Resend's Co-founder Highlights Internal 'Dogfooding' Approach for Monthly Reliability Updates

San Francisco Bu Kinoshita, Co-founder and CTO of Resend, an email API platform for developers, recently highlighted the company's deep-seated commitment to reliability, stating that "reliability isn isn t just a metric — it isn s culture." Through a recent tweet, Kinoshita revealed that Resend actively "dogfoods" its own broadcast system to share monthly reliability updates internally with the entire team, underscoring a practical application of their core product. This internal practice ensures transparency and continuous improvement in their infrastructure.

Resend, launched in January 2023 and part of the Y Combinator Winter '23 batch, positions itself as a modern email API designed for developers to build, test, and send transactional emails at scale. The company aims to solve common developer frustrations such as emails landing in spam folders, poor observability, and slow performance. It has quickly gained traction, with over 10,000 developers using the platform to send millions of transactional emails since its inception.

The "dogfooding" strategy, where a company uses its own products internally, is a testament to Resend's confidence in its email infrastructure. By utilizing their broadcast system for critical internal communications like monthly reliability reports, Resend ensures that its team experiences the platform from a user's perspective. This hands-on approach allows them to proactively identify and address potential issues, refining the product's stability and performance.

For an infrastructure company like Resend, which claims 99.9% uptime and focuses on high availability and scalability, this internal testing mechanism is crucial. The monthly updates, as hinted by Kinoshita, likely cover detailed performance metrics and system health, fostering a culture where every team member is invested in the platform's robustness. This dedication to internal scrutiny directly translates into a more reliable service for their external customers.

Resend's emphasis on reliability extends to features like proactive blocklist tracking, faster time to inbox, and managed dedicated IPs, all designed to ensure emails reach their intended recipients. The internal "dogfooding" of reliability broadcasts reinforces their promise of a dependable email sending solution, aiming to set a new standard in the developer-focused email API market.
