Vialogue is a multi-channel messaging platform powering enterprise communication across SMS, voice, WhatsApp, email, and Google-verified messaging channels. Their platform enables businesses to run promotional, transactional, and automation campaigns at scale—across industries like banking, retail, e-commerce, and healthcare.
With a messaging stack designed for high throughput (12,000 messages per second) and backed by a 99.9% uptime SLA, Vialogue delivers reliable and scalable services. They offer simplified dashboards, multilingual support, direct operator routing, and live campaign insights to enhance customer engagement.
Despite being robust, they needed a more efficient SMS backend—able to integrate with leading operators, handle DLT compliance, and scale for growing campaign volumes. Encapsulated stepped in to build a reliable, high-performance system that addressed these needs.

Despite strong market presence, Vialogue faced critical technical and scalability hurdles that limited their ability to grow and deliver consistent service quality.
The platform needed to process massive SMS volumes at operator scale, requiring throughput in the thousands per second without performance drops.
Ensuring SMS delivery within milliseconds was a challenge, particularly during peak traffic spikes and large campaign sends.
Integrating seamlessly with multiple operators (Airtel, Vodafone, Jio, Videocon) and ensuring DLT compliance added complexity and risk.
Running campaigns with thousands of contacts required robust queuing, smooth UI performance, and fault-tolerant backend processes.
The client needed granular role-based access control (RBAC) to manage permissions securely across teams and organizations.
We engineered a high-performance SMS platform with operator integrations, intelligent routing, and enterprise-grade scalability to meet Vialogue’s growing demands.
Built a queue-based messaging engine capable of processing 12,000+ SMS per second with guaranteed message ordering, fault tolerance, and real-time delivery tracking.
Implemented asynchronous pipelines, Redis-backed queues, and optimized connection pooling to minimize latency and ensure near-instant SMS delivery even during traffic spikes.
Integrated directly with major telecom operators (Airtel, Vodafone, Jio, Videocon) and built seamless DLT compliance workflows for template approval, header mapping, and secure routing.
Developed a scalable campaign module supporting uploads of hundreds of thousands of contacts with background job processing, error handling, and real-time progress tracking.
Designed a user-facing routing dashboard allowing administrators to configure and prioritize SMS routes dynamically, ensuring reliability and cost optimization.
Implemented enterprise-grade RBAC with granular role hierarchies, permission sets, and organization-level controls to ensure secure access management across clients and teams.
