How Ivrnet powers 20M+ critical communications a month with Sinch

Ivrnet is a Canadian communications software company that helps organizations deliver time-sensitive messages at scale. Its clients include municipalities, HOAs, transit authorities, schools, healthcare providers, and utility companies — each needing to reach people quickly, through the channel they prefer.

These messages can be critical: a boil water notice, a school closure, the next bus arrival time, or a payment reminder. Without a reliable, scalable provider, these communications risk being delayed or ignored altogether.

“We support utilities, healthcare, transportation, and education,” explained Jennifer McLean, VP of Operations. “Our clients need to reach people where they are—SMS, WhatsApp, email, or voice—and they want those people to be able to respond comfortably.”

As Ivrnet’s customer base expanded, the complexity of managing multichannel communications required a partner with the scale and infrastructure to keep up.

Not every message is best delivered the same way. A boil water advisory needs the immediacy of SMS. A payment reminder might work better by email for some residents, but text for others. Transit riders want real-time updates they can get on the go, while HOAs often rely on voice notifications for older members. Ivrnet wanted the flexibility to meet people where they are—no matter the channel.

With Sinch’s APIs, Ivrnet enables its clients to send two-way SMS for safety alerts, resident reports, and community watch programs; trigger payment reminders and event notifications with higher response rates; and deliver real-time transit updates based on live schedule requests.

“By adding SMS, our clients are finding their response rates quicker, payments are being collected faster, and they’re not seeing as many suspended accounts,” said Jennifer McLean, VP of Operations at Ivrnet.

Sinch also helps Ivrnet manage the essentials of messaging at scale — provisioning local, toll-free, and short code numbers, and registering 10DLC campaigns.

Today, Ivrnet sends 15–20 million communications every month, with Sinch APIs providing the scale, reliability, and compliance needed to make it all happen.

For Ivrnet, finding the right partner wasn’t just about infrastructure. They wanted a team that could grow with them, share insights, and stay closely aligned on strategy.

Sinch delivers that by pairing reliable APIs with ongoing collaboration. The two teams hold regular roadmap discussions, evaluate channel performance, and explore new ways to create value for Ivrnet’s clients. Accessibility and responsiveness from Sinch’s team have been just as critical as the technology itself.

“We have our regular check-ins,” Jennifer said. “We have conversations about growth and development and what our business plans are to make sure that Sinch knows what’s coming and how they can best support us.”

Looking ahead, Ivrnet plans to expand beyond North America and into new industries. With Sinch’s global reach and collaborative support, they’re confident their communications are ready for whatever comes next.
