How To Add Person To Existing Slack Conversation

One helpful feature of Slack is the ability to add someone to a conversation that is already in progress. This can be helpful if you want to involve someone who was not originally included in the discussion. Whether it’s a new member of your team or a coworker from a different department, Slack offers a straightforward way to include them in the conversation without creating a new thread. In this article, I will provide a step-by-step guide for adding a person to an existing Slack conversation.

Step 1: Open the Slack conversation

To add a person to an existing Slack conversation, first, you need to open the conversation you want to add them to. You can do this by clicking on the channel or direct message on the left sidebar of your Slack interface.

Step 2: Click on the “Add People” button

Once you have the conversation open, you will see an options menu at the top right corner of the conversation window. Click on the “Add People” button in that menu.

Step 3: Enter the person’s name or email

A pop-up window will appear, allowing you to search for the person you want to add. You can enter their name or email address in the search bar. Slack will start suggesting names as you type, making it easier to find the right person.

Step 4: Select the person to add

Once you have entered the person’s name or email, Slack will display a list of matching results. Select the correct person from the list by clicking on their name.

Step 5: Click on the “Add” button

After selecting the person you want to add, click on the “Add” button in the pop-up window. Slack will then add the person to the existing conversation, and they will be able to see all previous messages and join the ongoing discussion.

It’s worth noting that the person you add will receive a notification about being added to the conversation. This ensures that they are aware of the ongoing discussion and can actively participate in it.

Personal Commentary:

As a long-time Slack user, I find the ability to add people to existing conversations extremely helpful. It saves me time and effort by avoiding the need to start a new conversation or reiterate previous discussions. Additionally, it fosters collaboration and inclusiveness within the team, as everyone can stay up to date and contribute to the conversation seamlessly.


Adding a person to an existing Slack conversation is a straightforward process that can greatly enhance communication and collaboration within your team. By following the steps outlined in this article, you can easily include someone in a discussion without missing a beat. So, next time you need to involve someone who wasn’t initially part of the conversation, just give Slack’s “Add People” feature a try!
