Protecting your mailbox with @upstash/ratelimit

In a digital era where email communication is pivotal, a front-end developer at JUST.engineer shared a learning experience about creating a landing page that facilitated customer emails to HR, which inadvertently led to overwhelming spam. Using NextJS for UI and logic, Sendgrid for email handling, and Upstash to manage spam, the developer crafted a solution to handle emails efficiently. The project demonstrated the advantages of NextJS's serverless API routes, and Sendgrid's beginner-friendly email library, while deploying on Vercel for seamless hosting. However, when internet trolls exploited the system, Upstash's rate-limiting capabilities were employed to curb email abuse by limiting requests per period, showcasing an effective real-world problem-solving scenario that highlights the agility of modern web development technologies.
