mailtrim 0.4.2

Privacy-first email inbox management — Gmail + IMAP, local-first core, optional AI via Anthropic API

mailtrim

Clean your inbox safely in seconds. Everything goes to Trash. Undo anytime.

---

Quick Demo

pip install mailtrim
mailtrim setup          # connect Gmail or IMAP — guided, ~2 minutes
mailtrim stats          # rank your inbox clutter by impact
mailtrim purge          # bulk-delete what you picked — goes to Trash

That's the whole workflow. No API key. No subscription. Nothing sent to any server.

---

Why mailtrim?

• Finds what's actually filling your inbox — ranks senders by storage impact, not just count
• Bulk cleanup in seconds — delete 300+ emails from one sender in a single command
• Nothing is permanently deleted — everything goes to Trash, recoverable for 30 days
• Privacy-first — core commands run entirely on your machine; AI is opt-in and off by default
• Works with Gmail and IMAP — Outlook, Fastmail, iCloud, any IMAP server

Safety Guarantees

Guarantee	How it works
Trash first	Every delete sends mail to Trash, not permanent deletion
Full undo	mailtrim undo reverses any operation within 30 days
No cloud required	stats, purge, undo, setup are 100% local
AI is optional	AI is off by default — you enable it explicitly
Dry-run available	purge --json shows what would be deleted before you confirm

---

60-Second Quickstart

First time:

pip install mailtrim
mailtrim setup    # walks you through Gmail auth and runs your first scan

After setup:

mailtrim stats                          # see your inbox ranked by clutter
mailtrim purge                          # interactive: pick senders, confirm, done
mailtrim purge --domain linkedin.com    # target one sender directly
mailtrim undo                           # reverse anything you just did

Already set up? Jump straight to cleanup:

mailtrim quickstart    # one command — scans, ranks, shows the safest first action

Privacy

Data never leaves your machine unless you explicitly enable cloud AI.

• All data stored in ~/.mailtrim/ — no telemetry, no analytics, no external sync
• OAuth token written chmod 0600 — owner read-only
• stats, purge, undo, setup are fully local — no API key, no network calls
• AI mode is shown in every command output:
  • AI: OFF no data leaves your machine (default)
  • AI: LOCAL runs on your machine — nothing sent externally
  • AI: CLOUD email data may be sent to Anthropic
• When cloud AI is enabled, a warning appears before any data is sent
• Cloud AI features send only email subjects and 300-character snippets — never full body content

Revoke access at any time:

• Google: myaccount.google.com/permissions → remove mailtrim
• Local: rm ~/.mailtrim/token.json

See PRIVACY.md for the full data flow.

mailtrim stats	Rank all senders by storage impact with confidence scores
mailtrim stats --since 30d	Scope the scan to the last N days
mailtrim stats --share	Generate a shareable summary (Twitter/plain)

mailtrim unsubscribe [e-mail]	Unsubscribe via List-Unsubscribe header

Optional AI (requires mailtrim config ai-mode cloud)

mailtrim bulk "archive newsletters older than 60 days"	Natural language bulk operation
mailtrim avoid	Surface emails you've viewed repeatedly but never acted on
mailtrim digest	Weekly inbox summary — patterns, action items, one cleanup suggestion

AI enrichment (local — no Anthropic key)

mailtrim stats --ai-backend ollama --ai-model phi3   # requires Ollama
mailtrim purge --ai-backend llama                     # requires llama.cpp at localhost:8080

---

Setup

Gmail (OAuth)

# 1. Get credentials.json from Google Cloud Console (one-time, ~10 minutes)
#    console.cloud.google.com → New project → Gmail API → OAuth 2.0 Client ID (Desktop)
#    Download JSON → save to ~/.mailtrim/credentials.json

# 2. Authenticate
mailtrim auth    # opens browser once, stores token locally

# 3. Run
mailtrim stats

"This app isn't verified" — expected. You're authorising your own app to access your own inbox. Click Advanced → Go to mailtrim (unsafe) to proceed.

IMAP (Outlook, Fastmail, iCloud, self-hosted)

mailtrim setup    # choose IMAP at the prompt — enter server, user, password

Setup saves your server, username, port, and folder to ~/.mailtrim/.env. After that, every command works with no flags:

mailtrim stats       # reads persisted IMAP config automatically
mailtrim purge       # same
mailtrim undo        # same

For the password, set it once in your shell environment (never stored on disk):

export MAILTRIM_IMAP_PASSWORD="your-app-password"

Or mailtrim will prompt securely each time.

Confidence Scores

purge shows a 0–100 score that estimates how safe bulk-deletion is:

Signal	Weight
List-Unsubscribe header present	30 pts — sender self-identifies as bulk/marketing
Age ≥ 180 days in inbox	up to 35 pts — emails sitting >6 months are rarely actionable
Volume ≥ 50 from one sender	up to 35 pts — high frequency = almost certainly automated

🟢 ≥70 Safe to clean · 🟡 40–69 Needs review · 🔴 Sensitive (bank, health, legal — never auto-suggested)

Scores are heuristics. The 30-day undo exists precisely because no heuristic is perfect.

---

Configuration

Settings via ~/.mailtrim/.env or environment variables:

Variable	Default	Description
MAILTRIM_AI_MODE	off	AI mode: off · local · cloud
ANTHROPIC_API_KEY	(not set)	Required for cloud AI features
MAILTRIM_AI_MODEL	claude-sonnet-4-6	Claude model for cloud AI
MAILTRIM_DRY_RUN	false	Preview without executing
MAILTRIM_UNDO_WINDOW_DAYS	30	How long undo logs are kept
MAILTRIM_DIR	~/.mailtrim	Data directory
MAILTRIM_PROVIDER	gmail	Active provider — set automatically by mailtrim setup
MAILTRIM_IMAP_SERVER	(not set)	IMAP server hostname — set automatically by mailtrim setup
MAILTRIM_IMAP_USER	(not set)	IMAP username — set automatically by mailtrim setup
MAILTRIM_IMAP_PORT	993	IMAP SSL port
MAILTRIM_IMAP_FOLDER	INBOX	IMAP folder to scan
MAILTRIM_IMAP_PASSWORD	(not set)	IMAP password — never stored on disk, set in your shell

Set AI mode:

mailtrim config ai-mode off     # default — no AI, nothing sent anywhere
mailtrim config ai-mode local   # local models only (Ollama, llama.cpp)
mailtrim config ai-mode cloud   # Anthropic Claude — requires ANTHROPIC_API_KEY

---

Troubleshooting

mailtrim doctor    # diagnoses auth, Gmail connection, storage, config

Symptom	Fix
"Gmail connection expired"	mailtrim auth
"Token file not found"	mailtrim auth
"Cannot write to ~/.mailtrim/"	chmod 700 ~/.mailtrim
"Rate limit hit"	Wait 60s, retry with --max-scan 300
Scan feels slow	mailtrim stats --max-scan 500
Not seeing enough senders	mailtrim stats --scope anywhere
IMAP connection failed	Re-run mailtrim setup to update server/user settings
Switched to Gmail but still prompted for IMAP password	Re-run mailtrim setup and choose Gmail — this clears stale IMAP settings from .env
IMAP undo restores fewer emails than expected	Normal on non-Gmail IMAP — UIDs are folder-specific; check Trash manually for any remaining emails
IMAP purge returns 0 emails moved	Server may lack a Trash folder; run mailtrim doctor to check
