## Challenge Email creation has long been a solitary process, with team members working in isolation and struggling to collaborate. Resend recognized that email marketing is fundamentally a team effort, but **existing tools failed to provide a truly collaborative experience**. To break down these barriers, the Resend team developed a multiplayer editor that would: - Enable real-time collaboration - Provide instant visual feedback - Eliminate version conflicts - Improve team productivity and creativity ## Solution Resend partnered with Liveblocks to create a revolutionary multiplayer email editor that transforms how teams create and refine email broadcasts. The team implemented these key collaborative features powered by Liveblocks: ### Presence indicators Team members can see who is currently viewing and editing an email in real time, providing instant visibility into team activities and eliminating collaboration guesswork.

### Live cursors Real-time cursor tracking shows exactly where colleagues are working in the editor, creating an intuitive, connected experience that helps teams coordinate edits and provide instant feedback.

### Collaborative styling Every design change is instantly visible to all team members—from font sizes and background colors to custom CSS updates.

### Real-time field updates Beyond content and design, all editor fields update simultaneously.
