- Faster performance: Emails open instantly, scrolling is fluid, and routine actions like archiving or replying are now faster too!
- Modern design: A refreshed interface with simpler navigation makes it easier to manage your inbox.
- Offline mode: Read, write, and organize emails even without internet. Everything syncs when you’re back online.
