Merging threads

When a customer contacts you about the same issue across multiple threads, merging lets your team track and respond to everything from one place.

How it works

When you merge two threads, you pick a parent thread and a child thread. The parent stays active. The child is set to Ignored status. Any new messages sent to the child thread automatically appear in the parent's timeline.

Merging Two Threads

There are three ways to start a merge:

  1. Open the thread, click the overflow menu in the thread header, and select Merge thread.

  2. Open the command palette with ⌘K and search for Merge thread.

  3. Use the thread links panel on the thread page.

Unmerging Threads

  1. Open either the parent or child thread.

  2. Click the overflow menu in the thread header.

  3. Select Unmerge thread.

What Happens After Merging

Area

Behaviour

Parent thread timeline

New messages from the child thread appear as grouped "New activity in merged thread" entries, showing the child thread's reference number and title.

Child thread status

Automatically moves to "ignored."

Child thread view

Displays a "Thread is merged" card indicating the parent thread, with a link to navigate there.

Replying

A reply composer appears inline on the parent thread for each batch of merged messages, allowing you to respond to the child thread's customer without leaving the parent.

Thread links

Both threads show the merge relationship in their thread links section, with distinct icons indicating which is the parent and which is the child.

Supported Channels

Merged thread messages work across all communication channels, including email, chat, Slack, Microsoft Teams, and Discord. When replying from the parent thread, the response is sent through the child thread's original channel.

Things to Know

  • You can only merge threads created by the same customer/tenant/company

  • A thread can only be merged as a child into one parent thread at a time.

  • You cannot merge a thread into itself.

  • Merging is available for internal threads only - it is not available for external issue tracker links (such as Linear or Jira).
