How Officevibe Scaled Notifications Across Slack, Microsoft Teams, and Email
When growth exposed the limits of a homegrown notification system
Officevibe’s mission is to help teams build stronger relationships through open communication. The platform enables managers and employees to share feedback, measure engagement, and stay aligned—through channels like Slack, Microsoft Teams, and email.
Notifications power that experience: weekly surveys, meeting reminders, and feedback summaries all depend on reliable delivery. But as Officevibe scaled, their in-house notification system began to crack. Deliverability faltered, duplicate messages appeared, and visibility into errors was limited. Developers spent hours tracing issues without clear insight into what went wrong.
As Technical Product Owner Marc-André Bilodeau Lamontagne put it, the team began “seeing duplicate notifications go out to thousands of users—and we couldn’t even pinpoint why.”
Running two separate notification stacks only made things harder. Without proper idempotency controls, retries sometimes re-sent messages, eroding user trust. And because notifications were hardwired into code, fixing or updating templates slowed down development.
What began as a small technical inconvenience had become a drag on growth. Notifications were essential to the user experience, but managing them was consuming valuable engineering time.
To keep pace with growth, Officevibe needed a system that could deliver reliably across every channel—and scale effortlessly as the business expanded.
Build vs. Buy: Choosing focus over firefighting
At first, Officevibe considered rebuilding their notification system from scratch. But maintaining two separate stacks had already created technical debt, and the team knew how much time a rebuild would consume. They’d need to add idempotency controls, improve visibility, and rework template management—all while continuing to support a fast-growing customer base.
It wasn’t just a question of engineering effort. Notifications were essential to user engagement, but they weren’t core to Officevibe’s mission. Every hour spent fixing infrastructure was time taken from improving the product itself.
When the team compared the cost of rebuilding against integrating Courier, the difference was clear. A rebuild would take twice as long, still require ongoing maintenance, and offer no guarantee of long-term reliability. Courier provided everything they needed out of the box—deliverability, observability, scalability, and a clean developer experience.
As Marc-André Bilodeau Lamontagne explained, Courier even solved problems the team didn’t realize they had: fallback logic across channels, visibility into delivery performance, and built-in scalability. Choosing Courier wasn’t just faster—it allowed engineers to stay focused on what mattered most: building a better experience for teams.
A Reliable Foundation for Multi-Channel Notifications
After moving from their in-house system to Courier, Officevibe immediately saw the difference. Managing and monitoring notifications was off their plate—every survey, invite, and reminder delivered reliably across Slack, Microsoft Teams, and email.
Courier’s native Slack integration proved especially valuable, powering real-time engagement directly where teams collaborate. The team also adopted Courier Automations, which automatically falls back to email if a Slack or Teams message can’t be delivered. It was a feature they hadn’t realized they needed until Courier made it effortless.
As Officevibe’s user base grew, message volume skyrocketed from dozens of surveys a month to over two million. With Courier, that scale required no rebuild, no extra maintenance—just a system that continued to work.
