Categories

One category, like Receipts, can hold mail from every inbox. Rules sort each email into one category as it arrives. The colored bar on the left of an email row is its category.

Create and edit categories

Settings → Categories.

Drag categories in the sidebar to change their order.

Change one email's category

To change where that kind of mail goes from now on, edit the rule.

Hide a category

Edit the category and turn on Hidden. Rules keep sorting mail into it. Open a hidden category from Settings → Categories, or from the category chip on one of its emails.

Delete a category

Change any rule that sorts mail into the category before deleting it. To move the mail already in the category, select it in the category's view and choose Reprocess.

To bring back a deleted category, create one with the same name.
