Bulk Slack Message Removal
v2.0 Updated Aug 24, 2025 1.15MiB
⚠️Requests 2 sensitive permissions
Description
Delete Slack messages in bulk. It supports removing slack messages in public channels, private channels, group chat, and DM. (Caveat: for group chat and DM, you can ONLY remove your own messages).
● No OAuth required.
● Unaffected by recent Slack API trottling changes.
Also, it removes threaded messages as well.
Disclaimer: This is a paid product.
ATTENTION:
There are 2 different types of licenses. You must be an admin in order to delete other people's messages. Once again, you can't delete other people's DM or group chat messages.
Admin License - If you are a Slack admin, you should choose this license. It would allow you to remove other people's messages in channels. A non-admin license will let you remove your own messages only.
NOTE: you can only remove your own messages in a DM, however.
Non-admin License - You should choose this license if you are simply a member in your Slack workspace. Nothing prevents you from using an admin license, but you'll still only be allowed to remove your own messages.
Instructions
* Log in with your Slack login.
* Get a license via Gumroad and enter it in the extension popup.
* Select the target channel, DM, etc..
* Select the message sender whose messages you would like to delete.
* Click on the Bulk Delete button.

It's OK. Very slow at processing and no button to stop it once started. Selecting time zone doesn't work so you can't run it on time range.

It works well for deleting your own slacks but I was unable to get it to work to delete other's (using the admin version).
