Introducing the AI Node in Courier Journeys

The AI node is a new step inside Courier Journeys that classifies users, branches on the result, and writes per-channel copy from a single prompt. Here's what it does, how to set one up, and when it's worth using over a regular condition node.

Build a Multichannel Onboarding Series in 30 Minutes

A walkthrough of building a four-part multichannel onboarding series (email, in-app inbox, mobile push, and Slack) in 30 minutes: Claude Code and Cowork to orchestrate, Claude Design to mock each channel, Courier Skills to turn mocks into Elemental templates, the Courier MCP server to publish them, and the Courier CLI to send tests. Covers the strategy behind the sequence and how to wire it into a Journey.

Customer Journeys Then and Now

Most customer journey platforms don't use product data. They use marketing data. Open rates. Click-throughs. Maybe a segment based on what plan someone's on. That's not a journey. That's a drip campaign with extra steps. I spent years building behavior-based lifecycle programs at Yahoo. The decisioning was sophisticated. The organizational overhead to ship it was not. The infrastructure layer has finally caught up. Here's what behavior-based journeys looked like then, what most teams settled for, and what's actually possible now.

Journeys: AI-powered orchestration for customer messaging

Journeys is Courier's visual workflow builder for multi-step customer messaging. Orchestrate flows with branching, timing, personalization & built-in AI agents, then deliver across every channel and debug each run node by node.

Introducing Design Studio: a new way to craft customer messages

Introducing Design Studio, Courier’s new multi-channel message builder. Create notifications for email, SMS, push, inbox, Slack, and Teams in one editor with drag-and-drop blocks, HTML support, previews, test sends, and version history.

Notification Observability with OpenTelemetry & Courier (plus Grafana Support)

Courier now exports notification logs and metrics over OpenTelemetry, so teams can monitor delivery, failures, and automation health in Grafana, Datadog, and other observability platforms alongside the rest of their stack.

Help Users Navigate In-App Notifications Faster with Tabs in Courier Inbox

As your product grows, notifications pile up fast—and a single “everything” list turns into noise. Tabs for Courier Inbox let you organize in-app notifications into focused views (like Comments, Mentions, or Reactions) so users can find what they need faster, without you building custom filtering UI.

Your Notifications Now Have Two Audiences: Humans and AI Agents

AI agents are now filtering, summarizing, and acting on notifications before users ever see them. In late 2024, Anthropic released the Model Context Protocol. By mid-2025, MCP had become the connective tissue for AI agents that take actions on behalf of users. Google followed with A2A. Agentic browsers like Perplexity Comet and Opera Neon started treating the web as something to navigate programmatically. Your notification strategy needs to account for machine interpretation, not just human attention.

How to Use WhatsApp Typing Indicators on Twilio (Public Beta Guide)

Twilio now supports typing indicators for WhatsApp. When your backend takes a few seconds to generate a response, you can show users that something's happening instead of leaving them staring at a silent chat. The indicator appears when you call the new /v2/Indicators/Typing endpoint, automatically marks the message as read, and disappears after your response arrives or 25 seconds pass. This guide covers the API details, implementation patterns for Node.js and Python, when to use typing indicators, and current beta limitations.
