How to Design an In-App Notification Center: UX tips and examples

A design-focused guide to building an in-app notification center people actually use. Covers the UX decisions that matter (entry point, information hierarchy, read state, grouping, empty states, inline actions, real-time, accessibility), then shows three ways to execute in Courier Inbox: brand-match with a theme, take over individual pieces with render props, or go fully headless with the `useCourier` hook. Ends with a pre-ship checklist.

How Apple's on-device AI works, and what it changes for your users

Apple's 2026 on-device models (AFM 3) are good enough to read, rank, and summarize everything that lands on your phone, locally and for free. Here's how they actually work, in plain terms, and how a model that reads every message before your users do changes what you should send.

Apple Intelligence finally got smart. Here's how it changes the notifications your users see.

Apple Intelligence's on-device models got dramatically better in iOS 27, and they now summarize, rank, and filter notifications before your users ever see them. There's no API to control that, so the words you send are the only lever you have. Here's how notification summaries work and how to write for them.

Broadcasts: send one-time messages to your users, right from Courier

Email open tracking and consent: the new rules in Europe

Regulators in Europe are treating the email open-tracking pixel like a cookie, which means it needs consent before it fires. Here's what changed, who's actually in scope, what compliance requires, and how to keep sending while gating tracking on consent, including how to wire it up in Courier.

The Future-Proof Multichannel Notification System: Built for Humans and AI Agents

Multichannel delivery is now table stakes. In an AI world, future-proof means a notification system both your team and AI agents can build and run.

You can build anything now. That's exactly why you shouldn't build this.

AI made building software cheap, so the temptation is to build everything. But owning infrastructure is a permanent draw on your scarcest resource, attention. The value lives at two ends, the systems everything runs on and the product only you can make; the move is to build less, buy the opinionated platform, and let an agent operate it.
