The Best Superhuman Alternatives in 2026 (Fast Email Clients)
Mara Whitfield
Senior tools analyst at Tolodora. Ten years reviewing software so you don't have to sit through 12 free trials.
Superhuman built its reputation on blazing speed, keyboard shortcuts, and a premium feel that turns email into something you fly through rather than dread. It's excellent — but it's also expensive, and plenty of other email clients now offer similar speed, AI features and slick shortcuts, sometimes for free. If Superhuman's price or Gmail/Outlook focus doesn't fit, these alternatives are worth a look.
The clients below all aim at the same goal — help you reach inbox zero faster — but they differ in how they get there: some lean on AI to summarize and draft, some excel at team collaboration on shared inboxes, some are native apps built for speed, and some are simply free. Here's how the best Superhuman alternatives compare.
We rated every pick on four things — pricing and value, functionality, ease of use, and support. Here's the rundown.

Shortwave
- Pricing
- 8.6/10
- Functionality
- 9.2/10
- Ease of use
- 8.8/10
- Support
- 8.4/10
What I like
A fast, AI-first email client built for Gmail — summaries, AI drafting, smart search and keyboard shortcuts.
Best for
Gmail users who want Superhuman's speed with strong AI and a free tier.
Shortwave is the most direct Superhuman alternative for Gmail users. It's fast and keyboard-driven, but its standout is deep AI: it summarizes long threads, drafts replies, and offers powerful natural-language search. With a usable free tier and paid plans below Superhuman's price, it delivers the same fly-through-your-inbox feeling with more AI and less cost.
Spark
- Pricing
- 9.2/10
- Functionality
- 9.0/10
- Ease of use
- 9.0/10
- Support
- 8.4/10
What I like
A polished cross-platform client with AI, smart inbox and a generous free tier across Mac, iOS, Android and Windows.
Best for
People who want a beautiful, free, multi-platform inbox with AI.
Spark, by Readdle, is a superb all-rounder: it works across every major platform, supports multiple email providers, and combines a smart, prioritized inbox with AI writing and summaries. Its free tier is generous and its paid plans are affordable. If you want Superhuman's polish and AI without the price or the single-platform focus, Spark is a fantastic pick.
Missive
- Pricing
- 8.4/10
- Functionality
- 9.2/10
- Ease of use
- 8.4/10
- Support
- 8.6/10
What I like
Team email with shared inboxes, internal chat on threads, and assignment — collaboration Superhuman lacks.
Best for
Teams and support desks handling shared email addresses together.
Missive reframes email as a team activity: shared inboxes, internal comments and chat right alongside message threads, and the ability to assign emails to teammates. It's a category Superhuman doesn't serve. For startups, agencies and support teams handling addresses like hello@ or support@ together, Missive is the standout alternative — and it works for personal email too.
Mimestream
- Pricing
- 9.0/10
- Functionality
- 8.8/10
- Ease of use
- 9.0/10
- Support
- 8.2/10
What I like
A fast, native macOS client built specifically for Gmail, with full Gmail feature support.
Best for
Mac users who want a snappy, native Gmail experience.
Mimestream is a true native macOS app built by a former Apple Mail engineer, designed specifically for Gmail. It's fast, respects Gmail's labels and features, and feels perfectly at home on a Mac — without the heaviness of web-based clients. It's far cheaper than Superhuman, making it a great alternative for Gmail-on-Mac users who prize native speed.
Canary Mail
- Pricing
- 8.6/10
- Functionality
- 8.8/10
- Ease of use
- 8.6/10
- Support
- 8.2/10
What I like
A secure, AI-powered client with encryption, a smart assistant and cross-platform support.
Best for
Privacy-minded users who also want AI email help.
Canary Mail blends AI features (its Sidekick assistant summarizes and drafts) with a strong focus on security, including end-to-end encryption options. It works across platforms and multiple providers. If you like Superhuman's productivity but also care about privacy and security, Canary is a distinctive alternative that covers both.
Gmail
- Pricing
- 9.8/10
- Functionality
- 8.6/10
- Ease of use
- 8.8/10
- Support
- 8.0/10
What I like
The free default — and with keyboard shortcuts, filters and Gemini AI, it's faster than people assume.
Best for
Anyone who wants Superhuman-like speed for free with a little setup.
It's easy to forget that Gmail itself, with keyboard shortcuts enabled, filters, multiple inboxes and its built-in Gemini AI, can get you close to a power-user workflow for free. It won't match Superhuman's polish or single-minded speed, but for many people a well-configured Gmail is the most cost-effective alternative of all — zero dollars and no new app to learn.
The verdict
For an AI-first inbox that rivals Superhuman's speed, Shortwave is the standout (and it's built for Gmail). Want cross-platform polish and a generous free tier? Spark. Need to handle email as a team on shared inboxes? Missive. On a Mac and want a fast native Gmail app? Mimestream. Most of these are free or cheaper than Superhuman, so try one or two — you may get the same speed without the premium price.
Frequently asked questions

Shortwave is the closest in spirit — a fast, keyboard-driven, AI-powered client built for Gmail — and it offers a free tier, making it the top alternative for most Gmail users leaving Superhuman.
Is there a free alternative to Superhuman?
Yes. Spark and Shortwave both offer capable free tiers, and Mimestream (a one-time-feeling subscription for Mac) is far cheaper than Superhuman. You can get much of the speed and many AI features without Superhuman's premium price.
What's the best Superhuman alternative for teams?
Missive is built for team email — shared inboxes, internal chat alongside threads, and assignment of messages — making it ideal for support and shared addresses, which Superhuman isn't designed for.

Mimestream is a fast, native macOS client built specifically for Gmail, and Spark has excellent Mac and iOS apps. Both give you a snappy Apple-native experience.
Do these alternatives have AI features like Superhuman?
Yes — Shortwave and Spark in particular offer AI summarization, drafting and search, matching or exceeding Superhuman's AI features, often at a lower price.
Do they work with Outlook, not just Gmail?
It varies. Spark and Superhuman support multiple providers including Outlook, while Shortwave and Mimestream are Gmail-focused. Check each client's supported providers before switching.
