Everything you need to manage email at scale
People-centric delegation, local-first security, and AI tools that show their work.
Multi-inbox delegation
Group accounts under people. Assign permission tiers — Owner, Full, Triage, or Read — and manage every inbox from one workspace.
Archive ingest
Drop MBOX, PST, OST, or EML files. TwinMail indexes them locally with deterministic progress and checkpoint recovery.
AI tools
Summarize threads, extract entities, and draft replies. Every AI action shows its inputs and outputs in a glass-box pattern.
People-centric views
Switch between Person and Account views. See all conversations for an individual regardless of which inbox they came from.
Vault encryption
Message content stays on your device inside an encrypted Vault. Cloud features require explicit opt-in per action.
Handoff plans
Generate guided action plans to transfer responsibility. Each handoff includes context, next steps, and audit trail.
Three steps to inbox clarity
Connect or import
Add live accounts from any provider or drop exported archive files. TwinMail handles both seamlessly.
Organize by person
Group inboxes under the people they belong to. Set delegation permissions and manage access.
Act with intent
Summarize threads, create handoff plans, and draft replies — all from one calm workspace.
Your email stays yours
TwinMail stores message content locally. Cloud features require explicit opt-in per action.
Local-first architecture
TwinMail stores message content locally on your device. No cloud sync happens without your explicit action.
Vault encryption
Each data boundary is an encrypted Vault. Your messages, metadata, and search indices remain under your control.
Explicit consent model
Cloud features require explicit opt-in per action. We show what data leaves the device and where it goes.
