What Makes TNZ Different

TNZ isn't just a tool for sending messages. It's a flexible communication hub built to fit into your existing systems. Some teams connect their calendar or CRM and automate everything behind the scenes. Others use the dashboard daily to send messages, manage contact lists, or coordinate across departments.

Big or small, technical or not, TNZ is built to work your way.

How TNZ Works: One Platform, Flexible Options

TNZ brings together SMS, email, voice, fax, and instant messaging into one simple, powerful platform. Whether you're sending reminders through your dashboard, triggering messages from a calendar, or building automated workflows with your development team, TNZ gives you the flexibility to work your way.

You don't have to choose between technical depth and ease of use. TNZ is designed for both. It's smart enough for developers and accessible enough for busy teams who just want things to work.

Choose How You Send: Dashboard, Apps or API

You can use TNZ entirely from your browser, with no software to install. The web dashboard makes it easy to send one-off messages, create templates, view replies, and manage your communications in one place.

Or, if you're running everything from a CRM or internal system, you can connect via our unified API. This gives you complete control behind the scenes, whether you're sending appointment reminders, emergency alerts, or system notifications. Some teams never log in to the dashboard at all - they let TNZ run quietly in the background.

The point is, you choose what fits your workflow. Nothing is locked in. You can start simple, then add automation or integrations as you grow.

Build Workflows with Smart Triggers and Automation

Need to send a follow-up SMS if your email isn't opened? Want to trigger reminders based on calendar events or CRM fields? With TNZ, that's all possible, and it doesn't require a team of developers.

You can create smart workflows using "if-this-then-that" logic. For example, you might:

  • Trigger a voice call if an SMS goes unanswered
  • Schedule reminders automatically based on Outlook or Google Calendar entries
  • Log replies back into your CRM for tracking

Whether you prefer to set things up visually or use API calls and webhooks, TNZ gives you the tools to automate communication in a way that fits your business.

Designed for Technical and Non-Technical Teams

Not everyone on your team needs to be technical to get the most from TNZ. The platform is built to support a wide range of users, from frontline staff to IT teams.

Admins and coordinators can manage communication through the dashboard, while developers can automate messages, pull reports, and build integrations using our REST API. There's no need to compromise ,TNZ is both powerful and approachable.

Control Everything from Your Communication Dashboard

The TNZ dashboard gives you a full view of your communication in one place. You can set up message templates, store and manage contacts, schedule messages, and monitor delivery and engagement across every channel.

See who replied, which emails were opened, and what messages bounced - all without needing to switch between tools or platforms.

For businesses that want visibility and control without complexity, this dashboard becomes the heart of your communication setup.

Scale as You Grow - Use Only What You Need

You don't have to use everything at once. Start with SMS or email. Stay there if that's all you need. Or expand into multi-channel communication as your needs change.

TNZ is flexible enough to support small teams running simple reminders, and robust enough for enterprise-grade messaging at scale. Some clients use only our email-to-SMS gateway. Others manage thousands of automated interactions across departments. However you grow, TNZ grows with you.

Built for How Your Team Works

TNZ is a single platform that adapts to the unique needs of every team, from marketing and sales to developers and operations.

For Marketers & Business Owners

Use our intuitive dashboard and no-code integrations like Zapier and HubSpot to manage campaigns, automate reminders, and track results—no technical help required.

For Developers & IT Leaders

Integrate SMS, Email, Voice, and Fax with our single, unified REST API. Get clear documentation, robust SDKs, and webhook support for total control and scalability.

For Operations & Critical Teams

Rely on our local, telecommunications-grade infrastructure for mission-critical alerts. Use multi-channel fallback logic and detailed audit trails to ensure your most important messages are always delivered.

The TNZ Advantage: 8 Reasons Businesses Choose Us

One Unified Platform

TNZ combines SMS, email, voice, fax, and instant messaging into a single platform. No more switching tools, reconciling reports, or training staff on separate systems - just one login, one API, and one transparent bill.

One Unified API

Unlike platforms that make you integrate every channel separately, TNZ gives you a clean REST API for all services. Save development time and simplify your messaging stack.

Built-In Automation and Fallbacks

Automation isn't an afterthought. Use triggers and fallback logic like "send SMS if email isn't opened" - all without needing third-party software or coding.

Local Infrastructure and Carrier Routing

Data is hosted in New Zealand or Australia. Messages are routed through trusted local carriers for better speed, deliverability, and compliance.

Expert Local Support, Included

TNZ's support team is based in New Zealand. There's no extra cost, no bots, and no offshore call centres - just real help from people who understand your setup.

Transparent Pricing

Access the platform from $20/month, then pay per use. No bundles, no hidden fees, and no international foreign exchange conversion surprises.

Shortcode and Dedicated Number Support

Need a fast, trusted number for confirmations or campaigns? TNZ handles the entire dedicated number setup for you - with local telco relationships and pricing that makes sense.

Built for the NZ Market

Global tools don't always understand NZ compliance. TNZ is purpose-built to meet the Privacy Act and Unsolicited Electronic Messages Act (UEMA), and we keep your data local.

Inside the TNZ Messaging Suite

TNZ brings together everything you need for modern business communication in one place. Whether you're sending a single message or managing a fully automated workflow, the platform adapts to your needs and scale.

You don't need separate systems for SMS, email, voice, or fax. TNZ combines all of these into a single, flexible platform that fits how your team already works.

SMS, Email, Voice, Fax and Instant Messaging - All in One

The TNZ platform includes five powerful modules, ready to activate as you need them:

  • SMS for reminders, alerts and two-way customer updates.
  • Email for transactional messages like invoices and confirmations.
  • Voice for delivering critical updates that must be heard.
  • Fax for industries requiring secure document delivery.
  • Instant Messaging for connecting with customers via popular chat apps like WhatsApp and Facebook Messenger.

These tools can be used together or independently. Whether you're sending from a CRM, calendar, or directly from the TNZ dashboard, your communication stays connected and under control.

Communication Dashboard: Control SMS, Email and Voice in One Place

The TNZ dashboard is your central control panel. From here, you can:

  • Send one-off or schedule messages across any channel.
  • Create and use message templates.
  • Manage contacts, groups and unsubscribes.
  • Monitor delivery, two-way replies and engagement in real time.
  • Generate reports and export data for analysis.
  • Set user roles and permissions for team members.

It's simple enough for admin teams, but powerful enough for agencies, councils, and enterprise users who need precision and visibility across multiple campaigns.

Build Automated Messaging Workflows with Smart Triggers

TNZ isn't just for sending messages. It's built to automate communication based on real triggers. You can set up workflows that:

  • Trigger messages based on calendar events, CRM updates, or status changes.
  • Set fallback rules across SMS, email and voice.
  • Ensure your most important messages are seen, no matter the channel.
  • Manage contacts and preferences based on behaviour.

Need to send a follow-up SMS if an email isn't opened? Want to trigger a voice alert after a missed appointment? TNZ makes it easy to automate common workflows without needing third-party software or custom scripts.

Automation isn't a bolt-on. It's built into the core of the TNZ platform - ready whenever you are.

Use Only What You Need

Some teams rely entirely on the dashboard with saved templates and contact lists. Others prefer to connect through the REST API and let their systems handle everything behind the scenes. You might start with SMS and add email or voice over time. However you want to communicate, TNZ fits into your existing workflow.

You don't have to switch platforms as your needs grow. With TNZ, everything is already built in.

SMS with TNZ: Fast, Flexible, and Built for Business

SMS is often the first step for businesses looking to modernise how they communicate - and for good reason. With open rates above 90 percent and delivery in seconds, SMS cuts through the noise and delivers your message when it matters most.

Whether you're reminding customers about appointments, sending time-sensitive updates, or reducing admin load with automation, TNZ makes SMS simple to implement and powerful to scale.

Why Start with SMS?

Most businesses already know they need to use SMS, but aren't sure where to begin. TNZ is built for this starting point. We help you:

  • Replace follow-up phone calls with automated reminders.
  • Interact with your existing systems.
  • Track replies, confirmations, and opt-outs in one place.
  • Build smart workflows without needing a full IT overhaul.

It starts with a single reminder - and often grows into something far more powerful.

Common Business Use Cases

SMS can be adapted to almost any customer-facing or internal communication need. Popular examples include:

  • Appointment reminders - "Your appointment is on Tuesday at 10am. Reply Y to confirm."
  • Pick-up notifications - "Your glasses are ready for collection."
  • Annual check-ins - "Your vehicle is due for service. Book online now."
  • Payment and service updates, time-critical notices, or internal alerts - "Your payment has been processed successfully."

Because SMS integrates easily into your daily tools, these use cases can be set up quickly and scaled as needed.

The Power of Two-Way SMS Messaging

TNZ supports two-way SMS so customers can reply to your messages and interact naturally. This is ideal for reducing missed appointments and increasing responsiveness.

  • Replies like "Y" or "N" can automatically update your system
  • Messages and replies are logged in your TNZ dashboard
  • You can forward replies to email, CRM, or other tools
  • Creates a transparent, auditable communication trail

This is what turns SMS from a one-way alert system into a real engagement channel.

Easy Integration with Your Existing Tools

You don't need to change your software or your team's workflow. TNZ works alongside the tools you already use, including:

  • Google or Outlook calendars - trigger reminders directly from events
  • CRMs like HubSpot, Pipedrive, and GoHighLevel - send updates from client records
  • Spreadsheets - upload filtered lists and send bulk messages via Excel
  • Custom systems - connect via API for automated messaging

Whether you use no-code tools or custom-built platforms, TNZ integrates with minimal setup and maximum flexibility.

Built for Compliance and Scale

TNZ's SMS service is designed for professional use, not marketing spam. That means your messages are:

  • Delivered via local telco routes for speed and reliability
  • Hosted securely in New Zealand or Australia
  • Compliant with NZ's Unsolicited Electronic Messages Act
  • Supported by automatic unsubscribe handling to keep you covered

Whether you're sending 20 messages or 20,000, TNZ makes sure they land safely - and legally.

Email with TNZ: Reliable Delivery for Critical Messages

When your emails really need to land, invoices, booking confirmations, service alerts, TNZ helps you deliver them without fail. Unlike generic email systems that aren't built for volume or reliability, TNZ is designed specifically for transactional and business-critical communication.

Why Email Deliverability Matters

Not all email services are built the same. Platforms like Gmail or Outlook are fine for everyday correspondence, but they often fall short when used for high-volume or time-sensitive messages. Emails may get delayed, blocked, or land in the spam folder without warning.

TNZ fixes that by focusing on deliverability from the ground up. Your messages are sent from trusted, NZ-based infrastructure that's built for speed, security, and compliance.

Built for Transactional Communication

Whether you're a clinic sending appointment confirmations, a service business delivering invoices, or an enterprise managing alerts and updates, TNZ ensures your messages are delivered as intended.

Common use cases include:

  • Appointment confirmations and booking reminders
  • Invoice delivery and payment alerts
  • Emergency notifications and service disruptions
  • Account updates, password resets, or security alerts

These messages are essential. TNZ helps you send them with confidence.

Deliverability Without the Technical Hassle

You shouldn't need to be an email expert to get your messages into inboxes. TNZ manages all the complex background processes for you, including:

  • SPF, DKIM, and DMARC authentication
  • IP reputation and warm-up protocols
  • Bounce and delivery monitoring
  • Inbox placement strategies

Our team handles setup and technical support, so you can focus on your communication - not your configuration.

Multiple Ways to Send

You can choose the method that suits your team:

  • Use the TNZ dashboard for one-off messages or reusable templates
  • Integrate via our Email API for automated transactional messaging
  • Connect your CRM or internal system to send messages directly
  • Add SMS or voice fallbacks if an email isn't opened

You get full flexibility with none of the lock-in. Whether you're just getting started or managing thousands of messages per day, TNZ helps you scale smoothly.

Voice Broadcast Messaging with TNZ: Be Heard When It Matters Most

Sometimes a text or email isn't enough. For urgent, high-stakes communication, voice messages offer clarity, cut-through, and urgency. TNZ's voice messaging services are built for serious use, trusted by healthcare providers, local councils, aged care facilities, and critical response teams across New Zealand.

Why Use Automated Voice Messaging?

Voice is one of the most effective ways to deliver a message that can't be missed or ignored.

  • It's immediate - people pay attention when the phone rings
  • It's clear - ideal for urgent, time-sensitive information
  • It's accessible - helpful for vulnerable or offline audiences

If your message truly matters, voice makes sure it's heard.

Common Use Cases for Voice Communication

Voice messaging is ideal for:

  • Emergency alerts from councils (e.g. weather warnings, boil water notices)
  • Critical service disruptions
  • School notifications and closure updates
  • Aged care check-ins and medical reminders
  • Urgent payment or account notices

Whether you're reaching hundreds of people at once or delivering a one-to-one update, voice ensures the message is received clearly.

Smart Voice Automation

TNZ lets you send voice messages manually or as part of an automated workflow. You can:

  • Send pre-recorded audio or use text-to-speech
  • Trigger voice calls when an SMS or email is not opened
  • Schedule calls or activate them based on CRM data or calendar events
  • Log and report every message for transparency

This makes voice a perfect secondary channel in multi-step communication processes.

Secure, Local, and Auditable

All TNZ voice services are hosted within New Zealand or Australia. Your calls are:

  • Logged and time-stamped
  • Securely transmitted and recorded
  • Fully reportable for compliance and audit trails

This gives you peace of mind when delivering messages where accuracy, security, and timeliness are essential.

TNZ Virtual Fax: Send and Receive Secure Faxes Online

Faxing is still a critical part of communication in industries like healthcare, legal, and finance. But that doesn't mean you need to be tied to a physical machine. TNZ's Virtual Fax service brings faxing into the cloud era - making it easier, faster, and more secure for modern businesses.

With TNZ, you can send and receive faxes online through your email, the web dashboard, or via API. No phone line, no paper, and no fax machine required.

Built for Compliance and Security

TNZ Virtual Fax is designed for organisations where security and confidentiality matter. Your faxes are:

  • Encrypted in transit and at rest
  • Delivered via secure NZ and AU hosting
  • Logged and tracked with full delivery confirmation
  • Compliant with local privacy and industry standards

It's the ideal solution for professionals who need fax capability without the overhead or risk.

Frequently Asked Questions

Here are answers to some common questions. If you don't see your question here, feel free to contact our support team.

No. Many users never log in to the dashboard at all. Instead, they connect TNZ to their calendar, CRM, or internal systems and let automation do the work. The dashboard is available if you want visibility, templates, manual sending, or reporting - but it's completely optional.

Yes. You can activate only the services you need. Many customers start with business SMS and later add email, voice, or fax when the time is right. TNZ is built to grow with you.

Absolutely. TNZ integrates with most major CRMs, booking tools, and internal systems. You can send messages using API calls, calendar notes, spreadsheet uploads, or even email-to-SMS.

That's no problem. Replies can be forwarded directly to your inbox, viewed in the TNZ dashboard, or pushed to your system using a webhook. You choose what works best for your team.

No. TNZ operates on a monthly subscription with no lock-in contracts. You can start, pause, scale, or cancel at any time.

Support is included with all plans. TNZ's support team is based in New Zealand and available by phone or email. We help with everything from setup to integrations and technical questions.

Yes. All data is hosted in New Zealand or Australia, and TNZ is built to meet local regulations including the Privacy Act and the Unsolicited Electronic Messages Act (UEMA).

Yes. TNZ regularly helps businesses migrate from other platforms. We can assist with moving your templates, contact lists, and workflows so the transition is smooth and stress-free.

SMS FAQ

SMS marketing is a way to reach your customers by sending text messages directly to their phones. These messages can be used for promotions, updates, reminders, or service alerts. With TNZ, you can send SMS messages manually, in bulk, or automatically through your CRM, calendar, or API.

Bulk SMS marketing means sending the same message to a large group of recipients at once - such as a campaign, seasonal update, or critical alert. TNZ lets you upload contact lists, personalise messages, and track results in real time.

Start by identifying the types of messages you want to send - appointment reminders, promotions, service updates, or alerts. Then choose how you want to send them: directly from the TNZ dashboard, through email-to-SMS, or by connecting your CRM or app via API. TNZ makes it easy to start small and scale as you go.

Yes - as long as you follow the rules. The Unsolicited Electronic Messages Act (UEMA) requires:
  • You have consent from recipients to receive messages (they have filled in a consent at sign-up or have inferred consent by purchasing a product or service);
  • You include a clear opt-out option in every message (such as the industry accepted "reply STOP to OptOut");
  • You identify yourself as the sender (your business name or brand must be clearly stated in the message).
TNZ is designed to help you comply with these regulations, with features like opt-out management and local data hosting.

Yes. Our powerful REST API is the core of our platform, giving developers total control to integrate SMS, Email, Voice, and Fax communications into any application. We provide comprehensive documentation and libraries for popular languages like Node.js, Python, and .NET to help you get started quickly.

All features available in our dashboard are also accessible via the One API.

Absolutely. Our platform is built for integration. For business users, we offer no-code connections to thousands of apps via Zapier, allowing you to automate workflows in minutes. We also have native integrations with key platforms like HubSpot, letting you send SMS directly from your CRM.

Our platform provides real-time, transparent delivery reporting. From the One Dashboard, you can track the status of every message—sent, delivered, or failed—with detailed logs. For developers using the API, we provide immediate status codes and can push real-time delivery receipts to your application via webhooks, giving you total control and visibility.

Yes, two-way SMS is a core feature of our platform. You can lease a dedicated number from us to receive replies. Incoming messages can be viewed in our dashboard, forwarded to your email address, or processed automatically by your application via an API webhook. This is ideal for appointment confirmations, customer support, and interactive campaigns.

The Sender ID is the name or number that appears on a recipient's phone. In New Zealand and Australia, you can often set this to your brand or company name (up to 11 characters) for one-way marketing or alert messages. For two-way conversations, a dedicated mobile number is required. Our platform gives you full control to manage Sender IDs to suit your needs.

A standard SMS message is limited to 160 characters. However, our platform supports message concatenation, which automatically links longer messages together. They will appear as a single, seamless message on the recipient's phone. You are billed per 160-character segment sent.

TNZ offers simple, pay-as-you-go pricing with no setup fees or fixed monthly commitments for standard accounts. You only pay for the messages you send. Our pricing is transparent and highly competitive, built on our direct carrier relationships in New Zealand and Australia. For detailed rates and volume discounts, please see our pricing page or contact our team.

While global providers offer SMS, TNZ is the trusted local layer for mission-critical communications in New Zealand and Australia. We offer superior deliverability through our deep understanding of local carrier networks, onshore infrastructure for data sovereignty, and expert, NZ-based support. Our unified platform provides SMS, Email, and Voice through One Dashboard and One API, simplifying your communications stack.

Email FAQ

Transactional emails are one-to-one messages triggered by a specific user action - like booking a service, resetting a password, or receiving an invoice. These are not marketing messages. They deliver information the recipient is expecting, and they often need to arrive immediately.
`

Transactional emails are sent to individuals and contain personalised information (e.g. a receipt or reminder). Marketing emails are sent to a group and promote an offer or event (e.g. a sale or newsletter). TNZ focuses on reliable, compliant delivery of transactional email, with optional SMS or voice backup for time-sensitive cases.

No. You can send messages using the TNZ dashboard, upload templates, or schedule follow-ups - no code required. Developers can also use our API for full automation and system integration.

Our platform is built for flexibility. For developers and system administrators, you can connect your applications using our modern REST API or via standard SMTP Relay. This gives you total control and automation for sending transactional emails like invoices, alerts, and password resets directly from your existing software and systems.

Standard email providers (like Microsoft 365 or Google Workspace) are designed for person-to-person communication, not for automated, high-volume sending. Sending transactional emails through them can lead to poor deliverability, daily sending limits, and even getting your domain blacklisted as spam. TNZ’s platform is purpose-built for high-volume, mission-critical email, ensuring your messages are delivered reliably and your sender reputation is protected.

Deliverability is our top priority. We help you protect your sender reputation by providing tools to set up essential authentication records like SPF, DKIM, and DMARC. Our New Zealand-based infrastructure, managed IP addresses, and proactive monitoring of sending practices ensure high inbox placement rates. We handle the technical complexity so your critical communications are trusted by receiving email servers.

Yes, and we highly recommend it. Sending from your own authenticated domain (e.g., alerts@yourcompany.co.nz) builds trust and brand recognition with your recipients. Our One Dashboard provides a simple, step-by-step guide to help you authorise your domain for sending through our platform, strengthening your deliverability from day one.

Yes. Our platform provides real-time engagement tracking. You can monitor delivery rates, bounces, opens, and clicks directly from the dashboard or receive this data via API webhooks. This gives you clear visibility into how recipients are interacting with your critical communications.

This is where the power of our unified platform comes in. Because TNZ handles SMS and Voice on the same platform, you can build intelligent fallback logic. Using our One API, you can set up rules to automatically send an SMS alert or trigger a text-to-speech voice call if a critical email bounces or isn't opened within a specific timeframe. This ensures your mission-critical messages always get through, no matter the channel.

Voice broadcast is the process of sending a voice message to multiple recipients at once. This can be done using pre-recorded audio or text-to-speech. It's commonly used for emergencies, reminders, and time-sensitive alerts. TNZ supports voice broadcasting through the dashboard, API, or automation tools.

Use voice when your message is urgent, time-critical, or needs to be heard clearly. Voice is especially effective for:
  • Emergency alerts (e.g. weather warnings, safety instructions);
  • Service outages (e.g. internet or power outages);
  • Payment reminders (e.g. overdue invoices);
  • Two-factor authentication (e.g. account security codes and number validation);
  • School and Aged Care check-ins.
Voice messages are more likely to be noticed and acted upon quickly compared to SMS or email, which can be overlooked or delayed.

SMS or email can be missed - voice makes sure the message is heard.

Yes. With TNZ, you can automate voice messaging using:
  • Calendar notes (e.g. Google or Outlook);
  • CRM updates or triggers (e.g. HubSpot, GoHighLevel, Pipedrive);
  • Fallback login (e.g. fallback to voice if the SMS isn't replied to);
  • Apps (e.g. use middleware apps like Zapier and Make.com to trigger calls);
  • Email-to-Voice (a simple email can trigger a voice call);
  • API calls from your application.
This allows you to send timely, relevant voice messages without manual intervention.

Our Text-to-Speech (TTS) engine instantly converts written text into natural-sounding human speech. Simply type your message in the dashboard or send it via our One API, and our platform will make the call and speak the message aloud. This is incredibly powerful for sending dynamic, personalised alerts (like a unique verification code, customer name, or specific outage location) without needing to pre-record any audio.

You have full control over the Caller ID (the number displayed on the recipient's phone). You can set it to a TNZ virtual number you lease from us, or to your existing business landline or mobile number. We complete a simple verification process to ensure you own the number before enabling it as a Caller ID.

Our platform has built-in Answering Machine Detection. You have total control over the behaviour: you can configure the system to leave the message on voicemail, or to hang up and register the call as 'unanswered'. This allows you to tailor your campaigns, for example, by automatically re-trying all unanswered numbers after a set period.

Yes. You can configure voice calls to accept keypad input (DTMF tones). For example, you can ask a recipient to 'Press 1 to confirm receipt of this message' or 'Press 2 to be connected to the on-call technician.' The results are captured in real-time in your dashboard and via the API, giving you a complete audit trail of who has acknowledged your alert.

Our One Dashboard provides detailed, real-time reporting for all voice campaigns. You can see at a glance which calls were answered, unanswered, went to voicemail, or failed. If you have included keypad options, you can also see a breakdown of the responses. All this data is also available via our API for direct integration into your systems.

A virtual number (also known as a local number or DDI) is a regular phone number that isn't tied to a physical phone line. Instead, it uses our network to intelligently divert incoming calls to one or more destinations, such as your mobile phone, a colleague's phone, or even an international number. It provides a professional, local presence for your business without the need for expensive hardware.

Businesses use our virtual numbers to:
  • Present a professional image with a dedicated business landline number.
  • Separate work and personal life by keeping your personal mobile number private.
  • Manage calls as a team by diverting one number to multiple mobiles simultaneously or in sequence.
  • Never miss a call with smart fallback and voicemail-to-email options.
  • Establish a local presence in different cities without needing a physical office.

Fax FAQ

A virtual fax lets you send and receive faxes online without using a fax machine or phone line. With TNZ, you can fax directly from your email, dashboard, or API. Faxes are delivered securely and arrive as PDF attachments.

While TNZ doesn't offer free faxing, TNZ does offer affordable virtual faxing designed for secure, compliant document transmission, especially in healthcare, finance, and legal industries.

Yes. With TNZ, you can send a fax by emailing the document to a special address that routes it through our secure platform. You can also receive faxes into your email inbox as PDFs.

Yes. You can port your existing fax number into TNZ and continue using it with our virtual system. Or we can provide a new local or toll-free number to suit your needs. We provide fax numbers in New Zealand, Australia and a handful of international locations.

Yes, security is at the core of our platform. Unlike a traditional fax machine that can leave sensitive documents in a public tray, our service transmits faxes over encrypted connections. Faxes you receive are delivered directly to your authorised email inbox as private PDF files. All data is securely hosted in our New Zealand-based data centres, helping you meet local data sovereignty and privacy requirements.

Our platform provides complete delivery confirmation. For every fax you send, you'll receive a detailed confirmation receipt via email, which acts as your proof of transmission. In the One Dashboard, you can view a full history of all sent and received faxes, including their status, page count, and duration. This provides a clear and permanent audit trail for your records.

Absolutely. Our One API allows your developers to integrate secure fax sending and receiving directly into your business applications, such as patient management systems, legal software, or accounting platforms. This enables fully automated workflows, saving time and reducing the risk of manual error for routine document transmission.

API & Developer FAQ

An SMS API is a tool that allows your app, CRM, or website to send SMS messages programmatically. TNZ offers a unified API that supports SMS, email, voice, and fax - all through one simple integration.

TNZ provides 25 free test credits so developers can trial the API without payment. For live use, messages are billed per send - with no contracts or upfront fees.

Yes. TNZ integrates with platforms like HubSpot, Pipedrive, and GoHighLevel. You can trigger messages directly from contact records, automate reminders, or log replies back into your system.

Yes. TNZ's API includes real-time delivery tracking, webhook notifications, and full reporting tools. You can track message status, response rates, and costs, down to the subaccount level.

Our One API is a modern, developer-friendly REST API that uses standard HTTP methods and returns predictable, JSON-formatted responses. It's designed for logical and straightforward integration. You can find comprehensive documentation, including code examples and an OpenAPI specification, on our developer portal.

Yes. To help you get started quickly, we offer official libraries for popular programming languages, including Node.js, Python, and .NET. These libraries simplify authentication, message sending, and response handling, allowing you to integrate our platform's power with just a few lines of code. You can find them on GitHub and package managers like npm and pip.

Our platform uses webhooks to push real-time data to your application. You can configure a URL in your dashboard, and we will send an HTTP POST request to it instantly when you receive an incoming message (e.g., an SMS reply) or when the delivery status of a sent message changes. This is a highly efficient method that eliminates the need for your application to constantly poll our API for updates.

Our One API gives you total control over your entire communications workflow. Beyond sending and receiving messages across all channels, you can programmatically manage your address book, handle opt-outs, pull detailed reports, manage users, and provision new sub-accounts (for Partners). Essentially, any action you can perform in the dashboard can be automated via the API.

Yes. This is a key strength of our unified platform. With a single API call to our Workflow endpoint, you can orchestrate sophisticated communication sequences. For example, you can define a workflow to send a critical alert first as an email, then follow up with an SMS if it's not opened within 10 minutes, and finally trigger a text-to-speech voice call if there is still no response.
