Resend

Resend is the new email API for developers, designed to build, test, and send transactional emails at scale. Founded in 2023, the company started with an open source project in 2022 when the founders became frustrated by how difficult it was to build modern email templates that worked well across all email clients.

The web has come a long way in the last ten years, but email has been stuck in the past. Resend wants to change that by reimagining what a modern email sending platform should look like. We're a team of engineers who love building tools for other engineers, with the goal of creating the email platform we've always wished we had - one that just works.

Backed by Y Combinator and Andreessen Horowitz, Resend has raised $21M in total funding and powers millions of transactional and marketing emails per day for companies of all sizes. The platform offers SDKs for multiple programming languages including Node.js, Ruby, Python, PHP, Go, Rust, Java, Elixir, and .NET, along with integrations with popular frameworks like Next.js, Remix, Nuxt, Express, and Astro. It also powers React Email, their open source component library that makes creating beautiful email templates without dealing with table layouts and raw HTML.
