Superhuman Mail
The fastest inbox with the most convincing personal-voice AI on the market — Ask AI and Auto Drafts genuinely ground answers in your own mail, calendar and the web — but it's a premium per-seat tool from a company that renamed itself after the product eight months ago.
PRICING
| Starter | $25/mo | billed annually ($300/yr); $30/mo monthly; per seat |
| Business | $33/mo | billed annually ($396/yr); $40/mo monthly; adds Auto Drafts, Ask AI, Custom Auto Labels, HubSpot/Salesforce CRM, Superhuman Mail MCP |
| Enterprise | Custom | adds SSO, DLP, BYOK encryption, audit logs, dedicated support |
Prices are for Superhuman Mail specifically. The broader Superhuman Suite (adds Grammarly, Docs, Go) is priced separately with its own Free/Pro/Business/Enterprise tiers.

Strengths
Ask AI is real retrieval-augmented generation over up to five years of email plus live calendar and web lookups, answering in seconds instead of the 15 minutes of manual search it replaces. Auto Drafts 2.0 gathers context across inbox, calendar and web and ships a reply in the user's own voice — Superhuman reports 60% of drafts are sent unedited and 9 minutes saved per draft. The first-party Superhuman Mail MCP server lets Claude, ChatGPT or Cursor act directly on the inbox, with every send gated behind explicit user approval.
Honest dings
Superhuman Mail is priced per seat ($25-40/month) and the deepest AI (Auto Drafts, Ask AI, CRM integrations, the MCP server) is locked behind the Business tier — Starter users get AI writing but not the agentic features. Audit logging is Enterprise-only, so most customers have no visibility into what the AI actually did. The July 2025 Grammarly acquisition and October 2025 corporate rebrand to 'Superhuman' (the whole company, not just the email product) makes vendor identity genuinely confusing, and the underlying model powering Superhuman AI is undisclosed.
