Self-hostable OSINT platform for investigating email addresses. Fan out across breach databases, social networks, DNS records, and the open web — get back a unified exposure score and structured findings you can export or pipe into Maltego.
Built for security researchers, OSINT analysts, and penetration testers operating under authorization. Read DISCLAIMER.md before use.
Terminal Output
Install
pip install mailaccess
mailaccess investigate you@example.com
The CLI auto-starts and stops the backend for each investigation. Use
mailaccess serve when you want a persistent server, or install
mailaccess[ml] for optional spaCy-based name classification.
Full install options (Docker, persistent server, self-hosting) -> docs/self-hosting.md.
Quick Start

What It Does
- Identity graph - cross-platform correlation of accounts, usernames, names, avatars, breach data, and profile links.
- Name Consensus Engine - synthesizes independent name signals into confirmed, probable, possible, or unknown identity bands.
- Defender's Brief - security-manager-ready risk summary with prioritized findings and a concrete next action.
- Domain email harvesting -
harvest-emailsdiscovers organization addresses across Common Crawl, GitHub, CT logs, registries, keyservers, dorks, employee pages, and patterns. - 2500+ platform coverage - native Maigret engine plus Sherlock, Nexfil, Blackbird, WhatsMyName, Holehe, and user-scanner coverage.
- Deep breach mode - probes the highest-severity breach corpus for account-existence risk.
- Credential Risk Score - separate 0-100 credential exposure band with top drivers and recommended next steps.
- 6 export formats - JSON, CSV, PDF, Markdown, STIX 2.1, and Maltego XML.
Identity Graph
Every investigation builds an identity graph linking accounts by shared usernames, photos, display names, and breach data. View it at /investigation/:id/graph, export it with GET /api/report/{id}/graph, or read the full model in docs/modules.md.
Name Consensus Engine
MailAccess collects name signals from profile modules and returns a defensible identity summary:
CONFIRMED IDENTITY
Name: Katriel Moses [CONFIRMED]
Sources: GitHub . Gravatar . Keybase . PGP
Reasoning: 4 independent sources agree.
Full confidence rules and source behavior -> docs/modules.md.
Defender's Brief
Every investigation includes a 30-second risk summary designed for security managers:
DEFENDER'S BRIEF
Risk: CRITICAL
Summary: Active infostealer infection detected.
1. Active credential theft [CRITICAL]
-> Rotate credentials immediately.
Next action: Immediately rotate credentials and enforce hardware MFA.
Suppress it with --no-brief; full details live in docs/modules.md.
Modules
64 modules, 2500+ platforms by default. Full module reference -> docs/modules.md.
API Keys
Most modules work with zero keys. Optional keys unlock more coverage. Full list -> docs/api-keys.md.
Export Formats
Save reports as JSON, CSV, PDF, Markdown, STIX 2.1, or Maltego XML with -o. Full export reference -> docs/exports.md.
Integrations
Use Maltego, Slack, Discord, generic webhooks, JSONL pipelines, and CI workflows. Full integration guide -> docs/integrations.md.
Self-Hosting
Run the CLI locally or launch the full web stack with Docker Compose. Full guide -> docs/self-hosting.md.
