How Side Unified Notifications and
Empowered Product Teams to Move Faster
Side Was Scaling Fast But Notifications Were A Drag
Side powers many of the nation’s top-producing real estate agents. As one of the top 10 largest brokerages in the U.S. by sales volume, it helps market-leading agents and boutique companies build and grow their own brands — without the burden of running a traditional brokerage.
Through its white-label platform, Side handles everything behind the scenes — from transaction management and compliance to marketing and CRM — so agents can stay focused on serving clients and scaling their businesses. Trusted by the industry’s best, Side has become essential to agents’ daily work.
As the Side App expanded to support more agent workflows, delivering timely transaction updates became increasingly difficult. Disconnected backend systems made real-time notifications unreliable, exposing gaps in how critical updates were communicated — adding friction for both users and developers.
Introducing new channels like SMS, push, and in-app messaging felt daunting. Without a unified system, important updates were easily missed, product teams moved slowly, and the agent experience took a hit.
A reset, not a rebuild
Side didn’t need to start over. They needed a solution that integrated easily, supported every channel, and let product teams manage notifications themselves.
Courier fit perfectly.
Courier gave product teams full ownership. Templates moved out of code and into a visual editor. Engineers connected event data, and notifications became self-serve.
The rollout was fast and incremental. Side started by centralizing email, which brought immediate consistency. Expanding to SMS, push, and in-app followed naturally. Courier’s team worked closely throughout — guiding setup, answering questions, and helping make the transition smooth.
Product teams now move fast — no engineering required
Courier’s logs and Datadog integration gave teams real-time visibility into delivery and engagement. Issues that once went unnoticed now surface early — no need to pull logs or dig through code.
At the same time, adding new channels became simple. What once felt complex — SMS, push, and in-app notifications — turned into straightforward configuration.
As more teams saw the value, adoption spread. Support gained visibility into delivery. Marketing and growth teams explored new use cases. Courier became Side’s standard messaging layer — scalable, flexible, and owned across the company.
One system. Zero bottlenecks.
Notifications used to be a source of friction at Side — fragmented, inconsistent, and hard to manage. Today, they’re unified, reliable, and invisible.
Product managers launch updates on their own. Engineers stay focused on core product work. Support and growth teams get answers without pulling in development. And agents receive the right messages through the channels they prefer.
Courier didn’t just replace old systems. It gave Side something entirely new — a single, scalable foundation for messaging across the company.
Now, notifications simply work. And that’s exactly the point.
