Sunsetting the legacy in-app editor

Released

Chances are that if you’ve built in-app messages in Customer.io, you’ve already used our new, visual in-app editor! To continue delivering a more user-friendly, flexible in-app messaging experience, we’re ending support for our legacy in-app editor January 1, 2026. If you haven’t made the switch yet, now’s the perfect time to start using the new in-app editor, designed to help you build better in-app experiences.

We’re phasing out the legacy editor in two stages:

  • On October 1, 2025, the legacy editor becomes edit-only. You can continue editing messages in the legacy editor, but you won’t be able to create new ones.

  • On January 31, 2026, the legacy editor becomes read-only. You’ll still be able to see messages in the legacy editor, and they’ll continue working—but you won’t be able to edit them.

We won’t delete your existing in-app messages! Any legacy in-app messages in active campaigns will continue working as expected.

What you need to do

To ensure a smooth transition:

  1. Use the drag-and-drop visual editor when creating new in-apps
  2. Rebuild legacy messages in the new editor that you might need to edit after January 2026
  3. Check out the prebuilt templates in the new editor to get started faster

 The new editor is already available in your workspace

Just select “drag-and-drop editor” instead of “Legacy editor” when creating your in-app message.

Why switch?

The visual editor offers everything you love about the legacy editor—and much more:

  • Drag-and-drop design tools with rich components
  • Video and custom styling support
  • Ability to easily move between visual and HTML editing
  • Ready-to-use templates for surveys, banners, NPS ratings, and more
  • Improved design consistency and flexibility

Explore all templates in the editor by selecting Templates from the toolbar.
