In any channel in Slack, you can type "/todo list" to see the most recent list of tasks. From here you can update tasks, complete them and create new ones.
Once you have your to-do list in Slack up and running, there a few notification settings that are worth mentioning. Type "/todo list" and click on the Settings button to customize these settings.
Tasks created: by default, when you create a task in Slack using /todo, the confirmation message is only visible to you and not the channel. You can change this by enabling notifications for all tasks created.
Tasks completed: by default, when a task is completed, a notification is shared in the channel. You can turn this off, by unchecking the checkbox in the settings.

You can see the unique email address by typing "/todo list" and click on [Settings]. To learn in more details how this feature work, you can visit our article Using email to create a task
