What they did
The user gave an AI agent access to email subject lines from 1,847 unread messages. The agent grouped the messages into six folders, wrote one-line reply drafts for some of them, and marked urgent items for review. The user handled the urgent emails personally and sent the drafted replies.
How it went
In 40 minutes, the inbox was organized into 6 folders with 12 draft replies ready. The agent also identified 3 urgent emails; nothing was sent automatically.
Tips
Limiting the agent to subject lines can make triage faster and safer. Ask it to pause before any sending, deleting, or submitting so you can review first.

Try it yourself with Claude Cowork

Review my unread email in [Gmail/Outlook] using only the subject line and sender at first. Group everything into these folders: [folder names]. For messages that belong in [reply folder], write a single-sentence draft reply and save it as a draft, but do not send anything. Flag any emails that seem urgent or need my direct attention, and stop so I can approve all sends, deletions, or other irreversible actions before you do them.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
