How to Create a To-Do List for Your Slack Messages

Stop losing tasks in the noise. Here's how to turn Slack messages into an organised, prioritised to-do list - so nothing slips through the cracks.

Slack is brilliant for collaboration. But ask anyone who uses it seriously and they'll tell you the same thing: tasks get buried, context gets lost, and important messages disappear into a river of notifications. Sound familiar? You're not alone - and the good news is there's a straightforward fix.

The Problem: Slack Wasn't Built as a Task Manager

Slack was designed to make communication faster - and it does. But when action items and assignments are buried inside threads, channels, and DMs, tasks get missed. According to Slack's own research, employees spend only 32% of their time on meaningful work, with the rest lost to coordination and context-switching. Each notification pulls you away from focus, and it takes roughly 23 minutes to get back into flow.

"Slack isn't the problem. The way we manage it is."

Why a Dedicated To-Do List for Slack Changes Everything

The solution isn't to use Slack less - it's to use it better. Specifically: to capture tasks at the moment they arrive and move them out of the message stream into a structured, prioritised to-do list that you can work from deliberately.

Here's what a Slack-connected to-do list gives you:

• Never miss a task again. Action items are captured at the source - no more relying on memory or scrolling back through channels to find that request from Tuesday.
• Work on what matters. A prioritised list lets you decide each morning what to focus on, rather than reacting to whatever happens to ping you next.
• Stop the scroll. When tasks live in a proper system, you don't need to re-read threads looking for buried follow-ups.
• Reduce cognitive overload. Getting tasks out of your head and into a trusted system frees up mental bandwidth for the actual work.
• Keep context intact. A good integration preserves the original Slack message, so you always know where a task came from.

How to Build Your Slack To-Do List: A Step-by-Step Approach

Step 1 - Tame Your Slack Setup First

Before connecting a task management system, it helps to get your Slack house in order. A few simple changes make a big difference:

Tame your notifications. Mute noisy channels and enable alerts only for direct mentions or keywords. Use Do Not Disturb during focused work blocks. Context-switching costs you significant productive time every day - protecting your attention is non-negotiable.

Organise channels by priority. Create sections like "Urgent", "Projects", and "Social". Archive or leave channels that aren't relevant to your current work. Pin key documents or decisions to avoid repeated searching.

Establish a clear saving habit. Every time a message contains a task, action item, or something you need to follow up on - save it. Slack's "Save for Later" (the bookmark icon) is your trigger. This is the behaviour that everything else builds on.

Getting control of your Slack setup is the foundation everything else rests on. Studies show that 38% of employees feel overwhelmed by the volume of messages they receive, leading to missed details, poorer decisions, and eventually burnout.

Step 2 - Connect Slack to a Task Management App

The real unlock is connecting Slack to a dedicated task management tool so that saved messages automatically become actionable to-do items - no manual copy-pasting, no sticky notes, no relying on memory.

Think of it this way: Slack is where tasks are born. Your task manager is where they go to live. Connecting the two means nothing falls through the gap.

When you connect a tool like Briefmatic to your Slack account, saved messages are automatically converted into tasks, ready to be prioritised, scheduled, and tracked to completion. Briefmatic gives you both a Kanban board view and a list view - so you can work in whatever format suits you best. Prefer to see everything laid out visually and drag tasks between columns? Use the board. Want a clean, linear to-do list to work through? Switch to list view. Either way, updating your tasks takes seconds, not minutes - which means you'll actually keep things up to date.

Step 3 - Choose the Right Tool for Your Workflow

There are a few strong options for turning Slack messages into tasks. Here's how the main ones compare:

Briefmatic is best for remote and hybrid professionals who want automatic, context-aware task capture from Slack - and other tools like Gmail, Figma, and Google Calendar. When you save a message in Slack, Briefmatic auto-detects it and creates a task directly on your Kanban board, task list, or calendar. No manual copy-paste required. It's designed specifically to reduce mental overhead and keep everything in your actual workflow.

Todoist is a good option for individuals with a light to medium task load. You can turn Slack messages into tasks via the "More actions" menu and assign due dates and labels from within Slack. It's less suited to cross-functional team collaboration.

Trello works well for teams already managing projects inside Trello. You can use /trello commands to create cards from Slack conversations, but the process is more manual and requires more deliberate intent to use consistently.

If you want low-friction, automatic Slack-to-task conversion - especially if you frequently get action items in Slack, work asynchronously, or juggle tasks across multiple tools - Briefmatic is likely the best fit.

How to Use Your Slack To-Do List Effectively

Having the system is only half the battle. Here's how to make it a habit that actually sticks.

Do a daily 5-minute board review. Each morning, open your Briefmatic board and decide the two or three things that most need your attention that day. This is your north star for the day - not whatever notification arrives first.

Save as you go, not later. The moment you read a message that contains a task, save it immediately. Don't think "I'll come back to that" - you won't. The save habit is everything.

Use your board to prioritise, not just collect. A to-do list that's just a pile of tasks isn't much better than a pile of unread messages. Move tasks into priority order, give them due dates, and regularly archive completed items to keep the board clean.

Clear your saved items regularly. Your Slack "Saved Items" list is not a permanent home for tasks - it's a staging area. Make sure every saved message gets processed onto your board, or deleted if it turns out it wasn't actually a task.

The Bigger Picture: Getting Slack to Work For You

There's a version of Slack that's a productivity killer - a place where attention fragments, tasks disappear, and context-switching drains your cognitive reserves before noon. And there's a version of Slack that's genuinely powerful: a communication hub where important information flows cleanly to the right people, and tasks get captured and acted on reliably.

The difference between these two versions isn't Slack itself. It's the systems and habits layered on top of it. A to-do list connected to your Slack messages is one of the highest-leverage habits you can build - because it transforms the most common source of dropped tasks (message chaos) into a structured, prioritised workflow.

Slack isn't going anywhere, and neither are the tasks that arrive inside it. The question is whether those tasks end up in a trusted system where you can act on them deliberately - or scattered across channels, threads, and memory, waiting to be forgotten.

With a tool like Briefmatic, the setup takes minutes. The impact - fewer missed tasks, less scrolling, less cognitive overload, more time on meaningful work - lasts every single working day.
