The AI Node in Journeys: Smarter Branching, Personalized Messages, and Live Enrichment

Courier Journeys now includes an AI node that you can drop into any customer journey. Use it to branch on logic too nuanced for if/then, generate message copy shaped by each user's context, enrich profiles with live data mid-flow, and batch activity into recurring digests. Existing deterministic journeys keep working. The AI node is additive, not a replacement, and it lets you unlock the kind of personalization that used to require a dedicated ML team. Here's what it does and how to use it.

Your Notification Center, Your Competitive Edge

The in-app inbox is the most valuable notification surface you own. Every other channel has a gatekeeper: push, email, and SMS all run through someone else's filters. The inbox is the one surface where you set the rules. Courier Inbox ships as a drop-in component backed by a hosted API that stores messages, syncs read state across devices in real time, and integrates with your other channels. SDKs for React, Web Components, React Native, Flutter, iOS, and Android. Install it with an AI coding agent or a few lines of code. Theme it, customize the renderers, or go fully headless.

Each section names a specific fix you can apply before you ship the next sequence.

You start with one email provider, add push, then SMS, and suddenly you're maintaining multiple integrations with no shared routing, no preference management, and every copy change requires a deploy. This guide compares five platforms that solve different versions of this problem: Courier for cross-channel messaging with AI tooling, Resend for developer-friendly transactional email, Customer.io for marketing-adjacent journeys, Supabase for built-in auth emails, and Novu for open-source self-hosted infrastructure.
