Courier

Courier is a SaaS company focused on helping other software teams send notifications to their users in a more reliable and manageable way. In many products, messaging ends up scattered across codebases and third party tools, which makes it difficult to keep content consistent, route messages to the right channels, and understand whether users are actually receiving them. Courier addresses this by providing a central layer for creating, managing, and delivering notifications across common channels such as email, SMS, push, and in app messaging, with the aim of reducing engineering overhead and giving teams better control over how communication is handled.

The company’s users are typically product and engineering teams building SaaS applications that need to communicate with customers at scale. That includes transactional messages like sign ins, password resets, and billing updates, as well as product notifications and lifecycle messaging. Because notifications sit at the intersection of user experience, deliverability, and compliance, Courier is likely to be used by organisations that care about reliability and auditability, and that want a clearer separation between message content, routing logic, and the underlying delivery providers.

Within the SaaS ecosystem, Courier sits in the developer tooling and communications infrastructure space. It acts as an orchestration layer that can connect to multiple delivery services, rather than being a single channel provider itself. That positioning means the product needs to integrate cleanly with modern application stacks, work well with APIs and event driven architectures, and meet expectations around uptime, monitoring, and security. It also suggests a strong focus on making complex technical workflows accessible to teams that include both engineers and non engineers.

People who tend to thrive at Courier are likely to enjoy building products for developers and working on systems where correctness and reliability matter. Engineering roles may involve API design, integrations, platform reliability, data and event pipelines, and the practical challenges of multi channel delivery. Product, design, and customer facing roles are likely to benefit from an ability to translate between technical constraints and user needs, particularly when the end user is a developer who expects clear documentation, predictable behaviour, and thoughtful defaults.

For job seekers, Courier may appeal if you want to work on infrastructure that directly affects how end users experience a product, while also building tools that make other teams more effective. The work is inherently cross functional, touching product, engineering, and customer outcomes, and it rewards an approach that values clarity, robustness, and good developer experience. If you like solving real operational problems, improving how teams communicate with their users, and working on a platform that sits inside many other products, Courier is the kind of company where that skill set is likely to be valued.
