Courier Console v3: redesigned from the ground up

A faster, cleaner, more consistent Courier. Rolling out now.

We're rolling out a complete redesign of the Courier console. It touches everything: the visual language, the underlying architecture, and the overall experience of working in the app.

Why we're doing this

When you're in the Courier console, the experience should feel sharp, clear, and fast. We rebuilt it from the ground up with three goals:

• Clarity. Every page should be easy to read, easy to navigate, and easy to understand at a glance.
• Speed. The architecture should be fast for you and fast for our team to build on.
• Consistency. The same patterns, the same behaviors, the same quality everywhere.

The result is a new visual language, a modern architecture, full light and dark mode support, and an experience that matches the quality of the rest of Courier.

How we're rolling it out

We're shipping UI v3 in phases over the next 4-6 weeks. The app shell and navigation come first, followed by the builders, then the remaining pages and forms.

No breaking changes. Your workflows, templates, integrations, and configurations all stay exactly where they are. Same features, same URLs. You don't need to do anything.

What this means going forward

The new architecture means we ship console improvements faster. The codebase is clean, conventional, and easy for our team and AI agents to iterate on. The console will keep pace with the rest of the product from here.

UI v3 starts rolling out this week. If you have feedback as it lands, we want to hear it.
