conversations live in The Imbox. For users who feel email is fundamentally broken and want a different mental model rather than a faster version of the existing one, HEY is the right call. Personal at $99/year is dramatically less than Superhuman, and the workflow is plainly different. The trade-off: HEY uses @hey.com or your custom domain, not your existing Gmail.

Strengths

  • +$99/year for Personal (vs Superhuman $360)
  • +Plainly distinct workflow
  • +Screen-the-sender stops noise
  • +Paper Trail isolates receipts and notifications

Trade-offs

  • −Requires email migration to @hey.com or custom domain
  • −Workflow takes time to internalize
  • −Limited integration with calendar tools

  2. Set up forwarding from your existing Gmail or Outlook to HEY.
  3. Internalize the Imbox / Feed / Paper Trail mental model over 2-4 weeks.
  4. Migrate fully once HEY covers your daily flow; cancel Superhuman.

Not for: Skip HEY if you cannot change your email address; HEY's full benefit assumes the new address as primary.

#3

Spark by Readdle

Free tierLow switching effort

Best for polished mobile across multiple email accounts

Try Spark by Readdle

Spark by Readdle ships a unified inbox across Gmail, Outlook, Yahoo, iCloud, and any IMAP, with the richest mobile UX in email and a free tier that covers most personal use. Premium at $4.99/month adds AI assist, email translation, unlimited send-later, and unlimited accounts. For users whose inbox spans multiple providers and who want polish on iPhone plus Mac plus Windows plus Android, Spark is the right fit. The price is roughly 17 percent of Superhuman's.

Strengths

  • +Free tier covers up to 5 personal accounts
  • +Premium $4.99/mo across all platforms
  • +AI assist with provider-agnostic support
  • +Cross-platform parity (iOS, Mac, Win, Android)

Trade-offs

  • −Smart Inbox can mis-categorize
  • −Workflow is less keyboard-driven than Superhuman
  • −Some Spark cloud features add a sync layer

  4. Cancel Superhuman once Spark covers your daily flow.

Not for: Skip Spark if you specifically want keyboard-first workflow; Superhuman or MailMate are shaped better.

#4

Missive

Free tierMedium switching effort

Best for shared team inboxes built into email

Try Missive

Missive ships team email collaboration as a first-class feature: chat threads attached to emails, shared inboxes for support@ or hello@ addresses, real-time co-editing of drafts, and shared rules for triage. For teams whose actual problem is not personal email speed but team coordination on shared inboxes, Missive at $14/user/month (annual) is the right shape and Superhuman is not. Free tier covers 3 users for testing.

Strengths

  • +Chat-in-email for team coordination
  • +Shared inbox model for support@ addresses
  • +Real-time collaborative drafts
  • +Free tier for 3 users

Trade-offs

  • −Less polished as a personal email client than Superhuman
  • −Per-user pricing scales with team size
  • −Workflow requires team buy-in

  2. Move support@ or hello@ addresses to Missive shared inboxes.
  3. Configure team rules and chat threads.
  4. Upgrade to Starter once team coordination is dependent on Missive.

Not for: Skip Missive if you only need a personal email client; Spark or Shortwave are shaped better for solo use.

#5

MailMate

Free tierMedium switching effort

Best for Mac power users wanting markdown and IMAP-only depth

Try MailMate

MailMate is a Mac-native IMAP client built for power users who compose in Markdown, want deep smart-mailbox queries, and prefer one-time licensing over subscriptions. The license is $49.99 with lifetime updates within the major version, less than two months of Superhuman. For Mac power users whose email needs are about depth (rules, smart mailboxes, Markdown composing) rather than speed, MailMate fits the workload and Superhuman is not.

Strengths

  • +$49.99 one-time vs $360/yr Superhuman
  • +Markdown composing built in
  • +Deepest Mac-native IMAP feature set
  • +Lifetime updates within major version

Trade-offs

  • −Mac-only (no iOS, no Windows)
  • −UI is utilitarian, not polished
  • −IMAP-only (no Exchange-Web-Services support)

Migration steps

  2. Add your IMAP accounts; MailMate handles standard IMAP only (no Exchange Web Services).
  3. Configure smart mailboxes for the queries that matter (recent, unread per-account, etc.).
  4. Buy the license once MailMate covers your workflow; cancel Superhuman.

Not for: Skip MailMate if you need iOS or Windows support, or if you use Microsoft Exchange Web Services rather than IMAP.

When to stay with Superhuman

Stay with Superhuman if you live in email more than 3 hours a day, you have already internalized the keyboard shortcuts, or your role depends on the inbox latency Superhuman optimizes for. The picks below are honest exits for users who want similar workflow gains at a fraction of the price, or different workflow shapes Superhuman does not offer.

How we picked

Superhuman alternatives are scored on the actual email job that drives switching: AI-assist in Gmail at lower price, distinctive workflow rethink, polished mobile multi-account, shared team inbox, and Mac power-user depth. Each pick leads for one of those.

Pricing is taken from each vendor's site on the review date. The page is reviewed quarterly. Email migration effort is noted explicitly because email moves are higher friction than other tools.

Frequently asked questions about Superhuman alternatives

Is Superhuman worth $30/month?

If you are in email more than 3 hours a day and the keyboard-shortcut workflow saves you 30+ minutes daily, the math is honest. Below that threshold, Shortwave at $8.50 or Spark Premium at $4.99 cover most of the workflow gains at a small fraction of the price.

Does HEY work with my existing Gmail address?

HEY For Work supports custom domains so you can keep your @yourcompany.com address. HEY Personal uses @hey.com unless you bring your own domain. Forwarding is supported but the full HEY workflow assumes HEY as your primary.

What is Shortwave's actual difference from Gmail.com?

Shortwave runs on top of your existing Gmail (it does not replace it); the difference is the AI features (summarize, search, smart bundles) and the workflow polish on mobile and desktop. You can revert to Gmail anytime without data loss.

Can I use Spark on Outlook business email?

Yes. Spark supports Outlook, Microsoft 365, and Exchange. Spark Business at $7.99/user adds team features and SAML SSO for organization-managed accounts.

Is MailMate a good Apple Mail replacement?

MailMate replaces Apple Mail for power users who want IMAP-only depth, Markdown composing, and rules-based triage. It does not replace Apple Mail's seamless macOS integration; for casual Apple Mail use, MailMate's setup overhead is not worth it.
