Notifications are a critical channel for user engagement, growth, and retention, especially in fintech companies where timely alerts can have significant repercussions. Executives from mid-market product orgs emphasized the need for robust notification systems that allow users to control their preferences, with features such as cross-compatible templating across multiple channels like SMS, email, and Slack. However, building such a system requires significant engineering hours and investment, often exceeding $1 million, which is why many companies are now seeking alternatives like Courier, an easy-to-use platform for managing notifications over any channel.
