How To Clear Unread Threads In Slack

Hello there! Being a frequent user of Slack, I am familiar with the overwhelming feeling of seeing numerous unread threads in your workspace. I assure you, I have experienced the same frustration. But fret not, I am here to help. In this article, I will walk you through the steps of clearing unread threads in Slack. Let’s get started!

What are Threads in Slack?

Before we start, let’s quickly define what threads are in Slack. Threads are a way to keep conversations organized within a specific message. When someone replies to a message in a channel, Slack creates a thread, which allows for focused discussions without cluttering the main conversation. Threads help keep information in context and make it easier to follow along.

Step 1: Accessing Your Unread Threads

To clear your unread threads, you need to find them first. In the Slack desktop or web app, look for the “Threads” option on the left-hand sidebar. It usually appears below the channel and direct message sections. Click on the “Threads” option to access all your unread threads.

Step 2: Reviewing and Responding

Once you’re in the “Threads” section, you’ll see a list of unread threads. Take the time to review each thread and decide if there is anything you need to respond to or follow up on. Click on a thread to open it and read the messages within.

Feel free to add your personal touch and commentary when responding to threads. You can provide additional context, share your thoughts, or ask clarifying questions. Remember, threads are a collaborative space, so don’t hesitate to engage with your teammates.

Step 3: Marking Threads as Read

After reviewing and responding to a thread, it’s time to mark it as read. In the upper-right corner of the thread, you’ll find a small circle icon with a checkmark inside. Click on that icon to mark the thread as read.

By marking a thread as read, you let Slack know that you’ve seen and addressed the conversation. This helps you keep track of what you’ve already taken care of and what still needs your attention.

Step 4: Clearing All Unread Threads

If you have multiple unread threads and want to clear them all at once, Slack provides a convenient option for that. At the top of the “Threads” section, you’ll see a button that says “Mark all as read.” Click on that button, and voila! All your unread threads will be marked as read.


Clearing unread threads in Slack is a straightforward process that involves accessing the “Threads” section, reviewing and responding to each thread, marking them as read individually, or clearing them all at once. By staying on top of your unread threads, you can ensure better organization and more efficient collaboration within your Slack workspace.

So, next time you’re feeling overwhelmed by a pile of unread threads, follow these steps, and you’ll be able to clear them out in no time. Happy Slack-ing!
