What is Courier?

Courier is a unified customer-messaging platform that lets product and engineering teams send notifications and orchestrate lifecycle journeys across every channel — email, SMS, push, Slack, Teams and in-app — from one system. Instead of wiring up each provider and channel separately, teams design and deliver messages through a single API and a visual editor.

What is Courier?

Courier sits between your product and the many services that actually deliver messages, giving you one place to build templates, define routing rules, and orchestrate multi-step journeys. It routes each message to the right channel based on user preferences and business logic, and it works for both human users and, increasingly, AI agents — positioning itself as an "AI-native, agent-ready" notification layer.

Who it's for

Courier serves developers, product teams and growth teams at companies from startups to the Fortune 500, across SaaS, healthcare, fintech and marketplaces. It's for any team that has outgrown hard-coded, one-off notification code and wants a maintainable system for transactional and lifecycle messaging.

Key features

  • Multichannel delivery: email, SMS, push, Slack, Microsoft Teams and in-app
  • Customer Journeys — multi-step workflows triggered by product events
  • No-code visual template editor with multi-channel preview
  • Embeddable in-app inbox with real-time cross-device sync
  • Built-in user preference center for channel and frequency control
  • 50+ provider integrations (SendGrid, Twilio, APNs, Firebase, Slack)
  • Multi-tenant support with isolated templates and data
  • SDKs for React, JavaScript, iOS, Android, React Native and Flutter

One integration instead of many

Courier's core value is consolidation. Rather than integrating SendGrid for email, Twilio for SMS, Firebase for push and Slack separately — then maintaining all of that forever — a team integrates Courier once and routes through its 50+ providers. That removes vendor lock-in and a huge amount of glue code, and it means adding a new channel later is a configuration change rather than an engineering project.

Send the right message on the right channel

Notifications go wrong when everyone gets everything everywhere. Courier's routing rules and built-in preference center let each user control which channels and how often they hear from you, while Journeys orchestrate multi-step, cross-channel sequences triggered by real product signals. The result is timely, relevant messaging that respects user preferences — better engagement and fewer unsubscribes and complaints.

Built for the AI era

Courier leans into AI as a first-class part of the workflow. Frontier models can run as steps inside a journey — scoring users, generating personalized content or enriching profiles — and an MCP server plus developer tooling make it usable by AI agents, not just human-triggered code. For teams building agent-driven products, having notifications that AI can both trigger and personalize is a real advantage.

Developer-friendly and enterprise-ready

Courier ships a CLI, MCP server and SDKs across the major client platforms, plus a production-grade API, so it drops into modern stacks cleanly. Multi-tenant support lets platforms isolate templates, rules and data per customer or brand, and enterprise-grade security and compliance make it viable for regulated industries — so it scales from a first transactional email to a full multi-brand messaging system.

Why choose Courier

For a team that wants to stop hand-rolling notification code and instead manage all customer messaging in one place, Courier is a strong, developer-first choice. Its single API, visual editor, cross-channel journeys, preference management and AI-ready design make it a practical way to deliver the right message on the right channel — and to keep that system maintainable as the product grows.

What is Trigger.dev?

Trigger.dev is an open-source platform for writing background jobs and durable, long-running workflows directly in your codebase, without the pain of setting up and babysitting your own queues, workers and retry logic. You define tasks as normal functions, and Trigger.dev handles reliable execution, automatic retries, durability so a workflow survives crashes and resumes where it left off, scheduling, and clear observability into what ran and what failed.

Its standout strengths are being open source and excellent at long-running tasks. Because it is open source, you can self-host it for full control and data ownership — a real draw for teams with privacy requirements or a preference for owning their infrastructure. And it shines on jobs that take a long time to complete, sidestepping the timeout limits that plague plain serverless functions. The developer experience is polished, with great local development and the ability to write and test jobs naturally, so background work stops being an infrastructure headache and becomes just part of your code.

Trigger.dev is a strong fit for developers and teams who need reliable background processing — sending emails, processing uploads, syncing data, orchestrating multi-step jobs — and who value open source, self-hosting, or running genuinely long tasks. It competes with tools like Inngest in the modern durable-workflow space, with its open, self-hostable nature as a key differentiator. For anyone tired of hand-rolling queues and retry logic, it is a major upgrade that delivers dependable background work with minimal infrastructure to manage.
