Superhuman pushes calendar onto mobile and opens the inbox to AI agents via MCP.
Superhuman is a speed-focused email client now building out two fronts at once: calendar features across mobile (Android calendar, multi-day iOS views, share-availability) and an agentic layer that lets external AI tools drive the inbox through MCP and a Codex plugin. The release cadence is high and split between mobile parity and AI access.
Twilio is hardening messaging into regulated-industry infrastructure — consent, compliance, HIPAA.
Twilio's recent shipping concentrates on compliance and governance rather than new channels: Consent Management and the Compliance Toolkit both became HIPAA-eligible on June 30, Enhanced RBAC reached GA in the new Console, and a white-label compliance embeddable for US A2P 10DLC entered private beta. In parallel it keeps investing in voice AI via a Conversation Relay reference component and pruning legacy API surface (Voice Insights fields, Conference list defaults).

The release cadence is high and split between mobile parity and AI access.
Superhuman is turning its mail client into something AI agents can operate, with search, draft, schedule, send, and triage from Claude, ChatGPT, or Codex, while filling mobile gaps to keep parity with desktop. The bet is that being the most automatable inbox matters as much as being the fastest one.
The next likely move is more MCP-driven capability and continued mobile calendar buildout, extending the Codex/Claude/ChatGPT integration and the new Android and iPad calendar surfaces.

The through-line is making Twilio safe to build regulated, high-volume messaging on — healthcare via HIPAA and signed BAAs, programmatic consent across RCS/SMS/MMS, and ISV-friendly self-service registration. Voice is being repositioned around AI interaction handling. Expect continued regulatory-coverage expansion and further deprecation of pre-Conference-Insights surface.
Next moves likely widen HIPAA eligibility and regional (EU/IE1) availability to more products and push the Compliance Embeddable from private beta toward GA.
