Superhuman
Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.
A side-by-side editorial comparison of Courier and Element — release velocity, themes, recent moves, and the top alternatives to consider.
Courier is turning its notification API into a full messaging orchestration platform.
Courier has evolved from a transactional notifications API into an orchestration platform anchored by Journeys, its event-driven workflow engine. Recent releases layer optimization and enterprise controls on top — A/B testing inside journeys, isolated environments, and reusable routing strategies. Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.
Element rebuilds its timeline with MVVM architecture while cutting legacy OS support in v1.12.28.
Element, the open-source Matrix messaging client, ships on a stable two-week release cadence and is currently at v1.12.28. The project is mid-way through a multi-part Timeline MVVM refactor (parts 1 and 2 in v1.12.26 and v1.12.27), restructuring the core room timeline component. The v1.12.28 release raises the minimum glibc requirement to 2.34, ending support for Debian bullseye and Ubuntu releases older than 22.04.

Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.
The build order is clear: ship the orchestration core first (Journeys, Design Studio, the MCP-aware CLI), then make it production-grade for larger teams. The last quarter is about optimization and governance — experiments, custom environments, decoupled routing — rather than net-new channels. AI is being threaded in as a feature, like localization, not a headline product.
Expect continued hardening of Journeys as the hub: more experiment types, richer per-variant analytics, and deeper AI assistance inside Design Studio.

The Timeline MVVM series is the defining architectural investment of this window — replacing the legacy timeline rendering with a proper view-model separation. This is foundational work that typically precedes faster feature delivery on the timeline surface (thread UX, call integration, richer message types). Parallel work promoting Custom Themes to devtools and updating bundle configurations signals cleanup of the extension and theming surface alongside the core refactor.
A Timeline MVVM part 3 or final integration is the immediate next step; once complete, expect improved thread UX or voice/video call timeline integration as the first beneficiaries of the new architecture.
