Superhuman is a paid email client layered on top of an existing Gmail or Outlook account. It's not a mail server, it's a fast front end for the inbox you already have.
It owns the email client slot, and unlike Mimestream, it isn't tied to one provider or one OS: it supports both Gmail and Outlook, plus web and mobile clients.
Priced for people whose job is largely email, like founders, salespeople, and executives, rather than for a general team chat tool. The Business tier's CRM sync (HubSpot, Salesforce, Pipedrive) is aimed at sales teams specifically.
The real AI feature is Auto Drafts, which writes replies using context pulled from your inbox, calendar, and the web rather than a generic rewrite. There's no permanent free plan, and trial length varies by how you sign up (sometimes 30 days through a referral, sometimes none). Starter runs $30/month or $25/month billed annually; Business is $40/month or $33 annual.
AI-powered email built for high-performing teams.
