Why Jasni
Not another inbox.
Email infrastructure for agents.
Traditional inbox tools are built for humans: mixed threads, unpredictable state, no way to track what's been handled. Jasni treats email as first-class structured data, built from the ground up for automated workflows.
Mixed threads impossible to parse programmatically
Unpredictable state with no way to know what's handled
Tied to individual human accounts and credentials
Easy to burn domains with naive automation
Clean, structured threads you can reason about
Explicit state & metadata for every email
Scalable identities, not tied to human accounts
Safe automation patterns that protect your domains
Structured Data
Every email is clean JSON. Threads, metadata, and attachments, all queryable.
Explicit State
Track what's read, replied, or pending. Your agents always know the status.
Scalable Identity
Spin up inboxes on demand. No OAuth tokens or human account limits.
Safe Automation
Built-in protections keep your domains and sender reputation safe.
