Slack To Do List Quick Setup

Use built in features first. Add apps when you need advanced tracking or cross tool workflows.

Step
What To Do
Example
Save to Later
Hover any message and click Save. Manage from the Later view as your personal inbox.
Save a request then add a reminder for tomorrow 10 am
/remind
Create personal, teammate, or channel reminders with natural language.
/remind me send invoice Friday 4 pm
Thread tasks
Reply in thread with next steps. React with ✅ when complete to close the loop without new messages.
"Next step assign owner by EOD" then teammates react ✅
Channel Canvas
Open Canvas in a project channel and add a simple checklist and owners. Keep the plan visible and persistent.

Slack To Do List Checklist

Save actionable messages to Later. Create personal and recurring reminders with /remind.

Use emoji to claim and complete tasks. Keep follow ups in threads.

Add a project checklist in channel Canvas. Pin a short intake workflow for requests.

Connect Asana or Trello to convert messages to tasks. Post app updates back to the source thread.

Build a Personal To Do System in Slack

Combine Later, reminders, and search so nothing slips.

📥

Later as Inbox

Save any message that requires action. Review In progress daily. Mark complete to clear the queue.

Structured Reminders

Create recurring nudges. Example: /remind me review priorities every weekday 9 15 am.

🔎

Search For Tasks

Use has:📝 or your team’s task emoji to find items. Combine with in:#proj-* to filter by project.

📊
Tip: Keep a personal Canvas in your App Home or a DM with yourself for weekly goals. Link threads for context.

Turn Channels Into Lightweight Task Boards

You can run simple task flows without leaving Slack.

Pattern
How It Works
Example
Emoji claim
First responder reacts with 👀 or ✋ to claim a task. Prevents double work.
Customer request posted → ✋ means I got it
Status by emoji
Use 🕐 for in progress and ✅ for done. Keep chatter in the thread.
Original message shows latest status at a glance
Recurring prompts
Automate check ins with channel reminders.
/remind #proj-site Updates due every Friday 3 pm

Common Slack To Do List Mistakes

Leaving messages unread as reminders instead of using Later. Starting tasks in DMs where nobody has visibility. Mixing status chatter into the main channel instead of threads. Forgetting owners and due dates. Installing apps without posting updates back to the original message.

Overcomplicating with too many tools before mastering the built in options.
