Courier’s new notification preferences Web Component makes it easy to add a complete preferences center to any web app with a single HTML element. Users can opt in or out of specific notification topics, choose which channels deliver each topic, and set digest schedules for lower-priority updates. The component works across frameworks like React, Vue, Svelte, Angular, or plain HTML, with light and dark theming options to match your product. It also reuses existing Courier Inbox authentication, so teams can ship user-controlled notification settings without building or maintaining the preferences UI from scratch.
