COMPARE | TNZ AND ETXT

A simpler alternative to Spark eTXT

Spark eTXT handles basic texting, but CRM integration can add separate fees, messages sent to invalid numbers may still be charged, and pricing is available only by quote.

With TNZ, you can keep sending by email-to-SMS or API, then add email, voice, integrations and automated follow-up through the same subscription. Pricing is published upfront: $20 per month plus 10c per text.

eTXT Made Smarter and Ready for More

If you've used Spark eTXT, you already know how effective SMS can be for sending reminders, updates, and quick alerts. TNZ builds on that same simplicity, adding powerful features that save time and give you more visibility over every message you send.

TNZ is a modern Communications Platform as a Service (CPaaS) designed for the demands of the modern New Zealand business, offering SMS, Email, Voice, and WhatsApp through one simple platform.

Pricing

How much does TNZ cost compared to eTXT?

Spark doesn't publish a price. eTXT is quoted on application and scaled to your volume, so you contact a Spark Customer Lead to find out what you'd pay. Their billing page confirms there are setup and monthly fees, that you're charged for messages sent to invalid numbers, and that connecting a CRM adds its own setup fee, monthly fee and message rates on top.

 Spark eTXTTNZ
Published price Quoted on application $20 a month plus 10c per text
Setup fee Yes None
Monthly fee Yes $20
CRM connection Plug-in with its own setup, monthly and message rates Included, 45+ integrations

TNZ's $20 a month plus 10c per text covers the platform, the dashboard, the APIs, integrations, automation, delivery reporting and local support.

What else is different?

The fallback one matters more than it looks. On an SMS-only gateway, a text that doesn't arrive is the end of it. TNZ Workflows can follow an unanswered message with a voice call or an email, so the ones that matter have a second route.

Can you switch without changing how you send?

Mostly, yes.

A tweak to your Email-to-SMS address or API Endpoint is all that's required.

It's the same move whether you're on Spark eTXT, One mTXT or 2degrees GroupText.

Spark eTXT vs. TNZ FAQs

Spark does not publish a standard eTXT price; pricing is provided by quote and varies with message volume.

TNZ publishes its price, $20 a month plus 10c per text, with integrations and support included. See current TNZ pricing.

Yes. Update the email address to use @sms.tnz.co.nz. See the Email-to-SMS.

No. You change the URL endpoint and your access token. The request structure stays familiar, so it's a settings change rather than a rebuild.

Generate an Auth Token for an API-enabled user and send it in the Authorization: Bearer YOUR_TOKEN header. The Auth Token is a long-lived access token, so it does not need to be constantly refreshed; rotate or revoke it when your security process requires.

TNZ automatically assigns a built-in New Zealand short code based on your message type and includes it in your plan. API users do not need to set FromNumber. Choose a dedicated 4-, 5-, or 6-digit short code if you need an exclusive number, inbound SMS at any time, or keyword campaigns.

If you already use a dedicated sender, contact TNZ before cancelling or changing it. The team can review its carrier arrangement and advise whether and how it can be moved.

Yes. TNZ can send delivery results and inbound replies to your application using webhooks, or you can retrieve them through the API.

That's feasible. 200 texts a month is $20, plus the $20 subscription.

Assumes 200 single segment messages sent to New Zealand mobiles, excluding GST.

Yes. The approach is the same: update the Email-to-SMS destination or SMS API endpoint.

TNZ provides delivery results so your application or team can see what happened.

For important communications, TNZ Workflows can use a voice call or email fallback.

Yes. TNZ supports more than 45 app integrations, including CRM and workflow platforms, with integration access included in the subscription. You can also connect through Email-to-SMS, SMPP or the REST API. Browse TNZ integrations to find your application.

Simple use-cases can migrate in an instant.

For more complex migrations, contact the New Zealand TNZ team to review configuration, sender number, opt-outs and cutover timing. This is especially important before cancelling an existing dedicated short code.
