Superhuman costs $30/month and only supports Gmail and Outlook. Here are the best email clients that deliver AI features, speed, and smart inbox management — many of them free or under $15/month.
Each app below addresses a specific gap in Superhuman's offering. We picked them based on real user review patterns and feature differentiation.
The closest Superhuman competitor on AI features — with natural-language search, thread summaries, smart reply drafting, and automatic label organization. Generous free tier and a fraction of Superhuman’s price on paid plans.
Explore Shortwave data →Automatically sorts email into categories (People, Notifications, Newsletters) so important messages surface first. AI compose, thread summaries, and shared team inboxes round out a polished cross-platform experience.
Explore Spark Mail data →Combines modern AI features (smart compose, summaries, read receipts) with PGP encryption and biometric app lock. Works across iCloud, Gmail, Outlook, and IMAP — broader provider support than Superhuman at a lower price.
Explore Canary Mail data →Built for teams that need to co-manage email. Shared labels, internal chat alongside threads, and collaborative drafting make it closer to a lightweight help desk than a personal email client — ideal for support and ops teams.
Explore Missive data →A fast, open-source desktop client with link and open tracking, snooze, send-later, and unified inbox for any IMAP provider. The Pro plan adds translation, company profiles, and advanced analytics at a very low price.
Explore Mailspring data →Supports Gmail, Outlook, iCloud, and IMAP with a polished desktop interface on Windows and macOS. Calendar, contacts, tasks, and chat are built in. The one-time license means no recurring subscription — the anti-Superhuman pricing model.
Explore eM Client data →We found these alternatives by analyzing review patterns across top email clients and productivity apps. Users switching from Superhuman most commonly cite the high price, limited provider support, and diminishing speed advantage.
If you process 100+ emails daily and value keyboard-driven speed above all else, the time savings can justify it. But for most people, Shortwave or Spark Mail deliver 80–90% of the experience at a fraction of the cost — or free.
Shortwave’s free tier is the closest match — it offers AI search, thread summaries, and bundled inbox organization at no cost. Spark Mail’s free plan also covers smart inbox and basic AI features across all platforms.
No. Superhuman only supports Gmail and Microsoft Outlook accounts. If you use iCloud, Fastmail, Proton Mail, or any standard IMAP provider, you’ll need an alternative like Canary Mail or eM Client instead.
