How the agent did it
- He connected Grok Bot to his email accounts and Slack servers.
- It cleaned up 150,000 junk emails.
- It unsubscribed him from emails he never read.
@yukaichou, the gamification author, wrote that he had started trying Grok Bot and found it "awesome".
He reports two jobs. First, it cleaned up all of his 150,000 junk emails and unsubscribed him from the emails he never read. Second, it now tells him about any message across his five email addresses and six Slack servers that needs his attention, which he says keeps him organised.
Those two jobs go together. Clearing out the backlog and the newsletters he ignores leaves less noise, and the ongoing watch across several inboxes and Slack workspaces means he does not have to check each one.
The post is short. He does not say how long the clean-up took, how the bot decided what counted as junk, whether he reviewed anything before deletion, or how it alerts him. The rest of the post is about other Grok products and is not part of this use case.
The scale is the notable part: 150,000 emails is a backlog few people would tackle by hand.
Who it's for: People with years of email backlog and several inboxes and Slack workspaces to watch.
