Message threading in Thunderbird - keep messages grouped by conversation

Threading is a useful way of displaying your message list in Thunderbird. Instead of just listing messages sorted by date, Thunderbird can group messages in tree-like structures by conversations. This is the default view starting from version 102.

What is threading?

Threading puts email conversations together hierarchically. This is especially handy to keep conversations on mailing lists organized, with a lot of people replying to various messages of a conversation. Also, it saves you from losing individual messages of a conversation in stacks of other messages, and lets you perform mass actions like deleting or ignoring a whole conversation.

Enable threading on a folder

Threading is turned on by default in Thunderbird for all folders. Otherwise you can easily turn it on for the current folder.

  1. Click the appmenu button and select the View menu (or, press the Alt key to make the classic menu bar appear and open the View menu).On the menu bar, click on the View menu.At the top of the Thunderbird window, click on the View menu.
  2. In the Sort by submenu, choose Threaded.

Your messages will be bundled into tree structures that can be expanded or collapsed with the > or v arrow next to the subject.

Disable threading on a folder

If threaded view doesn't suit you, you can disable it by following the above steps and selecting Unthreaded in the Sort by menu.

Applying threading to other folders

Starting with version 102.2.1, you can apply the current thread view (enabled or disabled) to other folders through the message list's column chooser. Using this method, all of the current folder's view settings will be applied, not just the threading setting:

  1. Click the column chooser icon to the far right of the message list column headers ("Select columns to display").

  2. Click Apply Current View to... near the bottom of the menu.
  3. Choose a target folder from the Folder... menu to apply the current view only to a single folder, or from the Folder and its children... menu to apply it to multiple folders, which can also be an entire email account.

Managing threads

  • To perform an action for all messages in a thread - for example delete, archive or tag them - select a collapsed thread and click the respective button. You can still perform actions for individual messages by expanding the thread and selecting the message.
  • If a conversation on a mailing list doesn't interest you, you can ignore it. Ignoring will hide (but not delete) a thread from your list of messages, and disable new mail notifications for new replies. To ignore a thread or a subthread, see Ignoring threads.

Other ways of threading conversations

Would you like to put conversations together in a different manner? Perhaps like Gmail does, linearly and with your messages included? Try the Thunderbird Conversations add-on or search the Thunderbird Add-ons site to find an add-on that suits you.
