Customer Story
Challenge: Establish a secure, reliable messaging system for government-wide communications
Solution: Partner with Sinch for direct mobile network operator connections
Results: Enhanced delivery reliability and security
Open Government Products (OGP) builds technology solutions to improve public services and address national challenges in Singapore. Through their Postman platform, they enable government agencies to send official communications to citizens via SMS and email.
“Postman’s vision is to build trusted communication channels exclusively for government use, giving Singaporeans confidence that all messages are authentic and official,” explains Tay Paul Hong, Product Manager at OGP.
The Postman platform has over 40,200 government agency users that send millions of messages. Previously, OGP used a messaging provider that didn’t have direct connections to mobile networks, instead routing messages through intermediaries.
This additional layer created security vulnerabilities and reliability issues that weren’t acceptable for critical government communications.
With millions of citizens receiving critical updates through SMS, they needed a more robust solution — one that could connect directly to all four mobile network operators in Singapore while maintaining servers locally for enhanced security.
That’s what led them to Sinch. The solution provided key features such as direct carrier connections, local infrastructure, comprehensive analytics, and real-time message tracking that ensures critical communications reach citizens when they matter most.
“During incidents, the analytics dashboard enables us to trace message delivery and quantify impact with ease,” says Tay.
Through their partnership with Sinch, OGP has made government messaging even more robust. The platform not only guarantees secure delivery — achieving 95% message delivery within 48 hours and urgent messages within a minute — but also gives government agencies powerful tools for managing their communications. Real-time delivery tracking, message tagging, and detailed analytics help agencies work more efficiently at scale.
For Tay and his team at OGP, this enhanced messaging infrastructure means they can continue focusing on what matters most: building innovative digital services that make life better for Singaporeans.
