Reply to Mattermost messages

Tap on a message to reply to it, or long press and select Reply.

Depending on how your system admin has configured Mattermost, you may be able to edit, restore, and delete messages after you’ve sent them.


It’s easy to return to a message in progress with global message drafts. Find all of your draft messages in the Drafts view available at the top of the channel sidebar. See the draft messages documentation for details.

Organize conversations into threads#

When you reply to messages, those replies are organized into a conversation thread. Threaded conversations are easy to follow and allow multiple parallel conversations to occur at the same time without confusion.

Using Mattermost in a web browser or the desktop app, replies appear indented slightly in the center pane to indicate that they are child messages of a parent message, and selecting the reply link opens a sidebar in the right-hand sidebar in a web browser and the desktop app. To expand the right-hand sidebar to its full width, select the Expand icon with two arrows at the top of the sidebar.

Expand right-hand sidebar to its full width

To shrink the right-hand sidebar to its original width, select the same Collapse icon.

Work with Collapsed Reply Threads#

Collapsed Reply Threads offer a new way to organize conversations within channels. See our Organizing Conversations using Collapsed Reply Threads documentation to learn more.
