InboxForge

Full Gmail mailbox downloader, AI-powered organizer, and analytics suite. Download your entire Gmail as .eml files, auto-categorize with 150+ domain mappings and Claude AI, then organize locally — without ever modifying your live mailbox.

Features

Core

• Full Mailbox Download — Downloads all Gmail folders (Inbox, Sent, Drafts, Starred, custom labels) as .eml files with original folder structure preserved
• Resumable Downloads — Stop anytime, resume later. Manifest tracks every downloaded email per folder
• Message-ID Deduplication — Same email across multiple Gmail labels stored once on disk
• AI Categorization — 150+ known domain mappings, List-Unsubscribe newsletter detection, subject pattern matching, and Claude Haiku for ambiguous emails
• Dual Execute Mode — Organize local files (safe, no mailbox changes) or apply Gmail labels (modifies live mailbox)
• Feedback Loop — Every manual recategorization teaches the engine. Learned rules persist across sessions and apply first on future runs

Analytics

• Statistics Dashboard — Emails per month, activity heatmap (day x hour), top senders/domains, category distribution, storage breakdown
• Group-by Views — Instantly regroup the tree view by Category, Sender Domain, Sender, or Source Folder

Subscription Management

• Subscription Scanner — Detects newsletters via List-Unsubscribe header + 25+ newsletter platform domains (Mailchimp, SendGrid, Substack, etc.)
• One-Click Unsubscribe — Opens unsubscribe URL directly in your browser
• Frequency Analysis — Shows daily/weekly/monthly/irregular send patterns per subscription

Power Tools

• Auto Clean Rules — Persistent rules engine (domain, sender, subject, age, newsletter flag) with CRUD editor
• Gmail Filter Import — Parse Gmail's filter export XML into InboxForge rules
• Attachment Extraction — Pulls all attachments from .eml files, deduplicates by SHA-256, organizes by category
• Sensitive Content Scanner — Detects SSNs, credit card numbers, passwords, API keys, and tokens in email bodies
• Thread Summarization — Reconstructs email threads via In-Reply-To/References headers, generates 2-3 sentence AI summaries
• CSV/JSON Export — Full metadata export (date, sender, subject, category, confidence, folder, size, newsletter flag, sensitive flags)
