Glancing marks messages as read without having to open them.
Sometimes the subject of an email says it all, so we designed Glancing to mark messages as read without having to open the email itself.
Glancing only happens for:
Conversations are unaffected by Glancing.
You can tell your glancing at an email when the unread badge slowly begins to fade out. Once the badge has completely faded, the message will be marked as read.
If you scroll past the message before the badge has faded, it won’t be marked as read.
You can disable Glancing in Settings and Preferences.
