What is Resend?
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.
What is Stream?
Stream's logistics platform ships steady monthly digests: planning, orders, mobile, no pivots.
This feed is Stream, a delivery and transport-management platform (not the chat/video devtool of a similar name), publishing dated monthly release digests. Each month bundles dozens of scoped improvements across Planning, Orders, Vehicles, the driver mobile app, Public API, and reporting, plus a long fixes list. The cadence is reliable and the work is broad but incremental.

◆ Current state
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.
◆ Where it's heading
Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.
◆ Prediction
Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
Stream
2.5INFRA · APIS
Stream's logistics platform ships steady monthly digests: planning, orders, mobile, no pivots.
◆ Current state
This feed is Stream, a delivery and transport-management platform (not the chat/video devtool of a similar name), publishing dated monthly release digests. Each month bundles dozens of scoped improvements across Planning, Orders, Vehicles, the driver mobile app, Public API, and reporting, plus a long fixes list. The cadence is reliable and the work is broad but incremental.
◆ Where it's heading
The arc is operational maturity, not repositioning: automatic run costing, an Operations Monitor, a rebuilt Clients screen, expanded Public API endpoints and webhooks, and continual planning/mobile refinement. It reads as a maturing vertical SaaS deepening its existing surface for logistics operators rather than opening new categories.
◆ Prediction
Expect the same monthly digest cadence with continued Public API and integration expansion and further planning/mobile polish; no directional shift is visible in these entries.
