You’re no stranger to the immediate feelings of regret after sending a Slack message you shouldn’t have. Luckily, by default, all members can edit and delete Slack messages or thread replies.

If you ask us, changing your mind is not a mark of weakness or anything like that. It just happens to send a message and realize that you’ve done it by mistake.

Who can delete messages?

One of the best selling points of Slack remains its versatility. It enables users to delete a message they might have unintentionally sent.

Users can delete their messages one by one, in a manual process.

Workspace owners can also decide who can delete messages. It’s either everyone or only workspace owners and admins.

Assuming no changes have been made by them, follow the steps described here to make the sender’s remorse go away in an instant.

How can I delete Slack messages?

1. Delete a single Slack message

  1. Open Slack in the desktop app.
  2. Click the Sign in button on the upper-right corner of your screen, and sign in to any of your workspaces.
  3. Click a direct message on the left panel.
  4. Hover over the message you’d like to delete in the conversation.
  5. Click the More actions icon.
  6. Click Delete message.
  7. To complete the procedure, finally, select Delete.

2. Delete Slack messages in bulk without a third-party app

  1. Open Slack‘s desktop app on your computer.
  2. You may also open Slack in an Internet browser in case of not having the app.
  3. Type in the address bar, and hit the ↵ Enter key on your keyboard.
  4. Click the Sign in button on the upper-right corner of your screen.
  5. Now, click the cog (top right).
  6. Choose Additional options to bring up the archival menu.
  7. Select Set the channel message retention policy.
  8. Set Retain all messages for a specific number of days. For example, if you set a retention policy of one week, all messages in the channel or direct messages will be deleted after seven days.
  9. Click Save.
  10. Then, click Apply Settings.

If you are looking to delete multiple or all messages in a Slack conversation, we have a workaround for you. Although bulk deletion is not possible, you may configure the app to automatically delete all messages in a channel after a set period of days.

You’ll never see those 10k limit reached notifications again and that might just be music to your years.
