Slack Deletion Features
Mass Delete Slack Messages in Channels
Slack keeps everything you've ever typed at work. Redact deletes your Slack messages in bulk, from as many channels as you were in, filtered by date, keyword, or content type, with a preview first.
Mass Delete Slack Direct Messages
Direct messages are where work talk gets honest, and personal. Redact bulk deletes your Slack DMs, whole conversations at a time, filtered by date or keyword, with a preview before anything is removed.
Delete Your Entire Slack History
People leave jobs. Their Slack messages stay behind. Redact wipes your whole Slack history in one run, channels and direct messages together, before you hand back that work laptop.
Deletion Mode
Delete Slack Messages by Date Range
Remember that week last month when you didn't get the promotion you were after, and went on Slack to tell everyone how dumb your manager was? Well, the last thing you need is for someone to leak those messages to your manager, ensuring you will never get that promotion, and maybe even lose your job all together. With the Redact date filtration tool, you can target those exact types of messages and DMs you made. Our software allows you to choose specific dates or date ranges to delete from. The date filtration tools works by start date (only delete after this date) or end date (only delete before this date). You can select by month by clicking the month label, and by year by clicking the year label. Clicking the Reset red text will reset the date value for that field.
Date Range
These dates are set to specific dates. The Scheduler feature will delete only between these dates.
Target & Delete by Keyword
The keyword filter is one of Redact's most potent tools. With the keyword tool, you can target all of your past Slack activity and easily find the naughty stuff. Redact will search through all of your old direct messages and public chat messages to find and delete your dicey messages based on a keyword search. Target anytime you mentioned a certain person's name, a specific word like "HR", or when you used one of those all so common 4 letter words. The Redact App is free to download and test, what are you waiting for? Take back control of your Slack history and gain peace of mind!
