How to mark messages in RoundCube

Mark messages as read, unread, or flagged in RoundCube webmail to keep track of what needs your attention.

1 min read Updated 11 Jun 2026

Marking messages helps you keep track of what still needs your attention. RoundCube lets you mark messages as read, unread, or flagged.

Mark a message

  1. Select a message (or several) in your list, or open a message.

  2. Click Mark in the toolbar and choose an option:

    The Mark menu in RoundCube

    • As read / As unread - a bold subject and a dot indicate an unread message; marking it read clears that.
    • As flagged / As unflagged - adds a flag so you can spot important messages and find them again easily.

You can also mark a message read or unread quickly by clicking the unread dot next to it in the message list.
