Why it matters
Email is where a lot of admin quietly piles up. An agent that can read, sort, draft and follow up turns an inbox from a to-do list into something closer to a summary. It is one of 106 sightings filed under Email & Inbox on Agent Sightings (number 47 by interest), and one of 164 involving Claude Code.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude Code or any similar agent and adjust the details to your situation.
Go through my mail for this goal: index a newsletter archive and repurpose writing. Propose labels, drafts, and unsubscribes as a checklist; change nothing until I approve.
Tip: Start with read-only access or 'draft, don't send', and check a few drafts before trusting it to send anything.
