How to Bulk Delete Slack Messages from Channels

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.
