Superhuman is a premium email client building a calendar, team comments and AI around its mail core.

Postmark vs Superhuman: editorial side-by-side
Postmark
2.5COMMS
Postmark adds its own SOC 2 Type 2 report to a run of security work.
◆ Current state
Postmark's MCP server has 24 tools and delivery diagnostics, and the team has spent the autumn on account security: webhook verification and monitoring, IP Allowlisting for API sending, and 2FA on the free Developer plan. On November 5 it published its first standalone SOC 2 Type 2 report.
◆ Where it's heading
Postmark is pairing agent-facing tooling (Skills, the MCP server) with the compliance and security controls larger buyers ask for. The SOC 2 report removes a procurement blocker rather than adding a feature.
◆ Prediction
Expect more admin and compliance controls, such as audit logs or SSO, alongside further MCP server tools.
Superhuman
5.0COMMS
Superhuman gives team admins a console and Enterprise a usage report that counts MCP.
◆ Current state
Superhuman is a premium email client building a calendar, team comments and AI around its mail core. October's mobile batch added Compact Mode, swipe actions and attachment-aware AI, and the iOS app now fits iPhone Duo. The newest release adds a team admin console on all plans and an Enterprise-only Team Activity page.
◆ Where it's heading
The product is moving from a single-user power tool toward something a company buys and administers. Seat counts, join approvals, billing and role changes now live in one place, and Team Activity reports which members use desktop, mobile or the MCP and whether they touch AI and collaboration features. That is the reporting a buyer needs to justify renewals.
◆ Prediction
Expect more Enterprise-gated controls built on Team Activity, such as usage-based seat management or policy settings for AI and MCP access. The entries do not show pricing changes, so the timing of any upsell is unclear.
