Custom Split Inboxes

Splits are intentional sections at the top of your inbox designed to enhance focus. They help you prioritize important emails, batch process similar messages, and manage your inbox more efficiently.

The total conversation count appears next to each Split. If you've reached Inbox Zero in a Split or the count exceeds 999, the number will not be displayed.

💡 Tips

  • Splits are designed to enhance focus, so use them thoughtfully for your key workflows and priorities. Having two to five Splits helps structure your inbox and prioritize emails effectively, while exceeding five may slow productivity by increasing email processing time.
