nothx

nothx (no thanks) separates legitimate subscriptions from spam and phishing, then takes the safe action: unsubscribe from authenticated lists or suppress dangerous mail in Junk without contacting its sender. Mailbox access and body inspection stay on your machine. If you enable a cloud AI provider, only a bounded summary of locally selected marketing/spam headers is sent for preference classification—never message bodies or unrelated personal mail.

Your inbox, uncrowded.

Quick Start

pipx install nothx
nothx init

The wizard configures accounts and AI. Outlook/Live/Hotmail also requires the one-time Microsoft application setup described below.

Don't have pipx? brew install pipx (macOS) or sudo apt install pipx (Linux).

Run nothx anytime for the interactive menu.

Why nothx?

Features

Core

• AI-Powered — Claude, GPT, Gemini, or local models via Ollama
• Authenticated Unsubscribe — strict RFC 8058 one-click, vetted HTTPS GET, or constrained mailto
• Real Spam Suppression — consumes provider Junk/phishing verdicts and safely moves exact IMAP UIDs to the discovered Junk mailbox
• Privacy First — header-only by default; the optional footer scanner is local, bounded, and never sends footer content to AI

Smart

• Learns From You — Gets smarter every time you disagree with a decision
• 5-Layer Classification — Rules → Patterns → AI → Heuristics → Manual review
• Guarded Automation — unknown authentication, conflicting verdicts, and protected identities go to review

Practical

• Multi-Account — Scan Gmail + Outlook simultaneously
• Native Scheduling — No daemon needed. Uses launchd (macOS) or systemd (Linux).
• Future Policy Corrections — nothx undo domain.com changes nothx's future decision; it cannot externally resubscribe you

Beautiful

• Rich CLI — Animated banner, progress bars, colored output
• Interactive Mode — Just run nothx for menu-driven operation

The Learning System

nothx gets smarter the more you use it. Every decision trains your personal preference model.

What it learns:

• Keywords — Keep emails with "receipt"? Future receipt-related senders score safer.
• Open rates — If you keep emails you never open, it stops penalizing low engagement.
• Volume tolerance — Keep high-volume senders? It raises the threshold before flagging.

Corrections teach it too. When you run nothx undo, it doesn't just restore — it learns that this type of email matters to you.

How It Works

Email arrives in Inbox or Junk
      ↓
┌─────────────────┐
│ PROVIDER POLICY │  Junk, phishing, authentication, mailbox flags
└────────┬────────┘
         ↓
┌─────────────────┐
│  USER RULES     │  Your exact keep, unsubscribe, and block choices
└────────┬────────┘
         ↓
┌─────────────────┐
│ LOCAL CANDIDATE │  List/bulk, engagement, and cold-outreach evidence
└────────┬────────┘
         ↓
┌─────────────────┐
│ AI / HEURISTICS │  Preference classification for selected candidates
└────────┬────────┘
         ↓
┌─────────────────┐
│ SAFE DISPOSITION│  Keep, review, unsubscribe, or move to Junk
└─────────────────┘

Provider threat evidence and explicit block rules are resolved before AI. Mixed clean/threat or pass/fail evidence requires review; one flagged message never authorizes suppressing the whole sender group. Bulk mail is not automatically spam, and an unsubscribe link is not automatically safe.

Commands

Essentials

Cleanup review focuses on marketing/newsletters and spam. Promotional evidence is checked across every header in the scan, including mail older than the five recent subject samples. Personal conversations and service-only senders stay outside the cleanup picker. Mixed service/promotional senders appear for inspection with promotional examples, while their receipts and security notices continue to prevent group-wide suppression. Search by full sender address, account, mailing list, or subject; pages contain at most 20 sender groups and you can finish review at any time. Accounts and separate mailing lists are never merged by domain. Use nothx cleanup --details for candidate tables before review.

Setup

Requirements

• Python 3.11+
• Gmail, Outlook, Yahoo, or iCloud account
• AI provider (optional — works without AI too)

Installation

pipx is the recommended way to install nothx. It handles virtual environments automatically.

# Base install (heuristics only, or Ollama)
pipx install nothx

# With your preferred AI provider
pipx install "nothx[anthropic]"  # Claude (recommended)
pipx install "nothx[openai]"     # GPT-4
pipx install "nothx[gemini]"     # Google Gemini
pipx install "nothx[all-ai]"     # All providers

brew install pipx

# Ubuntu/Debian
sudo apt install pipx

# Fedora
sudo dnf install pipx

python3 -m venv ~/.nothx-venv
source ~/.nothx-venv/bin/activate
pip install nothx

Safety and privacy defaults

• Inbox and the unambiguously advertised IMAP \Junk mailbox are scanned. nothx does not guess localized Junk folder names; configure an override if your server advertises none or several.
• Ordinary runs repeat the configured lookback (30 days by default), so earlier undecided mail is reclassified after AI or policy changes. --new-only explicitly uses (account, mailbox, UIDVALIDITY, UID) cursors. Full history is explicit: cleanup includes only Inbox, while run --full-history also includes configured folders.
• Marketing/newsletters with at least 25% of messages marked read require review by default. Engaged cold outreach also requires review. Read flags are imperfect evidence of preference, so they never force KEEP. Choose nothx config --engaged-marketing allow to permit automatic actions on clear promotions even when read; explicit keep/block choices still win.
• Every scan reports mailbox size, selected headers, headers read, and scope. A small incremental result describes new mail, not a clean Inbox. Junk messages already outside Inbox are reported separately from Inbox messages to move.
• Cleanup previews show summary counts; add --details for each unsubscribe/block candidate’s account/list identity and recent subjects. Unsubscribe requests stop future deliveries when honored; existing marketing messages remain in Inbox. Block actions move matching messages to Junk. Preview uses configured AI only when enabled; --dry-run remains local.
• Body fetching is disabled by default. The optional footer scanner examines at most two inline text tails (64 KiB each, 128 KiB total) for authenticated list/bulk candidates. It skips attachments, nested messages, images, scripts, and forms.
• One-click POST requires compliant headers plus $canunsubscribe or a correlated passing DKIM signature that covers both unsubscribe headers. All outbound unsubscribe contact—including an explicitly opened browser page—and mailbox actions require separate, versioned consent.
• HTTP requests are HTTPS-only, proxy/cookie/auth/referrer-free, redirect constrained, SSRF checked, and connected to an already validated public IP while preserving TLS hostname verification.
• Stored targets are fingerprints and hashed destination labels. Complete hosts, paths, queries, mailto recipients/bodies, and HTTP response bodies are excluded from normal history and exports.

What an outcome means

• requested: the endpoint accepted a one-click/GET request, or SMTP accepted the mail for delivery. It does not guarantee mail will stop.
• needs_user: automation reached a login, JavaScript flow, preference center, CAPTCHA, or an ambiguous submission. Nothx can submit one same-origin, unambiguous unsubscribe confirmation form; it does not choose preferences or enter credentials.
• verified_quiet: a complete post-grace scan found no later matching delivery.
• ineffective: matching mail arrived after the 48-hour grace period. One fresh-token or alternate-method retry is allowed; another post-grace delivery is blocked.
• blocked: nothx sent no unsubscribe traffic and applied its local spam path. Portable IMAP Junk movement is best effort; provider-side spam training is not guaranteed.

Troubleshooting

nothx reset              # Delete everything
nothx reset --keep-config # Keep accounts, clear history

Comparison

Philosophy

We built nothx because:

1. Your email is yours. Not a product to sell.
2. AI should adapt to you. Not the other way around.
3. Automation should be invisible. Set once, forget forever.
4. Words matter. A request is not verified cessation, and changing local policy cannot externally resubscribe an address.

Sonnet model (September 29, 2026)

The optional Sonnet choice uses claude-sonnet-5-5; the Haiku default is unchanged. Short Sonnet completion paths request between_tools to preserve the output budget; explicit adaptive reasoning remains available. Existing model environment overrides still take precedence.

Finishing saved unsubscribe decisions

nothx review includes failed requests and offers Resolve unsubscribe in Nothx. The equivalent nothx resolve ID refreshes up to 50 stored Inbox sources without being limited to the normal 30-day lookback. It checks UIDVALIDITY, UID, Message-ID, From and list identity before using a source. If the mailbox changed or the messages are gone, run nothx cleanup to refresh the full Inbox history.

Use nothx resolve ID --dry-run to see usable source UIDs without contacting a sender or saving decisions. Mixed From-address groups require a source selection; scripts can pass --source-uid UID --yes. This source-level choice does not set a blanket unsubscribe policy for the sender. Optional nothx config --footer-scan on also lets resolution inspect at most three bounded, authenticated footer sources for alternatives to failed header links. It stays off by default. Full scans spend their 100-message-per-account footer budget on the newest eligible message from distinct subscriptions, so a single prolific newsletter cannot consume the entire budget.

An explicit --retry permits one additional attempt. Accepted requests, ambiguous submissions and exhausted retries are not replayed. Ordinary scans preserve these boundaries. For a provider requiring login or preference choices, use nothx open-unsubscribe ID, complete the provider step, then nothx resolve ID --completed after seeing confirmation. The latter records your reported confirmation, not independent proof of delivery stopping. Nothx waits 48 hours and a complete subsequent Inbox scan before reporting verified quietness.
