Somebody asked

“Emails from my boss get buried, so I want them moved into their own folder.”

Our answer

You don't need AI for this

You don't need AI for this. 2 steps, nothing to interpret — a plain rule does the same job for nothing.

Only 2 actions, a single helper, almost no back-and-forth. A filter in the system you already use will do this.

What went into that
Nothing to interpret
6 of 6 signals

Only 2 actions, a single helper — this looks like a rule, not a judgement call.

Time it takes now
1 min each

Quick enough that there isn't much to win per run.

you told us it's 1 minutes each

Pays for itself in
64 months

$95 of time a month against $1.19 to run it.

we treat inside 12 months as worth doing and past 18 as not — those cut-offs are our judgement, not arithmetic

How often
90 a month

Often enough that saved minutes add up.

you said "about once a day", 4 each time — that's about 88 a month

What would change this
  • At 90 a month this doesn't pay for itself — it would take 64 months. You'd need about 470 a month before it's worth building.
  • That $6,000 is what it costs to get this running reliably — setup, a test set, and the first month of fixing it. Set it up yourself over a weekend instead and it's nearer $650 — payback drops to about 6.9 months.

$6,000 ÷ (12 months × $1.07 saved per run) = 470 a month

Take it to a builder

We don't build it. Your builder does that better than we ever could — it knows every one of its own connectors. Copy this and paste it in.

Where this goes

Open n8n, start a new workflow, and click the ✨ AI button. Paste this in.

n8n-prompt.md

Paste into n8n's AI workflow builder. Names the real nodes and says what n8n won't enforce.

Build me this workflow. I've had it designed already — the detail below is deliberate, so please follow it rather than simplifying it.

## What it should do

Move any email from one particular person into its own folder.

**Finished looks like:** Nothing from that person sits in the main inbox.

## When it should run

Daily

Use a Schedule Trigger node (n8n-nodes-base.scheduleTrigger).

## The steps, in order

1. **read inbox** — Look at new mail.
2. **move to folder** — Put the message in a folder.

## Accounts to connect

- Email (Gmail or Outlook)

Use my own credentials for each. Don't hardcode anything.

## Must-haves — please don't skip these

- One step changes something outside the system: move to folder. Point it at a test account first.
- Don't retry automatically. Nothing here says which errors are safe to retry, and retrying a write without a dedupe key applies it twice.
- Give up after 2 steps across the whole run rather than looping.

## What n8n won't enforce on its own

A workflow engine. Strong on steps and approvals, blind to agent loops. So after you've built it, these are on me — please leave a note in the workflow for each:

- **Iteration ceiling** — the design asks for stop after 2 iterations. Add an execution counter and hard-fail past the limit, or the agent can loop until the bill stops it.
- **Typed tool schemas** — the design asks for 2 tools with typed input schemas. Validate the payload yourself before the call, or the model will invent fields.

Designed with RIG. RIG works out whether a job is worth automating and writes the brief — it doesn't build or run anything.
Being straight with you

Their builder will get most of this right and some of it wrong — it always does. The part worth checking is the approvals: builders like adding a notification where the design asked for a hard stop. Everything under "what it won't enforce" is genuinely on you.
