Real estate is, at heart, a messaging business. Every listing generates dozens of touches: vendor weekly updates, open-home reminders, buyer enquiry responses, price-reduction notifications, auction follow-ups, settlement chasers. Most of them are SMS. All of them have to feel like the agent personally wrote them, because clients are making the biggest purchase of their life and a shortcode just won't cut it.
ATTIA Real Estate runs on exactly that principle. And until inst8, the agency was paying every per-message rate the available NZ providers wanted to charge for the privilege.
The real estate messaging problem.
A New Zealand real estate agent moves through a predictable arc with each listing: vendor sign-up, photography, listing live, open homes (often two or three per week), buyer enquiries, offers, negotiations, sale, settlement. The communication volume scales with the listing pipeline. A busy agent will easily push thousands of SMS in a month.
Two-way SMS in New Zealand has always been the awkward middle of the messaging market. Twilio doesn't offer two-way SMS in NZ at all. The local providers that do, charge a premium that scales painfully with volume. Industry-standard NZ outbound rates sit around USD $0.0524 per SMS. At ATTIA Real Estate's pace, that's somewhere between USD $400 and $500 a month in carrier fees alone, before any platform subscription, before any photography or marketing, just to send the messages.
More importantly, because those messages came from a real NZ mobile number, buyers and vendors reply. They call back. They expect the conversation to be with their agent, not with a platform.
Why inst8.
Shady Attia set the agency up on inst8 in December 2024 and sent the first message four days later. The setup is the simplest version of what the gateway supports: one Android phone, one local NZ SIM on One NZ, plugged into the CRM the agency already runs on. Outbound SMS flows out the SIM; inbound replies route back to the same threads.
No shortcode registration. No per-message billing. Just a real NZ mobile number running through real infrastructure, sending real messages — and, importantly, receiving real ones back, which most of the 2-way SMS options available in New Zealand can't match at any price.
“Great service and exceptional value. The integration with our CRM was simple to set up and the support team was very helpful.”
ATTIA's savings, in real terms.
Seventeen months in, the savings versus the available NZ alternatives are substantial for a single-device deployment.

All figures in USD. Calculated at USD $0.0524 per outbound SMS, the industry-standard NZ rate (Twilio's published one-way rate; Twilio doesn't currently offer two-way SMS in New Zealand, and the NZ providers that do charge similar or higher rates). Compared to inst8's flat USD $47/month Starter plan over 17 months.
For a boutique agency, USD $6,000 back in the business over 17 months is real money. It's marketing budget, or photography, or settlement gifts, or just margin.
Why a real NZ mobile number matters.
In residential real estate, the message that converts is the one that reads like a person sent it. A reminder from +64 21 … on One NZ looks like the agent. A shortcode looks like a marketing list. Vendors and buyers reply to the former and ignore the latter.
Two-way matters even more in a sales-driven business. About one in fourteen messages on Shady's account is an inbound reply: buyers asking questions about a property, vendors checking on a price reduction, attendees confirming they'll be at the open home. Each of those is a thread that lives back in his CRM, attached to the right contact, ready for the next move.
“My clients reply to me, not to a platform. That's the whole game in real estate. inst8 lets us run at the volume of a much bigger team without ever losing the personal touch.”
What's next.
Seventeen months in, the setup hasn't changed. One device. One SIM. One number. The same flat fee. The volume keeps climbing.
For inst8, the ATTIA Real Estate story is the version of the gateway thesis that's hardest to argue with. A boutique agency, in the country we built this in, running the kind of high-trust personal messaging that real estate genuinely depends on — and keeping nearly seven thousand US dollars that two-way SMS in New Zealand would otherwise have cost.
