Dual-Track Classification Engine
MailHelm uses a powerful four-layer classification funnel that works with or without AI. The Priority Engine sorts emails by urgency using VIP lists and custom rules. The Mapping Engine assigns categories and moves emails to the right IMAP folders automatically.
- Four-layer funnel: VIP > Ignore > Custom Rules > AI fallback
- Works without AI — rules-based classification out of the box
- Optional AI enhancement (Groq free, Gemini, Claude, GPT)
- Auto folder mapping — new categories get IMAP folders automatically
Unified Multi-Account Dashboard
See all your email accounts in one Kanban-style board. Drag and drop emails between categories, snooze for later, or archive with a click. No more switching between tabs and apps.
- Gmail, Outlook, Yahoo, iCloud, any IMAP
- Kanban board with drag-and-drop
- Per-account color coding
- Real-time sync via IMAP IDLE

IMAP Server-Side Folder Archiving

AES-256-GCM Encryption
All sensitive data is encrypted at rest using AES-256-GCM with PBKDF2 key derivation. Your master password never leaves your device. Auto-lock protects your data when you step away.
- AES-256-GCM authenticated encryption
- PBKDF2 key derivation (100k iterations)
- Auto-lock on idle
- Zero-knowledge architecture
Per-Account Classification Rules
Every email account is different. MailHelm lets you define custom classification rules, VIP senders, folder mappings, and AI behavior per account. The four-layer funnel adapts to your workflow.
- VIP sender lists with auto-priority
- Custom rules with trigger/action logic
- Auto folder mapping per classification
- Follow-up tracking and reminders
