Send and receive faxes by API, email, or portal
Experience the next generation of digital faxing. No hardware, no phone lines, just a high-reliability cloud fax platform built from the ground up for high compliance, secure handling, and modern developer workflows.
Free number porting
Outbound email → fax
Staff email a document (PDF/TIFF) to @fax.crazytel.net and it goes out as a fax instantly. Simple, convenient, and requires zero user onboarding.
Outbound API → fax
Perfect for developers. Your application uploads a PDF or TIFF and dispatches faxes via our robust, secure, and idempotent REST API.
Inbound fax → email
Callers fax your dedicated Crazytel number. Our inhouse platform converts it to a high-definition PDF and routes it to your email and the portal.
How It Works
Set up your modern cloud-based fax operations in three simple steps.
Get a Fax Number
Buy premium Australian fax numbers instantly in our portal, or port your existing fax numbers from any Australian provider for free.
Configure Your Routes
Route each number (DID) to a mailbox, department, or webhook. Setup schedule windows (active from/until) and link routes to custom fax service profiles.
Send & Receive Faxes
Send via portal, REST API, or email. Inbound faxes arrive in your inbox as secure, password-protected PDFs or temporary portal download links.

Features Grid
Everything you expect from an enterprise fax platform, natively integrated into a single interface.
Inbound Fax-to-Email
Receive unlimited faxes on our Complete plan. Inbound faxes are captured, compiled, and dispatched as high-fidelity PDF attachments directly to your inbox.
Email-to-Fax
Send faxes directly from your existing email. Support for multiple parsing methods like number@fax.crazytel.net or using subject/body parsing.
REST API
A secure, developer-first endpoint. Perform operations like document upload (PDF/TIFF), idempotency key validation, cancellation, and download links.
Signed Webhooks
Subscribe your applications to live events (Fax succeeded/failed, documents ready, billing holds) secured with cryptographically signed HMAC-SHA256 headers.
Cover Pages & Templates
Create professionally branded cover pages dynamically. Choose from pre-made templates or customize your headers, logo, and legal disclaimers.
Intelligent Smart Retries
Our destination-learning dialer automatically rotates through optimized profiles, handles T.38 / ECM negotiation, and retries busy/unanswered numbers.
Unified Portal & Dashboard
Manage your entire fax infrastructure side-by-side with your API keys and routing configuration in our secure, responsive customer portal.
- Live Dashboard: Instantly view sent/received counts, success rates, pages used, and real-time activity metrics.
- Normalized Status History: View clean, descriptive, customer-safe statuses (e.g., Sent, Failed, Routing) without confusing carrier jargon.
- Visual Usage Meters: Real-time consumption counters show exactly how many of your 100 included pages have been used.
- Administrative Audit Logs: Access logs showing setting changes, cancelled faxes, and secure download requests.
- Setup & Configuration Wizard: Fast on-boarding for linking routes, porting fax numbers, and choosing recipient rules.

Developer-First Fax Infrastructure
Our in-house fax engine features comprehensive API support, live status events, and signed security protocols. Integrate with any CRM, ERP, or clinical system within hours.
Idempotent Requests
Safe-to-retry operations using idempotency keys protect your workflows against duplicate fax dials or multi-billing errors.
Live SSE Streams
Listen to real-time status changes using Server-Sent Events (SSE) streaming connections, showing immediate transmission flow.
HMAC-SHA256 Signatures
Secure endpoints and webhooks. All fax.v1.* event family payloads are cryptographically signed to authenticate source requests.
OpenAPI Documentation
Interactive documentation schemas are published at /docs and available in JSON at /openapi.json for seamless integration.
Administrative Configurations & Controls
Granular controls to handle routing, templates, sender rules, and multiple service workspaces.
Fax Service Profiles
Group settings under custom profiles (timezone, default caller ID, default headers). Enable or disable inbound/outbound individually. Run multiple profiles under one core account.
Advanced Inbound Routing
Link DID fax numbers to target profiles. Route inbound documents straight to email mailboxes or configure webhook callbacks. Apply schedule windows for active routing hours.
Fine-Grained Retry Policies
Customize retry profiles for outbound dispatches. Configure maximum dial attempts, interval times, and partial-page retry policies for lines experiencing noise or drops.
Email Alert & Recipients
Dispatch real-time delivery alerts (success or fail) to multiple internal recipients. Choose between sending the document as an attachment or using short-lived download links.
Attachment Passwords
Strict security for medical and clinical faxes. Ensure inbound PDF attachments are password-protected using a customer-defined password or unique per-fax passcodes.
Allowed Sender Domains
Enforce strict access. Deny open-relay vectors by defining explicit allowed sender email addresses or corporate domains capable of dispatching faxes to our outbound system.
Enterprise-Grade Security & Reliability
Why corporate, healthcare, and legal networks choose Crazytel. We protect data sovereignty and secure transmission lines.
Security & Trust Controls
- IP-Authorized API: Restrict client connections to designated approved corporate IP allowlists. Unauthorized request locations are instantly dropped.
- Secure Artifact Retention: Set customizable data retention durations. Files automatically purge from secure object storage while retaining metadata records.
- Data Sovereignty: Crazytel is 100% Australian owned and operated. No international routing of document content; files remain within Australian-resident datacentres.
- Fail-Closed Design: System automatically blocks sends from unauthorized relays, suspended balances, or unknown routes to lock down leakage vectors.
Carrier-Grade Transmission
- T.38 & ECM Native Support: Advanced VoIP signaling and Error Correction Mode (ECM) minimize packet errors, delivering extremely clean transmission.
- Destination Learning: Our platform tracks successful connections, dynamically applying optimized profiles (speed, modulation) to match receiver equipment history.
- Pre-Dial Document Validation: Rejects encrypted PDFs, oversized file attachments, or unsupported formats before placing calls, saving dial overhead.
- Decoupled Webhook Retries: If notification endpoints fail, the webhook retries on separate queues without compromising the delivered status of the fax.
Tailored for High-Compliance Industries
Our platform handles critical documents with maximum reliability, making it the perfect choice for several key sectors.
Safeguard medical records. Inbound faxes arrive as password-protected PDFs. Combine with auto-delete rules to clear documents off servers instantly on delivery.
Send contracts and disclosures with certified custom cover pages. Audit-log trails map exactly who initiated sends, requested downloads, or edited rules.
Decommission paper fax machines completely. Empower dispersed departments to send faxes directly through email and manage activity in the browser.
Automate business systems. Disbursing invoices, purchase orders, or booking confirmations over API triggers signed webhook receipts for immediate status updates.
Advanced Add-ons & Roadmap
Grow with features designed for automation-heavy networks.
Document Intelligence (Opt-in)
Leverage automated parsing. Extract text content via Optical Character Recognition (OCR), process barcodes, classify document types, and receive safe text metadata directly in webhooks.
International Fax (0011)
Send faxes worldwide seamlessly. Our platform charges a small per-page surcharge while standard international calling rates apply.
Scheduled Dispatching
Queue up faxes for off-peak transmission. Scheduled jobs are supported natively within our API and visual filters let you manage pending sends.
