My inbox had 847 unread emails on a Monday morning. I don’t mean 847 since Friday. I mean total — stuff from weeks ago that I’d meant to “get to.”

Here’s the prompt I now run every Monday, and what it does for me. It’s worth ten minutes of your time if you’ve ever stared at a full inbox and felt your day slide away.

The setup

I use Gmail, but this works anywhere you can export or paste emails. I grab the subject lines, senders, and first 200 characters of the body of everything unread from the last 30 days — usually via copy-paste from Gmail’s search view. You don’t need an API, a plugin, or anything fancy.

Then I drop it into Claude or ChatGPT with this prompt:

You are my morning assistant. Here is a dump of unread emails. Sort them into three buckets: Act — needs a reply, decision, or action this week. Tell me the 10-word version of what’s needed and the sender. Read later — useful but not urgent. One-line summary. Ignore — newsletters, promotions, notifications. Just count them. Do not draft replies. Do not email anyone. Just the triage.

That’s it. Copy, paste, go.

What actually happens

For me it usually lands 20–30 in Act, 50–80 in Read Later, and the rest in Ignore. The Act list always contains 2–3 items I would have missed, and they’re almost never the ones I thought were urgent.

Last week it caught:

  • A payment-method-expiring email I’d skimmed and forgotten
  • A friend asking about a wedding date I hadn’t replied to (gulp)
  • A vendor following up on a contract I thought I’d signed

None of those were flagged by Gmail’s priority inbox. All three would have cost me something if I’d missed them another week.

What doesn’t work

It’s not great at understanding nuance in relationships. If your boss writes “no rush” they mean rush. The AI takes that literally. I re-read the Act pile myself before I act — the point is that I’m re-reading 20 emails instead of 847.

It also can’t tell you which of your “read later” articles is actually worth your evening. Read Later is still a graveyard. The win is that it’s a smaller graveyard.

One thing to try this week

Next time your inbox feels heavy, don’t try to triage it in your head. Grab the last 30 days of unread mail, drop it into the prompt above, and give yourself ten minutes.

If nothing else, you’ll find one thing you would have missed. That alone covers the time.

The best AI use cases right now are the boring ones. Fancy agents are cool. Triaging your inbox on a Monday morning is what actually changes your week.
