Your inbox is half newsletters, a quarter receipts, and somewhere in there is the one email that actually matters. Let's have an AI sort it for you: label everything, flag the important stuff, never auto-delete.
The short pick
n8n — a visual workflow builder with a Gmail Trigger and AI nodes. n8n's own template library has several "classify and label Gmail with AI" workflows ✅, so you're not inventing anything new.
Price: the self-hosted Community Edition is free ✅ (you run it yourself, e.g. with Docker). n8n Cloud starts around €24/mo with a 14-day trial ⚠️ unverified exact price. You'll also pay a few cents to a few dollars a month for the AI model's API, depending on volume.
Alternatives
| Tool | Good for | Price (checked Oct 16, 2026) |
|---|---|---|
| Zapier (with AI steps) | Fastest setup, no server | Free 100 tasks/mo; Professional from $19.99/mo annual ⚠️ unverified |
| Gmail filters (no AI) | Rules like "from: @store.com → Receipts" | Free |
| Claude Code / Codex writing a small script | You want full control and own the code | Claude Pro $20/mo ✅ / ChatGPT Plus $20/mo ✅ |
Honest take: do Gmail filters first for the obvious senders. Use AI only for the fuzzy stuff that rules can't catch.
How to start
- In Gmail, create your labels first:
AI/Action,AI/Read-later,AI/Receipts,AI/Newsletters,AI/Other. - In n8n: Gmail Trigger (poll unread inbox messages) → AI Agent or Text Classifier → Structured Output Parser (returns JSON like
{"label":"AI/Receipts"}) → Switch → Gmail: add label. - Run it on 20 emails in test mode. Read every decision. Tweak the prompt.
- Only add labels. Don't archive or delete until it's been right for a week.
