Custom Split Inbox

Split Inboxes are intentional sections at the top of your inbox designed to enhance focus. They help you prioritize important emails and batch process similar messages.

To help you reach Inbox Zero, the total number of conversations appear beside each Split. If you've reached Inbox Zero in a Split or if the total exceeds 999, the count will not be displayed.

To navigate between Splits on Desktop, hit Tab to move right and Shift+Tab to move left. On Mobile, simply tap the Split name.
