Heymarket vs Courier: at a glance
What is Heymarket?
Heymarket layers AI agents and routing on top of its business-messaging core.

What is Courier?
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.

Heymarket vs Courier: editorial side-by-side
Heymarket
5.0COMMS
Heymarket layers AI agents and routing on top of its business-messaging core.
◆ Current state
Heymarket is a business-messaging platform expanding across channels (now RCS via Twilio) and into AI agents and workflow features like Escalations. The crawled feed mixes real feature announcements with how-to and thought-leadership content.
◆ Where it's heading
The product is moving from shared-inbox messaging toward AI-assisted, omnichannel operations — RCS, AI agents trained in-house, escalation routing, and structural tools like conversation tags and webhooks. The direction is a fuller customer-messaging operations layer.
◆ Prediction
Expect continued investment in AI agents and channel breadth (RCS, voice) on top of the shared-inbox foundation, likely with more routing and automation controls.
Courier
5.0COMMS
Courier is turning its notification API into a full messaging orchestration platform.
◆ 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.
