Courier

COMMS
Velocity5.0

Notification infrastructure platform for sending multi-channel messages (email, SMS, push, in-app, chat) through a single API.

Courier is turning its notification API into a full messaging orchestration platform.

messagingorchestrationnotificationsdeveloper-toolsai-featuresenterprise
◆Current state
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.
◆Where it's heading
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.
◆Prediction
Expect continued hardening of Journeys as the hub: more experiment types, richer per-variant analytics, and deeper AI assistance inside Design Studio.

    Experiments: A/B Testing in Journeys

    A/B testing lands directly on journey send nodes, splitting live traffic across up to ten variants and promoting the winner. It is the optimization layer Journeys needed to move from 'send' to 'send the best-performing version' — a sign Courier is deepening Journeys rather than adding new surfaces.

    AI Localization

    AI Translation now lives in Design Studio, localizing templates across email, SMS, push, in-app, and chat in one step. It fits Courier's pattern of threading AI in as a practical feature inside existing tools rather than as a standalone product.

    Embed Notification Preferences with One Web Component

    A single embeddable web component drops a full preferences center — topics, channels, digests, themes — into any app. It extends Courier past sending into the user-facing control surface, cutting the custom UI work customers would otherwise own.

    Introducing Routing: Reusable Strategies for Every Template

    Routing strategies become reusable objects managed separately from templates, centralizing delivery logic across channels and providers. A maturation move that makes multi-provider setups easier to govern as Courier's customers scale.

    Email Fonts and Colors

    Email-safe fonts and background color options arrive in the Courier Designer. Cosmetic polish for brand consistency, not a capability change.

    Custom Environments for Safer Messaging Workflows

    Isolated environments for dev, staging, QA, and production — each with its own keys, data, integrations, and templates — bring standard software-lifecycle hygiene to messaging. A governance feature aimed at larger teams shipping safely.
