Notifications Landscape

How to Send Notifications from an AI Agent with Courier's MCP Server

AI agents handle support tickets, monitor pipelines, run onboarding flows, and sync CRM data. When they do, someone needs to know what happened. Courier's MCP server gives agents direct access to the full notification API: send across email, push, SMS, Slack, and in-app. Check user preferences before sending. Trigger batch and digest Journeys so high-volume agents don't spam users. This guide covers MCP server setup, CLI tooling, Courier Skills for your IDE, and five real-world patterns with starter prompts.

Customer Engagement Platforms Are Splintered. Message Orchestration Is the Fix

Customer engagement platforms are splintered. Some are built for campaigns, others for support automation, and others treat messaging as a transactional delivery problem. The result is collisions, blind spots, and message fatigue. The highest-leverage fix is solving the lifecycle-to-product and transactional vector with a message orchestration layer: one system that routes, suppresses, prioritizes, and observes messages across channels. Think air traffic control for user communications.

What are transactional notifications? Transactional email examples, transactional push, and more.

Transactional notifications are automated messages triggered by user actions or system events, like password resets, order confirmations, and payment alerts. Unlike marketing messages, they require no opt-in and have legal protections under CAN-SPAM. This guide covers what transactional notifications are, how they work across email, SMS, and push channels, real-world examples for each, and how to stay compliant. Whether you're building your first notification system or auditing an existing one, this breakdown will help you understand what belongs in each category and how to route messages correctly.

A Resilient Notification Strategy for Regulated Industries

Notification compliance isn't a legal checklist—it's an infrastructure problem. In 2026, Reg E deadlines, HIPAA content rules, and TCPA consent requirements dictate your system architecture. This guide breaks down the engineering constraints of regulated notifications for fintech, healthcare, and insurance. Learn why hard-coded deadlines fail, how "alert without disclosing" works in practice, and why the smart escalation pattern (Push → SMS → Email) is the only way to satisfy both user urgency and regulatory documentation. Build systems that absorb complexity, not application code that breaks every time a state law changes.

How to Build Notification Infrastructure: Build vs Buy

There are seven realistic ways to build notification infrastructure: a unified platform with AI tooling (Courier), open-source self-hosting (Novu), push-first engagement (OneSignal), marketing-oriented automation (Klaviyo), best-of-breed provider stitching, cloud-native services, and building from scratch. The biggest recent shift is AI agents writing notification code alongside you, and platforms with MCP servers give those agents real context.

The Unsubscribe Paradox: Why Making It Easier to Leave Keeps People Around

Hiding the unsubscribe link doesn't keep people subscribed. It makes them mark you as spam, and spam complaints hurt your sender reputation roughly 1000x more than unsubscribes. The brands with the lowest unsubscribe rates don't achieve it by making the door hard to find. They achieve it by making people not want to leave. This guide covers the math behind why easy unsubscribes protect deliverability, how preference centers reduce list churn, and what your unsubscribe flow should actually look like.

Personalization Beyond "Hello {{firstName || "there"}}!"

Using someone's name matters, just not for the reason most teams think. It builds familiarity over time but doesn't change what people do. The teams getting real results have moved past names to sending based on what users do and when it matters to them. This guide breaks down five tiers of personalization, shows where the gains actually come from, and helps you figure out where to focus. No machine learning needed for the tiers that matter most.

Introducing Courier Skills: Teaching Your AI IDE to Build Notifications Correctly

AI IDEs are great at generating plausible code, but they lack durable domain context. Courier Skills gives your AI a shared baseline for building production-ready notifications, with opinionated guidance on channels, patterns, and constraints that matter in real systems.
