How Resend transformed email collaboration with real-time multiplayer editing
Discover how Resend transformed email creation from a solo task into a dynamic, collaborative experience with Liveblocks—enabling teams to draft, design, and refine emails together.
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.
Email is not a single-player game. We wanted to create an editor that feels like a live, collaborative workspace where teams can work together seamlessly.Zeno RochaFounder and CEO at Resend
