Dual-Track Classification Engine
MailHelm uses a powerful dual-track classification engine β no AI touches your emails at runtime. The Priority Engine sorts emails by urgency using Urgent, Attention, and Ignore rules. The Mapping Engine assigns categories and moves emails to the right IMAP folders automatically.
- Priority funnel: Urgent > Attention > Ignore > Normal (default)
- 100% rules-based β zero AI at runtime, total privacy
- AI helps write rules from natural language (optional)
- Auto folder mapping β 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

- 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, and folder mappings per account. Use natural language to create rules β AI compiles them into JSON, then steps aside.
- VIP sender lists with auto-priority
- Custom rules with trigger/action logic
- Auto folder mapping per classification
- Follow-up tracking and reminders
