Users can search for all sender emails and emails with the same subject. You can also open multiple emails simultaneously in new windows, add a label, move emails, mute conversations, and enable snooze.
Prior to this rollout, Gmail enabled a right-click menu to archive emails, mark them as read or unread, and delete messages. These features will continue to be available in the updated menu.
The new options will be phased in for G Suite users, starting with quick release domains (where users will get new features when they're made public) Monday. Planned release domains (where users will be publicly available at least one week after publication) will receive this feature from February 22nd.
