Overview

This video is a Q&A session with the co-founders of Resend, Bu Kinoshita and Zeno Rocha. They discuss the technologies used to build the Resend platform, the origins of React Email, technical challenges faced during development, and future plans for features like inbound emails and templating. They also touch upon the team size and hiring plans.

Key takeaways

• Tech Stack: Resend utilizes Next.js for its dashboard hosted on Vercel, Express.js for its public API hosted on Railway, and Ingest for background jobs. Tailwind CSS is used for styling, and Radix for building components.
• React Email Origin: React Email was initially a side project born from the pain of building email templates, which eventually evolved alongside Resend.
• Technical Challenges: The most significant technical challenges stem from growth, specifically handling a high volume of requests per second, processing numerous emails concurrently, and building a robust queue system that can reprocess failed messages.
• Future Features: Resend is considering adding inbound email capabilities with webhooks and exploring templating features within the Resend dashboard. An email editor is also in development to empower both technical and non-technical users.
• Team and Hiring: The current team consists of five people. Resend is actively hiring for a Developer Success Engineer role and is open to building relationships with potential hires for future engineering and marketing positions.
