Everything fax should have been.
Not a dumb pipe — a platform that turns the documents you receive into work that actually gets done.
Workflows
Bring the logic of a call queue to fax. Inbound documents are routed by sender or content, assigned to the right person, given an SLA, and tracked to done — nothing sits in a shared inbox no one owns.
Smart Fax
Send a form and get back structured data, not a PDF to re-type. Sanga matches the return to the original, reads the fields, validates them, and pushes the data into your systems automatically.
Sanga, your fax AI
Every inbound fax is summarized, classified, and filed. Ask questions across your entire archive, draft cover sheets, and let routing rules run themselves.
A real inbox
Shared and personal folders, auto-filing by customer or vendor, retention policies, and full-text search across everything.
Carrier-grade delivery
Reliable send and receive with automatic failover and page-level delivery tracking. No dropped pages, no mystery.
Secure by design
Encryption, a complete audit trail, and an optional HIPAA tier for teams that need it — without burdening teams that don't.
Threaded conversations
Replies stitch to the original automatically, so a request and its response live together. Stop chasing related faxes.
Numbers & porting
Request a new number or bring your own with a guided, signed letter of authorization — and watch the status live.
Built to connect
A clean API and webhooks so rwrFax fits the tools you already run, from your CRM to your record system.
