Superhuman Mail is a speed-focused AI email client built around Instant Reply, Auto Summarize, Write with AI and Split Inbox, designed to help high-volume email users fly through their inbox twice as fast as before. It is part of the wider Superhuman suite, under the company formed around Grammarly that also includes Superhuman Docs (formerly Coda). It targets professionals who process large volumes of email and want AI speed features built directly into a premium client. Superhuman Mail is a paid product, with plans starting at $25 per month for Starter and $33 per month for Business; the available pricing information does not confirm a permanently free tier.
Who builds it
Superhuman Mail is developed as part of the Superhuman suite, under the company formed around Grammarly that also includes Superhuman Docs (formerly Coda). That places Superhuman Mail within a broader family of AI writing and workspace products rather than as a standalone, single-product startup.
Core features
- Instant Reply, which drafts three response options overnight so replies are ready when you sit down to your inbox.
- Auto Summarize, which condenses complex email conversations into clear, scannable lines.
- Write with AI, an AI drafting assistant built into composing emails.
- Split Inbox, which separates email into focused views instead of one long list.
- SOC 2 Type 2 certification, giving a baseline security compliance signal for business buyers.
Who it is for
Superhuman Mail fits high-volume email users — executives, salespeople, founders — who want speed-focused AI features baked into a premium client rather than a free, feature-light inbox. Buyers already interested in the wider Superhuman/Grammarly suite, including Superhuman Docs, may value adopting Superhuman Mail as part of that combined ecosystem.
Data and privacy
Superhuman states its plans include SOC 2 (Type 2) certification, which gives business buyers a baseline compliance signal. The available information does not include a specific EU-hosting guarantee or a published AI training-data policy, so DACH teams with strict DSGVO requirements should confirm hosting region and data-handling practices directly with Superhuman before rollout.
Bottom line
Superhuman Mail suits high-volume email users who prioritize raw speed and AI-assisted replies over the lowest possible price, especially given that no free tier is confirmed. SOC 2 certification provides a starting security signal, but specific DSGVO and EU-hosting details should be confirmed directly with the vendor.
