Appearance and mail display

Choose a theme, reading pane and accent colour, and set text size, conversation view and what Delete removes.

Two pages in Settings control how the web app looks and how mail is shown: Appearance and Mail.

Appearance#

Open Settings > Appearance.

SettingChoices
ThemeLight, Dark or System, which follows your device.
Reading paneRight shows the list on the left and the message on the right. Off opens the message full width. It applies on wide screens. Phones always use full width.
Accent ColorCyan, Blue, Purple, Green, Orange or Pink.

The accent colour is saved in the browser you are using. Set it again on another browser or device.

Mail#

Conversation view#

Group messages into conversations is a switch.

  • On: one row per conversation.
  • Off: one row per message, and Sent shows only mail that is in Sent.

When I delete#

Choose what Delete removes:

  • This folder keeps your copy in Sent when you delete from the Inbox.
  • Whole conversation removes every copy of the conversation.

Summary cards and categories#

The same page holds the Summary cards switches and the Inbox categories card. See Message intents and Smart categories.
